CITY COUNCIL STAFF REPORT
ITEM NO. 7.3

DATE:

June 22, 2026
TO:

Honorable Mayor and City Council
FROM:

Carl Brown, Public Works Director
SUBJECT:

Hearing to approve the City's 2025 Urban Water Management Plan.

RECOMMENDED ACTION

At the conclusion of the public hearing, it is recommended that the City Council adopt a resolution:

1 .

Adoption of the 2025 UWMP is exempt from the California Environmental Quality Act pursuant to the Water Code.
2 .

Approving the 2025 UWMP.
3 .

Authorizing transmittal to the California Department of Water Resources. 4 .

Authorizing the City Manager to take appropriate and necessary actions to carry out the purpose and intent of this Resolution and to incorporate any necessary amendments as stipulated by the State Department of Water Resources.

SUMMARY
Urban water suppliers are required by the Urban Water Management Planning Act to update and submit Urban Water Management Plans (UWMP) to the California Department of Water Resources (DWR) every five years. Urban water suppliers are also required to hold a public hearing before the UWMP is adopted (Water Code § 10642). The UWMP addresses past, current and projected water demands, water conservation compliance, water resources reliability, recycled water planning, demand management measures, and seismic risk assessment. On March 10, 2026, as required by Water Code § 10621(b), the City has notified all applicable agencies at least 60 days prior to this public hearing. The UWMP was made available for public review prior to consideration for adoption. Notice of the time and place of the public hearing was provided to the public on June 8 and June 15, 2026, in the Valley Times pursuant to Water Code §10642 and Gov’t Code § 6066. Overall, the Livermore Municipal Water (LMW) 2025 UWMP demonstrates that Livermore has a reliable water system and is taking proactive measures to effectively manage that system for the benefit of its customers. The City of Livermore’s 2025 UWMP fulfills state requirements to document long-term water supply planning by evaluating water demand and supply reliability over a 20-year horizon under normal and drought conditions for the Livermore Municipal Water (LMW) service area.

511
The plan projects water demand through 2050 based on land use across residential, commercial, industrial, and park sectors. LMW has met state conservation goals under SB X7-7, achieving 190 gallons per capita per day (GPCD) in 2020 (below the 192 target) and 184 GPCD in 2025, and will continue monitoring and pursuing conservation efforts.

LMW relies entirely on the Zone 7 Water Agency for potable water, sourced from a diversified portfolio including State Water Project imports, groundwater, surface water, and storage programs. Reliability assessments show adequate supply through 2040 under various conditions, though extended droughts beyond 2045 may cause shortfalls, which can be mitigated through conservation.

The City also maintains a strong recycled water program, meeting current demand and projecting a 25% increase, supported by policies requiring its use in new developments. Additional strategies include conservation programs, metering, pricing, public outreach, and system maintenance.

The UWMP also addresses seismic risks, reduced reliance on Delta water, and confirms compliance with environmental regulations.

DISCUSSION
The City of Livermore retained Kennedy/Jenks Consultants, Inc. to prepare this 2025 Urban Water Management Plan (UWMP) for the City of Livermore’s Municipal Water (LMW) system in accordance with the Urban Water Management Planning Act (Act) and its amendments. The Act requires every urban retail water supplier to prepare and adopt an UWMP in years that end in 0 and 5 to document its water supply planning efforts. Urban water suppliers are also required to hold a public hearing before the UWMP is adopted (Water Code § 10642). The UWMP addresses past, current and projected water demands, water conservation compliance, water resources reliability, recycled water planning, demand management measures, and seismic risk assessment. On March 10, 2026, as required by Wat. Code § 10621(b), the City has notified all applicable agencies at least 60 days prior to this public hearing. The UWMP was made available for public inspection prior to consideration for adoption. Notice of the time and place of the public hearing was provided to the public pursuant to Water Code §10642 and Government Code § 6066.

The UWMP supports an urban water supplier’s long-term water resource planning and ensures adequate water supplies are available to meet existing and future water demands. The reliability and efficient use of water supplies are assessed over a 20-year planning horizon during normal, single dry year, and multiple dry year conditions. Overall, the LMW 2025 UWMP demonstrates that Livermore has a reliable water system and is taking proactive measures to effectively manage that system for the benefit of its customers.

It should be noted that this UWMP covers the LMW service area only. The LMW system, which serves a portion of the City of Livermore, is operated and maintained by the City of Livermore Public Works Department’s Water Resources Division (WRD). Water service for the rest of the City of Livermore is provided by the California Water Service Company (Cal Water). Cal Water prepares a separate UWMP documenting its activities.

A summary of the major components of the plan is presented below.

Water Demands (Section 2)
512
This Section describes the current and past water demands in the LMW service area and projects the future water demands to 2050 using a land-use-based methodology. The methodology accounts for projected growth across major water use sectors, including single-family residential, multi-family residential, commercial, industrial and institutional (CII), and park uses.

SB X7-7 Water Conservation Compliance (Section 3)
The adoption of the Water Conservation Act of 2009, also known as the SB X7-7, sets a goal of achieving 20% statewide reductions in urban per capita water use by the year 2020. For LMW, the final 2020 water use target is 192 gallons per capita per day (GPCD). LMW actual 2020 water use was 190 GPCD. This reduction adequately meets the goals of SB X7-7. Therefore, no additional assessment of present and proposed future measures, programs, or policies are required to achieve further water use reductions. LMW’s actual 2025 GPCD was 184 GPCD. Staff will continue to monitor water use and utilize water use reduction methods to maintain this reduction in future water years.

Water Resources, Quality, and Reliability (Sections 4, 6, and 7) LMW purchases 100% of its potable water supply for its service area from wholesaler Zone 7 Water Agency. Zone 7 is a State Water Project (SWP) contractor that wholesales treated water to four retail water agencies, including LMW. Zone 7’s current and planned water supply includes purchased or imported water (SWP, Sites Reservoir), supply from storage (SWP Carryover, Chain of Lakes Conveyance System, Cawelo and Kern County Groundwater Banking Programs), surface water (Arroyo Valle), and groundwater (Main Basin).

Water quality is addressed in the discussions regarding each supply in Section 4. In addition, LMW prepares a consumer confidence report each year that provides the public with the results of water quality monitoring efforts.

Zone 7’s 2025 UWMP includes a Water Service Reliability and Drought Risk Assessment. The assessment compares projected water supplies and demands from 2026 through 2050 under the following hydrologic conditions: normal year, single dry year, and five consecutive dry years. The assessment reflects the expected range of water supply available based on historical use records, hydrologic records, existing supplies and storage options, and expected new facilities and supplies. The assessment concludes that it can meet all retailer demands during normal year, single-dry year, and five- year droughts beginning in 2025, 2030, 2035, and 2040. However, if a drought occurs in five consecutive years starting in 2045 or 2050, during the last year of each drought duration, there will be 14% and 20% shortfall, respectively. The projected shortfall does not consider active water conservation measures. All retailers can fill the gap by conserving water. During the 2014/2015 drought, Livermore Municipal Water customers reduced demand by about 32%, with reductions as high as 42% in many months.

Recycled Water Planning (Section 5)
This section reviews historical recycled water use and projects that future demand will increase by 25% from current levels. All projected demand can be met by the Water Reclamation Plant. The City has a well-developed recycled water program that currently distributes about 1.8 million gallons of recycled water per day on average. Recycled water is provided for several uses including landscape and agricultural irrigation, fire protection, construction, street sweeping and toilet and urinal flushing. The City currently requires all new development within the LMW recycled water service area to use recycled water for outdoor irrigation purposes. The City also encourages developers to use recycled water for toilet flushing inside certain categories of buildings, or to install dual plumbing for possible future use if the tenant is unknown at the time of construction.
513

Demand Management Measures (Section 8)
LMW implements a variety of demand management measures (DMM) to meet its urban water use reduction targets and maintain the reliability of its water supply. Listed below are those DMMs that the UWMP Act and Water Code specifically mention:

Water waste prevention ordinances (Water Conservation Ordinance, Mandatory drought Conservation Measures Ordinance, and Water Shortage Contingency Plan) Metering (Advanced Metering Infrastructure)
Public education and outreach
Programs to assess and manage distribution system real loss Water conservation program coordination and staffing support

Seismic Risk Assessment (Section 9)
As part of LMW’s Water Distribution System Risk and Resilience Assessment (RRA), the City of Livermore evaluated seismic risk to water facilities and identified mitigation measures to lessen the risk.

This plan meets the requirements of the federal Disaster Mitigation Act of 2000 as well as the requirements of Water Code Section 10644.

Reduced Delta Reliance (Appendix B)
The Delta Reform Act of 2009 requires water suppliers to demonstrate consistency with Delta Plan Policy WR P1 – Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance (Cal.

Code Regs. tit. 23, § 5003). WR P1 requires an analysis which needs to be included in a water supplier’s UWMP.

As a water retailer, LMW benefits from Zone 7’s diversified water supplies which include Main Basin groundwater, Arroyo Valle, and the Sites Reservoir Project. In addition, LMW’s own passive water conservation and recycled water use are being used as self-reliant water sources. The analysis demonstrates LMW’s consistency with Delta Plan Policy with reduced reliance on the Delta and improved regional water self-reliance compared to the 2010 baseline.

Environmental Review
California Water Code Section 10652 provides that the California Environmental Quality Act (CEQA) does not apply to the preparation and adoption of Urban Water Management Plans or to projects implementing such plans under Water Code Section 10632.

FISCAL AND ADMINISTRATIVE IMPACTS
There is no fiscal impact to the General Fund from this action. Adequate funding currently exists in the Water Fund to implement the activities discussed in the 2025 UWMP.

IN THE CITY COUNCIL OF THE CITY OF LIVERMORE, CALIFORNIA

A RESOLUTION FINDING THE PROJECT EXEMPT UNDER THE

CALIFORNIA ENVIRONMENTAL QUALITY ACT AND ADOPTINGTHE
2025 URBAN WATER MANAGEMENT PLAN, AUTHORIZING THE

TRANSMITTAL TO THE CALIFORNIA DEPARTMENT OF WATER

RESOURCES

The California Urban Water Management Plan Act codified at Water Code, Div. 6, Pt. 2.6 sections 10610 -10656 requires each urban water supplier providing over 3,000 acre-feet of water annually or serving 3,000 or more connections to update and adopt an Urban Water Management Plan (“UWMP”) at least once every five years.

Urban Water Management Plans are intended to provide a guide to manage urban water demands efficiently and to provide long -term water resource planning to ensure adequate a nd reliable water supplies over a 20 -year planning horizon considering normal, dry, and multiple dry years.

An Urban Water Management Plan is necessary for water agencies to be eligible for State water management grants and loans.

The Delta Reform Act of 2009 requires water suppliers to demonstrate consistency with Delta Plan Policy WR P1 (Cal. Code Regs. tit. 23, § 5003). This can be included as the Addendum to the 2015 UWMP.

In accordance with the California Water Code and other applicable laws, a 60 - day notice was provided to all applicable agencies, and the 2025 draft UWMP has been made available to the public for review and comment prior to a public hearing. A public hearing concerning the 2025 UWMP has been held, and public comments about it have been taken before adoption of the UWMP.

Adoption of the 2025 Plan is exempt from the California Environmental Quality Act (CEQA) because California Water Code section 10652 provides that CEQA does not apply to the preparation and adoption of Urban Water Man agement Plans or to projects implementing such plans under Water Code section 10632.

The Urban Water Management Plan complies with the requirements of the Urban Water Management Planning Act.

NOW, THEREFORE, B E IT RESOLVED by the City Council of th e Cit y of Livermore, that it hereby:

1. Finds that the a doption of the 2025 Plan is exempt f rom the California Environmental Quality Act pursuant to the California Water Code section 10632.

1.1 Overview
This report presents the 2025 Urban Water Management Plan (2025 UWMP) for the Livermore Municipal Water (LMW) system. This section describes the general purpose of the 2025 UWMP, discusses UWMP implementation, and provides general background and information about the City and its service area characteristics. It should be noted that this UWMP covers the City- owned LMW service area only.

It is the stated goal of the City to deliver a reliable and high-quality water supply for customers, even during dry periods. The analysis in this Plan documents that projected water supplies in normal and drought years are adequate to service the City’s customers. Additionally, The City plans to continue water recycling and conservation to meet and exceed water use reduction and reliability goals.

1.2 Purpose
The City of Livermore has prepared this 2025 Urban Water Management Plan (UWMP) for the City of Livermore’s Municipal Water system in accordance with the Urban Water Management Planning Act (Act) and its amendments. The Act requires every urban retail water supplier to prepare and adopt an UWMP in years that end in 0 and 5 to document its water supply planning efforts.

The Act defines an urban retail water supplier as “a water supplier, either publicly or privately owned, that directly provides potable municipal water to more than 3,000 end users or that supplies more than 3,000 acre-feet of potable water annually at retail for municipal purposes”.

The UWMP supports an urban retail water supplier’s long-term water resource planning and ensures adequate water supplies are available to meet existing and future water demands. The reliability and efficient use of water supplies are assessed over a 20-year planning horizon during normal, dry, and multiple dry year conditions.

It should be noted that this UWMP covers the City-owned LMW service area only. The LMW system, which serves a portion of the City of Livermore, is operated and maintained by the City of Livermore Public Works Department’s Water Resources Division (WRD). Water service for the rest of the City of Livermore is provided by the California Water Service Company (Cal Water); Cal Water prepares a separate Urban Water Management Plan documenting its activities.

This UWMP includes information required by the Water Conservation Act of 2009. In February 2008, Governor Arnold Schwarzenegger set a goal of a 20% statewide reduction in per capita daily water use by year 2020. The reduction in per capita daily water use outlined in the 20 x 2020 plan was supported by legislation passed in November 2009 (SBX7-7 Steinberg), also known as the Water Conservation Bill of 2009. The 2025 UWMP reports on compliance with SBX7-7.

Each urban retail water supplier is required to provide a separate Water Shortage Contingency Plan (WSCP) with six shortage stages, a multiple-dry year analysis for five years rather than three years, narratives describing their water demand management measures addressing the nature and extent of each measure implemented over the past five years and include plans to implement demand management measures with targets and progress tracking to achieve water use targets.

UWMPs must quantify and report on distribution system water loss. Urban retail water suppliers must also analyze and define water features that are artificially supplied with water, separately from swimming pools and spas. UWMPs and amendments must be submitted electronically, and standardized tables specified by the California Department of Water Resources (DWR) must be used. Applicable changes have been incorporated into this UWMP. The completed checklist of requirements for LMW’s UWMP is included as Appendix A.

The City of Livermore adopted its first UWMP for the Livermore Municipal Water system in 1992. A WSCP was prepared and adopted in 1991. The City updated and adopted UWMPs for the LMW system, including updates to the WSCP, in 1995, 2005, 2011, 2016, and 2021. This 2025 UWMP updates and supersedes all previous UWMPs.

1.3 Demonstration of Consistency with the Delta Plan for Participants in Covered Actions
Urban water suppliers that anticipate participating in or receiving water from a proposed project (covered action), such as a multi-year water transfer, conveyance facility, or new diversion that involves transferring, exporting, or using water in the Sacramento-San Joaquin Delta (Delta) should provide information in their 2020 and 2025 UWMPs that demonstrates consistency with Delta Plan Policy WR P1, Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance (California Code Reg., tit. 23 § 5003). To demonstrate reduced reliance on the Delta and improved regional self-reliance, urban water suppliers are to:

1. Complete an UWMP.

2. Identify, evaluate, and commence implementation of programs and projects included in the UWMP that are locally cost effective and technically feasible in reducing reliance on the Delta.

3. Include expected outcome for measurable reduction in Delta reliance and improvement in regional self-reliance in their UWMPs, commencing in their 2015 UWMPs, and continuing their subsequent UWMPs. Programs and projects identified above will reduce the amount or percentage of water used from the Delta watershed. For the purposes of reporting, water efficiency is considered a new source of water supply.

LMW, as a retailer of Zone 7 Water Agency, anticipates participating in a covered action and is therefore required to demonstrate reduced Delta reliance. Appendix B of this UWMP demonstrates LMW’s consistency with Delta Plan Policy WR P1.

1.4 Basis for Preparing a Plan
In accordance with the California Water Code (CWC), urban water suppliers with 3,000 or more service connections, or supplying 3,000 or more acre-feet of water per year (AFY), are required to prepare a UWMP every five years. In 2025, the City of Livermore provided water for municipal purposes to 10,923 active connections, thereby meeting the requirement for preparing an UWMP. The City of Livermore manages only the Livermore Municipal Water system, which is Public Water System Number 01-10-001.

1.4.1 Relationship to Other Planning done by LMW
LMW has plans and policies to expand and provide an adequate water supply and water quality for the City of Livermore. The plans and policies include:
 Water Master Plan (WMP) – The WMP provided an evaluation of LMW’s water system’s ability to meet existing and project buildout water demands and identified improvements needed to address system deficiencies.
 Recycled Water Master Plan (RWMP) - The RWMP provided a plan for the City to implement recycled water in a phased manner as technical, funding, partnering, and other factors align to make recycled water expansion feasible.  Local Hazard Mitigation Plan (LHMP) – The LHMP was developed to identify potential hazards to LMW and formulate mitigation measures for future protection of the LMW’s critical infrastructure and the community’s safety with respect to the LMW’s facilities and services.
 In general, regional water resources planning is also coordinated with LMW’s wholesaler, Zone 7 Water Agency (Zone 7).

1.4.2 Relationship to Water Shortage Contingency Plan
LMW has prepared a separate WSCP which contains and expands upon the information that was in the 2020 UWMP. The WSCP is included as Appendix D to this 2025 UWMP update.

1.5 Structure and Organization of the Plan
The plan is organized as follows:
 Section 1: Introduction / Lay Person’s Description
 Section 2: Water Demands
 Section 3: SB X7-7 Baseline and Targets
 Section 4: Water Resources

1.6 Implementation of the Plan
LMW updates the UWMP every five years, documenting the latest results of water supply planning efforts including other planning processes that integrate with the UWMP. This includes the City of Livermore General Plan, Water Master Plan, Recycled Water Master Plan, and regional water reports such as wholesale water agency Zone 7’s UWMP and associated regional demand projections, Groundwater Management Plan for the Livermore-Amador Valley Groundwater Basin, and Water Supply Evaluation Update. Coordination and outreach are key elements to developing the UWMP, and each of these planning efforts relies on information found in the other documents to support and enhance the plan.

1.6.1 Joint Preparation of the Plan
The UWMP Act requires water suppliers to coordinate the preparation of its plan with other appropriate agencies in the area. This includes other water suppliers that share a common

Table 1-4 summarizes the efforts LMW has taken to include the various City departments, agencies, and citizens in the preparation of this document.

LMW purchases all of its potable supplies from Zone 7, the wholesale water supplier. Zone 7 has provided LMW staff with water use projections in five-year increments from 2025 to 2050.

Zone 7 staff has also provided City of Livermore staff with information on existing and planned sources of water over the same 5-year increments from 2025 through 2050 and for average, single, and multiple-dry years for inclusion in this 2025 UWMP.

During the preparation of this UWMP, staff worked particularly closely with Zone 7 staff and the other retailers to ensure consistency. Tri-Valley water retailers including Cal Water, Dublin San Ramon Services District, City of Pleasanton and City of Livermore (Retailers) met several times during the development of Zone 7’s UWMP to discuss and provide necessary information including service area populations, water demand projections, and recycled water plans. Zone 7 staff completed their UWMP early to assist Retailers in preparing their individual UWMPs, and to ensure consistency of supply and demand projections between the Retailer and Zone 7 plans. Livermore staff coordinates closely with Zone 7 to project accurate demands, ensuring that Zone 7 can plan for and provide appropriate water deliveries. Due to the wholesale/retail relationship between Zone 7 and City of Livermore, staff relied on Zone 7 for information necessary to develop this 2025 UWMP.

1.7 System Description

1.7.1 Service Area Physical Description
As noted earlier, the LMW service area comprises portions of the City of Livermore, with the remainder of the City served by Cal Water. Founded in 1869, the City of Livermore is the easternmost city in the San Francisco Bay Area, the gateway to the Central Valley. Protection by the coastal range provides the Livermore Valley with a mild climate that enhances the pursuit of a more relaxed, less congested lifestyle. The City of Livermore is California’s oldest wine region, framed by award-winning wineries, farmlands and ranches. Located in Alameda County, the City is a public entity that operates as a Council-Manager government.

1.8 Population, Demographics, and Socioeconomics
The City of Livermore is located in a mid- to high-income area relative to many parts of California and has no significant employment, economic or industrial factors that will significantly impact the water supply relative to other local communities. According to the U.S. Census Bureau’s American Community Survey (ACS), the 2024 median household income in Livermore was $169,251 compared to the $100,149 statewide median household income and the $129,130 countywide median household income. In addition to a high median income, only about 4.4% of the Livermore population was living below the poverty line as of 2023, compared to a statewide poverty rate of about 17.7% in 2023. Relative to the rest of the state, water customers in the City of Livermore historically have had the financial resources available to support the water rates needed to develop and maintain a safe and reliable water supply.

Due to the level of additional public and private landscape present in well-developed suburban communities such as the City of Livermore, per capita water consumption in the City is likely higher than in other communities with less irrigated landscaping. 73% of Livermore households are classified as “family households”, with approximately 38% of households having children under the age of 18. By comparison, only about 69% of California households are classified as “family households”, with about 35% having children under the age of 18. Additionally, approximately 74% of housing units in Livermore are owner-occupied, compared to 56% statewide.

To coordinate regional planning efforts, Zone 7, the City’s water wholesaler, conducted a 2025 Tri-Valley Municipal (Tri-Valley) and Industrial Water Demand Study to develop a regional, land- use based water demand forecasting model that produces key inputs that can be used by both Zone 7 and the Tri-Valley retailers. As part of this study, population projections were developed from 2025 through 2050 via linear interpolation of the estimated 2025 water service area population and the anticipated 2045 buildout population. The model assumes that buildout occurs in 2045 and that the City’s population remains constant once buildout is reached. The 2045 buildout population was developed using the expected growth of the City based on the City’s land use plans plus additional specific anticipated growth due to the development of the Isabel Neighborhood and Midtown Specific Plan Area. The Isabel Neighborhood is a 1,100-acre area within the City’s service area that is projected to include residential areas, commercial use, and open space. The Midtown Specific Plan Area is approximately 400 acres and currently includes a mix of existing commercial, office, industrial, and residential land uses. The predominant existing land use is low intensity, light industrial.

Between general growth within the City’s service area boundaries (infill projects) and the specific development plans for the Isabel Neighborhood and Midtown Specific Plan Area, the City anticipates over 100% service population increase in LMW service area.

The current and projected populations within LMW’s service area are presented in Table 1-7.

1.10 Climate
The City of Livermore has a Mediterranean climate, with warm, dry summers and cool, moist winters. The average daily temperature in Livermore is 59oF with average annual high at 74.0oF and average annual low temperature at 46.4oF1. The average rainfall and evapotranspiration in Livermore are approximately 18.8 inches and 54.1 inches respectively1, making the Livermore area relatively dry and arid, which may increase the associated irrigation demands within the LMW service area when compared to cooler, wetter locations.

Average monthly temperature, precipitation, and evapotranspiration (ETo) data for the City of Livermore is below in Table 1-8 and Figure 1-3.

1.11 Potential Effects of Climate Change
Water demand and use patterns may be impacted by climate change. Climate change models have predicted that potential effects from climatic changes will result in increased temperature, early snow melt, and a rise in sea level.

In the 2023 update of the DWR California Water Plan, the implications of future climate conditions are evaluated. These changing hydrological conditions could affect future planning efforts, which are typically based on historic conditions. The California Water Plan identifies the following probable impacts due to changes in temperature and precipitation:
 More winter runoff and less spring/summer runoff due to warmer temperatures.  Greater extremes in flooding and droughts.
 Greater water demand for irrigation and landscape water due to increased temperatures and their impacts on plant water needs.
 Increased sea level rise, increased threat of coastal flooding, and saltwater intrusion into coastal groundwater aquifers.

These hazards that were assessed to have potential impact from climate change include flood and wildfire.

Increased irrigation demand, increased evaporative losses due to warmer temperatures, and a longer growing season are also anticipated when temperatures rise. Increasing the use of recycled water for these demands could mitigate the effects of climate change on water demand.

1.12 Reduced Delta Reliance
Appendix B of this UWMP demonstrates LMW’s consistency with Delta Plan Policy WR P1.

Overall, Livermore shows a reduction in reliance on the Delta Watershed with an increasing percent of supplies contributing to regional self-reliance projecting out to 2050.

2.1 Overview
This Section describes the current and past water demands in the LMV service area and projects the estimated future water demands to 2050 based on the assumed reduction in per capita water usage required by the Water Conservation Bill of 2009. Accurately tracking and reporting current water demands allows City staff to properly analyze the use of its resources and conduct water supply planning.

2.2 Non-Potable Versus Potable Water Use
LMW provides both potable water and recycled water to customers within its municipal water service area. The City also supplies some recycled water to the City of Pleasanton for landscape irrigation uses outside the Livermore service area.

Potable water is water that is safe enough to drink and prepare food, and which typically has had various levels of treatment and disinfection. LMW purchases all its potable water supply from wholesaler Zone 7 and has no additional potable supply sources during normal operations.

LMW does maintain emergency interties with other water retailers in the area to provide back-up supplies for short-term service interruptions.

Recycled water is municipal wastewater that has been treated to a specified quality to enable it to be used again for a beneficial purpose or discharged from a wastewater facility. The City of Livermore owns and operates a wastewater treatment facility and produces recycled water for beneficial purposes to offset potable water use. Recycled water is addressed comprehensively in Section 5.

Raw water is untreated water that is used in its natural state or with minimal treatment. LMW has an untreated water allocation from Zone 7 that was formerly used for irrigation in Springtown Golf Course. After the golf course closed the business, the City has not delivered any raw water to other its customers and has no foreseeable users to use raw water. Thus, the full raw water allocation was not retained in projected demand calculations.

2.3 Past, Current, and Projected Water Use by Sector
Sections 10631(e) (1) and (2) require urban water suppliers to quantify, to the extent that records are available, past and current water use, and projected water use over five-year increments.

2.3.1 Water Use Sectors Listed in Water Code
Water suppliers are required to identify the uses among sectors of water customer classes, including, but not necessarily limited to, all of the following uses: (1) Single-family residential; (2) Multifamily; (3) Commercial; (4) Industrial; (5) Institutional and governmental; (6) Landscape; (7) Sales to other agencies; (8) Conjunctive use; (9) Groundwater recharge; (10) Saline water

These classifications were used to analyze reported consumption for water use patterns by sector. The LMW customer classifications are represented in sectors 1, 2, 3, 5, and 6. LMW has no reportable uses in the remaining sectors.

2.3.2 Water Use Sectors in Addition to Those Listed in Water Code There are no additional water use sectors represented in the City’s demands.

2.3.3 Past Water Use
Actual demands from 2020 and 2015 for LMW are summarized in Tables 2-1A and 2-1B.

2.3.4 Distribution System Water Losses
System water losses were determined using LMW’s annual water loss audits. Losses were assumed to be the difference between water supplied to LMW by Zone 7 and total authorized usage. In 2025, Zone 7 supplied LMW with 1,901 MG of water, and LMW reported 1,704 MG of authorized usage (1,701 MG of billed metered usage and 3 MG of unbilled unmetered usage),

2.3.5 Current Water Use
Current (2025) potable water demands presented in Table 2-3 (DWR Table 4-1R) are based on metered, delivered water consumption information from 2025, and are measured in million gallons. There is no reportable actual raw water demand in 2025, however, the City of Livermore is entitled to 185 AFY (60 MGY) of raw water provided by Zone 7 Water Agency. This raw water allocation was formerly used for irrigation at the Springtown Golf Course. There are no reportable actual or projected water use for sales to other agencies, conjunctive use, groundwater recharge, saline water intrusion barriers, or agricultural uses.

In 2025, LMW provided water service to 10,923 service connections (and an additional 21 connections for domestic city and fire uses). Table 2-3 summarizes the LMW’s 2025 water usage by category, which totaled approximately 2,481 million gallons of water.

Between 2020 and 2025, the City’s municipal water system grew by about 401 service connections, or about 4%, to 10,923 service connections. Total volume of water sold decreased by approximately 12% between 2020 and 2025. This is likely to reflect a rebound in water consumption within the past five years following the conservation measures enacted in the 2020/2023 drought.

Total commercial use increased by approximately 3 MG, or about 1% from 2020 to 2025, while landscape usage decreased by approximately 12%, and institutional usage decreased by 15% during this period. Single family usage decreased by approximately 15% and multi-family residential usage increased by approximately 1% between 2020 and 2025.

2.3.6 Projected Water Use
Projected water use, also called demand projection, for the City of Livermore is summarized in Table 2-4 (DWR Table 4-2R). LMW developed the demand projection with Zone 7 Water Agency through the Tri-Valley Municipal and Industrial Water Demand Study (Regional Demand Study) in 2020 and 2025. Demand projections were developed using a land-use-based methodology. The methodology is briefly explained as follows:
 Residential Indoor demands are calculated by first projecting population based on parcel area multiplied by the expected dwelling unit density (number of dwelling units per acre) and the average number of people per dwelling unit. Population is then multiplied by indoor residential per capita use (gallons per person per day of indoor use).  Residential Outdoor demands are calculated by multiplying area of residential land by an outdoor water demand factor (MG/acre). The outdoor water demand factor was calculated using historic water consumption reported by each agency. Historic residential water consumption was disaggregated into estimates of indoor and outdoor water use per property.

The CII water demand factor was calculated using historic water consumption reported by each agency. CII parcels were sorted in various land use categories according to county assessor data.  Water losses are calculated by multiplying number of service connections by “real losses per connection per day” and "apparent losses per connection per day" which are both volumetric units calculated by agencies as part of annual water loss reporting requirements.
 Unmetered Consumption is authorized consumption from unmetered uses like firefighting or construction meters that is calculated by multiplying total potable demands by an estimated percent unmetered.

The focus of the Regional Demand Study was developing an estimate of buildout demand, which is expected to occur in 2045. Demands for 2050 were assumed to be the same as in 2045 for industrial, institutional/governmental, and landscape. In addition to using historical data and development planning documents, the Regional Demand Study considers other factors such as passive water conservation, climate change, and price elasticity.

The values contained in this table/figure are planning level estimates and there is an uncertainty associated with each of these values.

LMW’s raw water allocation from Zone 7 is not included in this table as there is no foreseeable demand.

Projections in this table were based off of the total volumes projected in the Zone 7 Regional Demand Study. These were broken down into the appropriate DWR usage categories based on the projected split between usage categories reported in the EKI 2025 Demand Study for Zone 7. The 2025 Demand Study reported residential usage as residential indoor and outdoor usage – this was converted to a split between single family residential and multi- family residential usage based on an analysis conducted by LMW that interpolated SFR and MFR usage from actual 2025 usage to projected buildout usage.

Potable water demand projections for water years 2045 and 2050 are estimated to remain level as the City of Livermore Municipal Water service area reaches buildout due to the Urban Growth Boundary (UGB). The 2050 demand projection is slightly lower than the 2045 value due

Livermore has an UGB that corresponds with Alameda County’s Urban Growth Boundary. Livermore voters approved the South Livermore Urban Growth Boundary Initiative in 2000; and a North Livermore Boundary Initiative in 2002.

In addition to delivering potable water, the City also meets some of the water demand in the City of Livermore by using recycled water. Table 4-4 (DWR Table 6-9R) reflects the estimated projected amounts of recycled water that will be delivered in each water year based on estimates provided by LMW.

LMW provides the five-year demand projections for its municipal water service area to Zone 7 and requests confirmation of the wholesale water agency’s ability to meet the water demands.

Zone 7 provided the response to the request for verification. Based on the response, Zone 7 can meet the requested demands through implementation of water supply projects identified in the Zone 7 Water Supply Evaluation Plan (discussed in further detail in Section 7).

2.3.6.1 Current and Projected Land Use
As discussed in Section 1.9, current land use in the City of Livermore is primarily residential, industrial, and open space. Much of the City’s major land use changes are expected to come from the Isabel Specific Plan Area and Midtown Specific Plan Area. The two Specific Plan Areas are the primary drivers of housing growth, accounting for over 10,000 units within the LMW service area.

As shown in Figure 2-1, the Isabel Neighborhood Specific Plan (INSP) designation applies to the northwest area of the City. The INSP seeks to create a safe, vibrant, complete neighborhood that includes amenities for residents, workers, and students and supports transit ridership and citywide goals for increased transportation options, housing choices, and economic vitality. This designation is implemented through the INSP which establishes specific land use designations and development standards to guide development of the area surrounding the future Valley Link station in the I-580 median at Isabel Avenue.

General Plan 2045 envisions a future Midtown Specific Plan to accommodate housing and job growth on the eastern side of the city. The area is part of a regional priority development area and is roughly bounded by Southfront Road to the north, South Vasco Road to the east, the Union Pacific Railroad tracks to the south, and Las Positas Road to the west (approximately 400 acres). The Midtown area currently includes an assortment of commercial, office, industrial, and residential land uses. Given the proximity of the existing Vasco Ace Station and the possibility of a future Valley Link station contemplated in the area, General Plan 2045 envisions a comprehensive mix of multifamily residential and job supporting land uses in varying proportions to create a transit-supportive, complete neighborhood, with housing, jobs, and services. The location and intensity of future land uses would be determined through a Specific Plan process.

In addition to the two primary Specific Plan Areas, the City also has a list of “Reasonably Foreseeable Development Projects” including the developments located in El Charro area and South Livermore area. These developments were included in the 2025 Zone 7 Demand Study and are shown on Figure 2-2.

However, the Isabel Neighborhood will be served, in part, by recycled water for residential irrigation. The new housing units in the Midtown area will primarily be multi-family units. The water demand for irrigation use will be significantly lower than that for single-family units. Therefore, the overall potable water demand will not increase as sharply as population increases.

2.3.6.2 Coordination with Land Use Agencies to Develop Water Projections Water demand and population projections for the City of Livermore are developed in conjunction with Zone 7. The 2025 Zone 7 Demand Study developed population and demand projections for all the Tri-Valley water retailers (LMW, Cal Water, the City of Pleasanton, and Dublin San Ramon Services District (DSRSD)). The water projections in the 2025 Zone 7 Demand Study were supported by the 2020 Demand Study and LMW’s 2017 Water Master Plan. As noted earlier, the 2025 Demand Study assumes that the City of Livermore reaches buildout (i.e., completion of all planned development projections including the Isabel Neighborhood) in 2045 and reports projected population and water demands in five-year increments between 2025 and 2045 buildout via linear interpolation with consideration of growth timing. The 2025 Zone 7 Demand Study projects that the City of Livermore will see approximately 2,636 MG of annual water usage at buildout.

In addition to their collaboration on the 2025 Zone 7 Demand Study, the Tri-Valley water retailers met during the development of their UWMPs to discuss and provide necessary information to ensure that Zone 7 can plan for and provide appropriate water deliveries to their retailers. Zone 7 staff also coordinate with staff from the LMW and the other Tri-Valley retailers at the operational and policy level to improve system operations or plan for future supplies.

2.3.6.3 Effects of Codes, Standards, and Ordinances
The water demand projections developed in the 2025 Zone 7 Demand Study incorporated passive water conservation, which refers to water savings from regulatory drivers such as codes, standards, and ordinances that result in a decrease of water use, typically due to the replacement of inefficient water fixtures with more efficient models. The demand projections included corrections for the following items:
 Replacement of residential fixtures, including toilets, showerheads, washers, and dishwashers.
 Replacement of commercial/industrial fixtures, including toilets and urinals.

The corrections used in the 2025 Zone 7 Demand Study projections are reflective of the codes and standards set for flow rates of plumbing fixtures in new construction, including the CALGreen Building Code, the California Plumbing Code, California Water Code, and California Appliance Efficient Standards

2.3.6.4 Effects of Climate Change on Water Use
The 2025 Zone 7 Demand Study accounts for changes in water use due to climate change by incorporating a 5% increase in outdoor water demands linearly starting from 0% in 2025 and reaching 5% in 2045.

2.3.7 Characteristic 5-Year Water Use
The estimated expected gross potable water use for the next 5 years without drought conditions is shown in Table 2-5. The estimates in Table 2-5 were provided by Zone 7 and based on actual 2025 deliveries, retailer requests through 2025, and the projections interpolated from the date provided. The estimates in Table 2-5 are the same as the estimates shown in Table 7-6.

2.3.8 Low Income Projected Water Demands
California Water Code 10631.1 requires water retailers to include projected water use for lower income single-family and multi-family households in projected water demands. A lower income household has an income 80% below the Bay Area median income, adjusted for family size.

According to the City of Livermore 2023 to 2031 Housing Element (Housing Element) adopted March 13, 2023, 28.7% of City of Livermore households have an income below 80% of the Area Median Income.

Livermore is served by the City’s Livermore Municipal Water and Cal Water. It would be difficult to determine the exact number of lower income households in each service area. Therefore, projections assume 28.7% of the City’s Livermore Municipal Water demands are attributed to low-income households. For future development, LMW assumes 15% of the housing units are for lower-income families. The projections shown previously in Table 2-4 (DWR Table 4-2R) include water use for single family and multi-family residential housing needed for low-income households, as identified in the Housing Element. Table 2-6 presents the projected lower income potable water use. Table 2-7 (DWR Table 4-3R) presents portion of projected water demands for lower income single family and multi-family households. The projected water use is based on the method provided in the UWMP Guidebook.

3.1 Existing and Target Per Capita Water Use
The adoption of the Water Conservation Act of 2009, also known as the SB X7-7, addresses urban and agricultural water conservation. The Water Conservation Act sets a goal of achieving 20% statewide reductions in urban per capita water use by the year 2020. Each urban water supplier, such as the LMW system, must determine baseline water use during their baseline period and target water use to be met for the years 2015 and 2020, reducing daily per capita water use as defined in SB X7-7.

In its 2010 UWMP, the City first calculated its 2015 and 2020 Urban Water Use Targets by applying Methodology 3 to calculate baseline daily per capita water use, as well as Part II, Section D of the Guidebook to develop a baseline period and water use targets required by SB X7-7. The Water Conservation Bill of 2009 includes a provision that an urban water supplier may update its 2020 urban water use target in its 2015 UWMP and may use a different target method than was used in 2010.

After examining a sample of data from Department of Finance (DOF), DWR determined that significant discrepancies exist between DOF’s projected populations for 2010 (based on 2000 U.S. Census data) and actual population for 2010, based on 2010 U.S. Census data. Therefore, if a water supplier did not use 2010 Census data for their baseline population calculations in the 2010 UWMP (the full census data set was not available until 2012) DWR determined that these agencies must recalculate their baseline population for their 2020 UWMPs using 2000 and 2010 Census data. Therefore, baseline and target gallons per capita per day (GPCD) values in the 2010 UWMP were modified accordingly in the 2020 UWMP, and standardized tables in the SB X7-7 Verification Form were submitted with the 2020 UWMP. The 2020 UWMP reported no changes to the baseline and targets set in the 2010 UWMP.

3.1.1 Base Daily Per Capita Water Use for SBX7-7 Reduction SB X7-7 requires urban water retailers to determine their baseline daily per capita water use measured in GPCD over a 10-year or 15-year baseline period. Urban water retailers that used less than 10% of recycled water in the year 2008 must use a 10-year baseline period. The 10- year baseline period is defined as a continuous 10-year period ending between December 31, 2004 and December 31, 2010.

Staff re-evaluated potable and recycled water supply data for the year 2008. During 2008, LMW supplied 305 MG of recycled water, compared to 2,636 MG of total water deliveries. Therefore, approximately 11.6% of the 2008 water demand in the LMW water service area was met with recycled water. Under the Water Conservation Bill of 2009, water suppliers who met at least 10% of the 2008 demand using recycled water may elect to extend the multi-year base period from 10 up to 15 years.

LMW selected the following baseline periods:
 10-year Baseline Period: 1999 to 2008
 5-year Baseline Period: 2004 to 2008
It should be noted that the 10-year and 5-year Baseline Periods are the same as reported in City’s 2020 UWMP.

3.1.2 Base Daily Per Capita Water Use
Daily Per Capita Water Use is reported in gallons and is referred to as “Gallons per Capita per Day” or “GPCD”. The GPCD was calculated for each of the baseline years and for the compliance year 2020. Annual gross water use was divided by annual service area population to calculate the annual GPCD for each year in the baseline periods. GPCD calculations reflect revised service area population estimates from the DWR Population Tool based on U.S. Census data and electronic maps as discussed in Section 1.8.

Using the revised service area population estimates and measured gross water use, the Base Per Capita Water Use for each year from 1989 through 2010 were calculated. This annual per capita water use data was used to calculate 10- and 15-year averages for the various potential 10- and 15-year base periods ending in 2004 through 2010. As previously discussed, LMW met more than 10% of its 2008 water demands with recycled water and is entitled to use up to a 15-year baseline period for determining Base Per Capita Water Use. However, based on an analysis of the data, the City elected to use a 10-year baseline period.

The LMW baseline daily per capita use were calculated in the 2020 UWMP as follows:
 10-year Baseline Daily per Capita Water Use:
 240 GPCD for period 1999 to 2008.
 This value is 45 GPCD greater than the value calculated in 2010 UWMP (194.6 GPCD).
 5-year Average Baseline Daily per Capita Water Use:
 236 GPCD for period 2004 to 2008.
 This value is 41 GPCD greater than the value calculated in 2010 UWMP (195.4 GPCD).

Based on the guidance for calculating Minimum Water Use Reduction Requirements, the 2015 Water Use Target was set at the mid-point between the 10-year baseline per capita water use and the 2020 water use target. Using a Base Per Capita Water Use of 240 GPCD and a 2020

The per capita water use in 2015 was 141 GPCD which was well below the target amount.

3.1.3 Compliance Water Use Targets
LMW’s 2020 GPCD was 190 GPCD. The 2020 GPCD was below the final 2020 target of 192 GPCD, and therefore no additional assessment of present and proposed future measures, programs, or policies have been considered to achieve further water use reductions. LMW is not a wholesale supplier.

3.1.4 Achievement of Target
As shown in Table 3-1, LMW has met their 2020 water use target and achieved a water use reduction of approximately 20.8% when compared to the 10-year water use baseline of 240 GPCD. This reduction adequately meets the goals of SB X7-7. LMW’s actual 2025 GPCD was 184 GPCD. Therefore, LMW also met their 2020 water use target in 2025. LMW will continue to monitor water use and utilize water use reduction methods to maintain this baseline reduction in future water years.

4.1 Overview
This chapter describes and quantifies existing and future sources of water available to the City of Livermore’s LMW system, and discusses the origin of the water supply, water quality, quantity issues, and actions or projects anticipated to meet future water demands. Water volumes presented in this chapter reflect expectations for average or normal hydrologic year conditions.

4.2 Imported Supplies
The City’s LMW system purchases all of its potable water supply for its service area from wholesaler Zone 7 Water Agency. Zone 7 is a multi-purpose agency that oversees water-related issues in the Livermore-Amador Valley. Zone 7 is a State Water Project (SWP) contractor that wholesales treated water to four retail water agencies, including the City of Livermore, and uses a combination of water supplies and water storage facilities to meet its customers’ water demands. These include imported surface water from the SWP, water transferred from the Byron Bethany Irrigation District, local surface runoff captured in Del Valle Reservoir, groundwater extraction from the Livermore Valley Main Groundwater Basin, non-local groundwater storage in the Semitropic Water Storage District and Cawelo Water District, and future local storage in the Chain-of-Lakes. Zone 7 completed an update to its 2011 Water Supply Evaluation (WSE Update) in early 2016 to reassess its long-term water supply. The WSE Update provides a basis for Zone 7’s water supply projections as included in Zone 7’s 2025 UWMP. Table 4-1 (Zone 7 2025 UWMP DWR Table 6-8W) and Table 4-2 (Zone 7 2025 UWMP Table 6-9W) below from Zone 7’s 2025 UWMP indicate 2025 Actual water sources supplies and projected Normal Year water sources supplies.

Furthermore, the City of Livermore produces and distributes recycled water, which offsets a significant amount of potable water demand that would otherwise need to be met with imported water. The City currently supplies over 20% of the municipal water service area demands with recycled water.

In addition to efforts to minimize demand, the City supports Zone 7’s efforts to maximize the use of local runoff via surface storage in Lake Del Valle, and future storage in the Chain of Lakes to minimize reliance on imported water. The City also supports Zone 7’s groundwater basin management and recharge efforts, which help to reduce the amount of imported water needed.

4.2.1 Zone 7 Water Supply Options

4.2.1.1 State Water Project
Purchased water from the SWP is Zone 7’s largest water source, providing over 90% of the treated water supplied to its customers on an annual average basis2. SWP water moves through the Sacramento-San Joaquin Delta (Delta) before it is conveyed by the California Aqueduct and the South Bay Aqueduct (SBA) to Zone 7's water facilities. The instability of the aging levees in the Delta (including their vulnerability to seismic events and climate change), regulatory uncertainty, water quality issues including saltwater intrusion, and the declining health of the Delta ecosystem all challenge the long-term reliability of the SWP. Zone 7 and other SWP contractors are currently working with DWR and other key stakeholders to address the many complex issues undermining the Delta through the proposed Delta Conveyance Project.

The Delta, a key conveyance component of the SWP, is increasingly threatened by ecosystem considerations, seismic risk, and climate change/sea level rise, reducing the reliability of the SWP system. The Delta Conveyance Project (DCP) reduces these risks and partially restores the SWP’s projected reliability. In early 2019, consistent with Executive Order N-10-19, the state announced a single tunnel project, which proposed a set of new diversion intakes along the Sacramento River in the north Delta for SWP. In 2019 the California Department of Water Resources (DWR) initiated planning and environmental review for the single tunnel Delta Conveyance Project (DCP) to protect the reliability of SWP supplies from the effects of climate change and seismic events, among other risks. On December 21, 2023, DWR certified the Environmental Impact Report and approved the DCP selecting “Bethany Reservoir Alignment” for further engineering, design, and permitting. DWR received the Incidental Take Permit for the DCP from the California Department of Fish and Wildlife in February 2025. DWR is in the process of obtaining a change in point of diversion permit from the State Water Resources Control Board to add the two proposed DCP diversion intakes to the SWP water rights. In October 2025, DWR certified that DCP is consistent with the Delta Plan. DWR is continuing with design refinements, environmental planning and permitting through 2026-27, including resolving appeals on its Delta Plan certification. DCP will potentially be operational in 2045 following extensive planning, permitting and construction.

4.2.1.1.1 Source Water Quality
Until the DCP is constructed and operational, there continue to be water quality concerns associated with transport through the Delta. In 1982, DWR formed the Interagency Delta Health Aspects Monitoring Program to monitor water quality in the Delta and protect human health. The program was renamed the Municipal Water Quality Investigations Program (MWQI Program) in 1990. From a municipal water supply perspective, water quality issues in the Delta are associated with salinity from seawater intrusion, wastewater effluent discharges, agricultural drainages from the islands, and recreational activities. Water quality issues of specific concern to Zone 7 are:
 Algal byproducts: Parameters of concern include compounds that cause taste-and-odor (T&O) and algal toxins. T&O is primarily a problem in the warmer months, when algal blooms may be present. It can affect supplies from the Delta and from Lake Del Valle (which stores SWP water). Algae produce geosmin and 2-methylisoborneol (MIB), which are key T&O-causing compounds in surface water supply. Algal toxins derived from blue-green algae can also be a concern. Zone 7’s ozonation facilities (installed at the Del Valle Water Treatment Plant (DVWTP) and Patterson Pass Water Treatment Plant (PPWTP)) effectively treat algal byproducts. Without ozonation, high levels of algal byproducts in both Delta and Lake Del Valle supplies may necessitate temporarily switching to groundwater supplies; blending of sources is also an option depending on the source of algal byproducts and severity.
 Total and dissolved organic carbon (TOC/DOC): Zone 7 treats organic carbon with coagulant and disinfectant chemicals, and therefore higher levels of organic carbon increase costs. In addition, TOC/DOC help form disinfectant byproducts (DBPs), which are regulated compounds in drinking water. Historically, Zone 7’s water treatment plants (WTPs) have managed high TOC/DOC by increasing coagulant dosages. However, this operational change results in greater sludge production and limits plant production. The use of ozone reduces coagulant and chlorine demands, thus reducing typical chlorination DBPs; however, formation of ozonation DBPs, such as bromate, will need to be controlled.
 Turbidity: Like TOC/DOC, turbidity affects the amount of chemicals used in treatment and Zone 7’s ability to meet drinking water standards. It can also reduce the production capacities of Zone 7’s WTPs, requiring increased groundwater production under high demands. Coagulant dosages can be adjusted to address high turbidity (which can happen after big storms), but if filters require more frequent backwashing, then production may be decreased.
 Salinity or TDS: Salinity has significant impacts on SWP operations and the availability of water. To meet the salinity objectives in the Delta, water exports from the Delta may be restricted, reducing the amount of water supply available during certain times of the year. Salinity intrusion can be a problem during dry years, when there is insufficient freshwater to repel salinity. Sea level rise due to climate change is also expected to increase salinity in the Delta. Finally, levee breaks—due to earthquakes and other factors—would result in significant saltwater intrusion from the Bay as water floods affected islands in the Delta that are below sea level.

Filter clogging reduces plant production capacities and could require supplemental groundwater use.

As noted above, Zone 7 has state-of-the-art ozonation facilities at the DVWTP and PPWTP. Ozonation improves treatment of T&O, TOC/DOC, turbidity, and algal blooms and significantly increases the surface water system’s reliability.

In 2008, the SBA contractors (Valley Water, and Alameda County Water District [ACWD], and Zone 7) developed the SBA Watershed Protection Program to protect water quality once the water from the Delta reaches the SBA. The primary objectives of the SBA Watershed Protection Program include developing a Watershed Management Program for the SBA system, including Lake Del Valle and Bethany Reservoir, and protecting local drinking water and water resources from identified contaminant sources (e.g., septic tanks) for urban, agricultural, recreational, and environmental uses.

4.2.1.2 Groundwater
The groundwater supply from the Livermore-Amador Valley Main Basin is generally consistent in mineral quality, whereas the surface water supply can see large deviations in the quality of water due to high and low surface water runoff and algae blooms. Zone 7 plans to augment its ability to recharge the Main Basin to maintain higher levels of local storage and allow for more pumping when necessary, which will improve both water supply reliability and salt management.

Zone 7 plans to build an additional demineralization facility to continue to decrease the salt content of the Main Basin. Finally, Zone 7 is managing chromium-6 levels in groundwater through blending, with consideration of treatment facilities in the future, if required.

4.2.1.3 Arroyo Valle
Historically, access to Zone 7’s stored water in Lake Del Valle has not been problematic, unless there is an outage on the Del Valle Branch pipeline. Zone 7 closely coordinates use of Arroyo Valle water with DWR. Water collected from the local watershed is protected under the SBA Watershed Protection Program Plan. In general, the water quality of Arroyo Valle runoff is good, and does not affect the reliability of this water supply; however, as noted above, taste and odor can also affect supplies from Lake Del Valle. Algal blooms in the lake can also reduce production capacities.

4.2.1.4 Byron Bethany Irrigation District
Zone 7’s other imported surface water supply, transfer water from BBID, is also linked to the Delta and SWP facilities. This exchange water is diverted from the Delta and delivered to Zone 7 via the SBA. Consequently, the conveyance challenges related to possible shutdown of Delta pumping due to a facility outage, levee failure, earthquake, water quality (e.g., salinity intrusion), and fish impacts apply to the BBID transfer water. Physical limitations in the SWP conveyance capacity could also affect delivery of this supply. These conveyance issues should be addressed by the Delta Conveyance Project. Curtailment of BBID’s pre-1914 water rights during extremely dry hydrologic conditions (like in 2020) also affects the availability of this supply.

4.2.1.5 Local Storage
Zone 7 has three options for local storage: Lake Del Valle, the Main Groundwater Basin, and, in the future, the Chain of Lakes (COLs). The key constraint on the use of the Chain of Lakes for storage is the duration of mining activities, which affects when the remainder of the Chain of Lakes will be transferred to Zone 7 ownership and how much storage is available over time.

Zone 7 continues to work closely with the mining companies and quarry operators so planning efforts can be coordinated.

4.2.1.6 Non-Local Storage
Access to banked water in Semitropic Water Storage District (Semitropic) and Cawelo Water District (Cawelo), both located downstream of Zone 7, requires exchange/s with other SWP contractors located south of Kern County. There must be sufficient water flowing through the Delta to facilitate these exchanges, which could be a challenging condition to meet during a drought. Furthermore, the banked water must be conveyed through the Delta, rendering this supply susceptible to the Delta disruptions. Zone 7 will continue to coordinate closely with DWR, other SWP contractors, Semitropic, and Cawelo to ensure the future reliability of the banked water supplies.

Some of Semitropic’s wells are affected by arsenic. This is currently being managed through treatment before the affected groundwater water is pumped into the California Aqueduct.

4.3 Transfers, Exchanges, and Groundwater Banking
Programs
The City’s LMW system has the opportunity for short-term, emergency water transfers through interties with the California Water Service Company, the City of Pleasanton, and the Dublin San Ramon Services District. During an emergency, the City’s municipal water service area could receive small amounts of water from that intertie. However, the intertie has historically been used for the City of Livermore Water to supply water to the Lawrence Livermore National Laboratory during planned, temporary interruptions of the SFPUC system.

The Livermore Municipal Water system has only limited opportunities for long-term water transfers due to its contract with the Zone 7 Water Agency. Under the current water supply contract, if the City obtains water from another source, it must still pay Zone 7 for the amount of water it would have normally purchased unless the Zone is unable to supply the water. Since

However, should Zone 7 be unable to meet future projected delivery requests, the City would be free to seek transfer agreements or develop other independent water sources.

4.4 Recycled Water and Reuse
The City of Livermore Water Reclamation Plant (LWRP) produces and supplies recycled water to Livermore Municipal Water. Additional details about recycled water are available in Section 5:

Recycled Water and Reuse.

4.5 Local Surface Water
The City of Livermore does not self-supply surface water to meet any water demands of the municipal water service area. The City does receive surface water supplies from Zone 7 as part of the overall supply purchased for the service area.

4.6 Groundwater
The City of Livermore does not pump groundwater to meet any water demands of the municipal water service area. While the City does retain a small pumping quota of about 30 acre-feet per year from the Livermore-Amador Valley Main Basin, it is unlikely that it would be used during the 20-year planning horizon. The City does receive groundwater from wholesaler Zone 7 as part of the overall supply purchased from Zone 7.

4.7 Planned Water Supply Projects and Programs
The City has no planned projects to increase its independent water supply during the UWMP planning horizon. However, some future projects by Zone 7 as reported in the Zone 7 2025 UWMP may expand supplies available to LMW. These projects by Zone 7 are summarized in Table 4-5. DWR Table 6-7 R for LWM is the same as Zone 7’s DWR Table 6-7 W.

Projects are taken from the Zone 7 2025 UWMP. These projects are in the conceptual or planning stages. Zone 7 is participated in the planning efforts of these potential future water supply and/or storage projects to evaluate their benefits, including water supply yield. Implementation of these projects has not been approved by the Zone 7 Board but it is expected that a subset of these projects will be needed to meet future water demands and increase the reliability of Zone 7's system. The partners listed above are potential partners; final participation will be determined when the project has been approved by the respective agencies' governing boards. The 'expected increase in water supply...' are estimates at this time and may need to be adjusted when a final project has been approved. The 'planned implementation year' may also vary depending on project progress.

Zone 7’s imported water supplies have decreased in reliability over the years as SWP reliability has declined. Zone 7’s 2016 Water Supply Evaluation Update (WSE) examined water supply alternatives and potential future supply projects that may increase water supply reliability and meet demand growth. Zone 7 expects that a portfolio of these alternatives will be needed to meet future supply shortfalls including the Delta Conveyance Project, potable reuse options, and desalination. Zone 7’s WSE Update includes new facilities or projects that may reduce the risk of water supply shortages during drought or other temporary unplanned emergency conditions including a reliability intertie with another major water agency such as EBMUD or SFPUC, Chain of Lakes pipeline from Cope Lake to the Del Valle Water Treatment Plant, Los Vaqueros Emergency / Drought storage, and new wells.

Tables 7-12 through 7-18 (DWR Table 7-2 through 7-4 Wholesale) of the 2025 Zone 7 UWMP shows the anticipated new supply for the 2025-2045 Planning Horizons in Normal, Single-Dry and Multiple Dry years; the table has been excerpted and is shown below3 in Section 4.8.

In addition to these new supply options, Zone 7 is also participating in efforts to develop a Delta Conveyance Project and examining policies and operational practices for local groundwater and surface water storage to protect and maximize existing supplies. Therefore, the City’s LMW system will meet future demands in its service area through a combination of new local water supply projects such as regional desalination and potable reuse, the statewide Delta Conveyance Project, enhanced operation of existing surface and groundwater storage, and demand reductions required by the Water Conservation Bill of 2009.

4.8 Anticipated Water Supply Sources in Normal, Single Dry, and Multiple Dry 5-Year Droughts Years
Table 4-6, Table 4-7, and Table 4-8 present the potable water supply anticipated to be available to the City from Zone 7 in average/normal, single dry, and multiple dry years. In Chapter 7 of its 2025 UWMP, Zone 7 has indicated it can meet retailer demands during five-year droughts beginning in 2025, 2030, 2035, and 2040. However, if a drought happens five years in a row starting in 2045 or 2050, during the last year of each drought duration, there will be 14% and 20% shortfall, respectively. The shortfall doesn't consider active water conservation meaning all retailers can fill the gap by conserving water if they work together.

4.9 Climate Change Impacts
Since the SWP is the main source of Zone 7’s water supplies to LMW and other agencies, climate change impacts to the SWP will significantly impact Zone 7 and LMW. Supplies derived from the SWP, including Table A deliveries, groundwater (stored SWP water), and SWP carryover represent about 90% of Zone 7’s 2025 supplies available to their retailers. This percentage remains high, with SWP-derived supplies compromising approximately 41% of Zone 7’s total supplies in 2050. The scenarios in the Draft 2025 DCR that were used for Zone 7’s future supply projections account for climate change impacts based on 2043 emissions level and 15 cm of sea level rise; therefore, these impacts have been incorporated into Zone 7’s water supply planning efforts.

Zone 7 has also evaluated the impacts of climate change to local water supplies (SWP, Arroyo Valle, Main Basin) for the 2022 WSE Update, which incorporates a more conservative risk- based analysis; as downscaling of climate change data is refined further, local climate change impacts will continue to be incorporated in future UWMPs and other planning efforts.

4.10 Embedded Energy
The energy intensity to provide water service to LMW’s customers over a one-year period is presented in this section to the extent that information is available. This includes the amount of energy consumed at LMW’s pump stations within their distribution system.

Water energy intensity is the total amount of energy, calculated on a whole-system basis, used to deliver water to LMW’s customers for use. Energy intensity is the total amount of energy in kilowatt-hours (kWh) expended on a per MG basis to take water from source to point of delivery.

Understanding the whole-system energy intensity would allow LMW to make the following water supply management and system operation strategies:
 Identifying energy saving opportunities as energy consumption is often a large portion of the cost of delivering water
 Calculating energy savings associated with water conservation programs  Identifying potential opportunities for receiving energy efficiency funding or water conservation programs
 Informing climate change mitigation strategies
 Benchmarking energy use and comparing energy use among similar agencies Energy intensity for LMW is calculated for the time period during which Zone 7 deliveries to LMW and electricity usage from PG&E for LMW’s pump stations were both available (November 2024 through October 2025). As shown in Table 4-9, the total energy intensity for LMW’s water distribution system is approximately 621.3 kWh/MG.

5.1 Recycled Water Planning
Municipal recycled water is municipal wastewater that has been treated to a specified quality to be reused for a beneficial purpose and is used to offset potable water demand. For purposes of this UWMP, “recycled water” means only the municipal recycled water, which is water that has been treated and discharged from a municipal wastewater facility.

There are currently excellent opportunities to meet significant portions of the LMW service area demands with recycled water. The Livermore Water Reclamation Plant (LWRP) has been producing and distributing recycled water that meets Title 22 disinfected tertiary recycled water requirements for beneficial use and in accordance with the Regional Water Quality Control Board (RWQCB) permit since 1966. The City has a well-developed recycled water program that currently distributes an average of about 1.8 million gallons of recycled water per day (MGD), with a peak demand of almost 3.3 million MGD.

The City updated its Recycled Water Master Plan in 2013. Additionally, Kennedy/Jenks completed a recycled water white paper report for the City in 2023. The plan identified a number of potential projects to extend recycled water infrastructure to large water users throughout the LMW service area. Due to the high infrastructure cost associated with a dual distribution system, the City chose to continue to expand the use of recycled water in its Recycled Water Use Area (currently only Zone 1 of the LMW service area), to sell a small amount of recycled water to the City of Pleasanton, and to retain the rest of the existing recycled water production capacity for water supply uncertainty. Currently, approximately 50% of recycled water produced is used in the LMW service area or sold to the City of Pleasanton, and the remainder is used in the Livermore Water Reclamation Plant.

Recycled Water Coordination
The Livermore Water Reclamation Plant treats all wastewater collected within the city limits of Livermore. This includes the entire LMW service area and the Cal Water service area. By agreement, the Plant also treats wastewater from the Ruby Hills area which is located in the City of Pleasanton. Treated wastewater transport out of the area is handled through the Livermore Amador Valley Water Management Agency (LAVWMA), a joint powers authority (JPA) composed of Dublin San Ramon Services District, City of Livermore, and City of Pleasanton. Since 1979 LAVWMA has owned the conveyance facilities that transport treated wastewater from the LWRP over the Dublin grade, and eventually to the East Bay Dischargers Authority system, which dechlorinates the effluent and discharges it through a deep-water pipeline into the San Francisco Bay.

Recognizing that recycled water is an important part of a complete water resource management program for the Livermore-Amador Valley, water wholesaler Zone 7 is incorporating its use in future water supply planning. Plans for water recycling within the Tri-Valley is coordinated amongst Zone 7, the Retailers, the wastewater/recycled water agencies (City of Livermore and DSRSD), the regulatory agencies such as the Division of Drinking Water and the Regional Water Quality Control Board (RWQCB), and planning agencies such as the City of Livermore

Zone 7, as the groundwater management agency, works to manage salt loading in the Main Basin. City of Livermore Water is currently working with Zone 7 and other Retailers to explore the feasibility of potable reuse in the Tri- Valley area.

In 2023, Kennedy/Jenks Consultants conducted a study on behalf of LMW to predict the City’s ability to provide water to recycled water to customers outside their current service area based on requests from the Lawrence Livermore National Laboratory (LLNL), Tri-Valley Partners and the Dublin San Ramon Services District (DSRSD).

The study concluded that although the City may be able to supply recycled water to some of the requests, it is risky for the City to commit to all the requests made given that the requests are mainly for irrigation during the summer.

In 2012, the City of Livermore City Council previously accepted recommendations regarding various planning approaches and policy considerations for using recycled water supplies from LWRP. Recommendations from the Council included:

1. Maximize the sale of recycled water to provide additional revenue and reduce per-unit production costs by expanding recycled water use through the buildout of existing infrastructure within the City’s recycled water use area and pursuing an agreement with the City of Pleasanton to expand recycled water distribution into specific areas of eastern Pleasanton.

2. Reserve production capacity beyond that needed to support buildout of existing infrastructure in the City service area and identified uses within the City of Pleasanton for potential use in meeting future Tri-Valley water demands as in the Zone 7 Water Supply Evaluation.

3. Begin formal discussions with Zone 7 staff regarding potential funding (or capacity reservation in lieu of funding) for future recycled water projects that offset potable water use.

The City decided to continue to follow the Council’s direction to maximize recycled water use with the City of Pleasanton. Further investigation, like a cost-benefit analysis and entering an equitable cost-sharing agreement, will be required before the City commits to sending water to the other Tri-Valley Partners.

5.2 Wastewater Collection and Treatment
The City of Livermore has approximately 300 miles of sanitary sewer lines ranging in size from 6- to 48-inches. Wastewater collected from the City of Livermore, Lawrence Livermore National Laboratory, and the City of Pleasanton’s Ruby Hills housing development, is collected and treated at the City of Livermore Water Reclamation Plant (LWRP) located on the corner of West Jack London Blvd. and Isabel Ave. (State Route 84) in the City of Livermore.

Wastewater is treated using conventional primary and secondary wastewater treatment processes, as well as tertiary treatment to produce recycled water. Table 5-1 shows the amount of wastewater collected and conveyed to the LWRP.

Conventional wastewater treatment processes consist of:
 Primary sedimentation where heavy organic solids are removed from the raw sewage and sent to the solids stabilization and dewatering facilities.  Secondary treatment utilizing the activated sludge process which removes 85% - 95% of the remaining organic material after primary sedimentation.  Disinfection using sodium hypochlorite to reduce the bacteria levels in the secondary effluent prior to disposal.
 Disposal of secondary effluent through the Livermore Amador Valley Water Management Agency (LAVWMA) pipeline.
 Solids stabilization using anaerobic digestion followed by belt pressing for dewatering prior to disposal.

Tertiary treatment for water reclamation consists of:
 Mono-media filters where 95% - 99% of suspended material is removed from secondary effluent.
 Disinfection using ultraviolet light (UV) prior to disposal.

Tertiary treated effluent meeting California Title 22 requirements for unrestricted water reuse is recycled through landscape irrigation. The tertiary filtration capacity of the LWRP is approximately 8 MGD; however, as of July 2025, the UV disinfection capacity is currently limited to 6 MGD. Based on the current limitations of the UV system, the annual amount of recycled water that could be produced is approximately 2,117. This amount is roughly equal to the actual water demand in 2025, and the projected water demands for 2025-2045 for LMW of Livermore.

Based on the tertiary treatment capacity of the LWRP and the projected water demands, there is opportunity for LMW to continue to offset potable water use with Title 22 recycled water. LMW has begun increasing the capacity of the UV system to match the filter capacity (8 MGD as determined by the most recent filter study) in 2025 and is planned to be completed by Summer 2026.

The last major identified recycled water expansion opportunities were in 2013. The 2013 Recycled Water Master Plan found over 150 potential recycled water customers in the study area which includes LMW and Cal Water service areas. However, the City chose to retain a majority of the remaining recycled water production capacity for a potential future water supply project. The City of Livermore and other Tri-Valley retailers and Zone 7 recently conducted a joint feasibility study to evaluate a potable reuse project. The 2018 Joint Tri-Valley Potable Reuse Technical Feasibility Study concluded that potable reuse for the Tri-Valley was feasible and recommended next steps that included both technical studies and institutional and public outreach to support a potential project. However, project implementation is challenged by several real-life limitations, such as seasonal recycled water availability, economies of scale, and differing opinions on collaboration. Therefore, the wholesaler Zone 7 does not include potable reuse as a future supply.

The LWRP provides disinfected tertiary treated recycled water to the northwestern portion of the City. The distribution system consists of two above ground reservoirs with a holding capacity of

1.88 million gallons each. There are approximately 20 miles of distribution pipeline ranging in size from 4- to 18- inches, with 168 metered connections. There are also 100 recycled water fire hydrants available for contractors to use during construction, and for firefighting and system maintenance. Currently, recycled water is provided for several uses including landscape and agricultural irrigation, fire protection, construction, street sweeping and toilet and urinal flushing.

Below is a map of the distribution system providing recycled water as of 2025.

5.2.1 Current Recycled Water Uses
LMW currently uses UV-disinfected tertiary treated effluent not exceeding a median total coliform value of 2.2 MPN/100 mL for all recycled water uses.

Based on the 2020 UWMP, the projected recycled water use for 2025 was 617 MG. As shown in Table 5-3 (DWR Table 6-5R), the actual 2025 recycled water use was 580 MG, approximately 6% less than the 2020 projection. Approximately 28% of the recycled water supplied by LMW was used for landscape irrigation (unrelated to the golf course), while about 19% was used for irrigation of the Las Positas Municipal Golf Course. Approximately 51% was used as process water at the Livermore Water Reclamation Plant and the Livermore Municipal Airport. The remaining 2% was used for commercial, fire protection and construction uses.

5.2.2 Projected Recycled Water Demand
The potential uses shown below in Table 5-4 (DWR Table 6-4) represent both the projected new facilities planned for the recycled water area as well as retrofitting existing facilities. In most cases it may not be economically feasible for existing developments that are currently using potable water for irrigation to switch to recycled water, nor would it be economically feasible to extend pipelines to serve a small number of customers with limited demands. Projected uses in Table 5-4 (DWR Table 6-4R) are based on the 2025 Zone 7 Water Demand Study. The baseline values were established using the five-year average from 2020 to 2024 for both onsite and offsite applications. Onsite use is projected to remain relatively stable at 0.82 MGD while offsite use is projected to increase by 0.4 MGD in 15 years. Recycled water provided to the City of Pleasanton is used for and reported under the landscape irrigation category.

The recycled water projections are shown in Table 5-4 (DWR Table 6-4R). Projections show an increase in the landscape irrigation category through 2040 (buildout), due to the development of the Isabel Neighborhood, where irrigation is planned to be serviced by recycled water. Industrial recycled water usage is from the Livermore Water Reclamation Plant. A new UV disinfection system will be installed at the plant by 2026. LMW is currently conducting potable reuse studies to guide upcoming recycled water efforts. Additional planning efforts regarding recycled water usage include updates to the recycled water master plan within the next five years.

5.3 Methods to Encourage Recycled Water Use
The primary and most effective action to increase recycled water use in the municipal water service area is the requirement that customers in the designated recycled water use area (LMW Zone 1) must use recycled water for irrigation. This requirement ensures that 100% of new customers in that area use recycled water for irrigation unless they demonstrate a need for potable irrigation. The City first started using recycled water in the early 1960s and was issued its first permit (Water Master Recycling Permit, Order No. 93-159) in December of 1993.

Currently the City’s recycled program is permitted under State General Order WQ-2016-0068- DDW. Since its enactment, the recycled water system has grown to 168 metered connections.

LMW plans to continue this program to expand its recycled water system with the City’s natural growth.

Recycled water rates are determined during the cost of water service study and water rate setting.

LMW will be building a residential recycled water fill station that could serve individual customers with self-hauled water.. There are no current plans to expand recycled water use infrastructure further at this time as shown below in Table 5-5 (DWR Table 6-6R).

Assessment

7.1 Overview
This chapter describes the long-term reliability and vulnerability of LMW’s water supplies, as well as implemented or planned to be implemented water management tools for increasing the reliability of water supplies.

The reliability of the City’s retail potable water supply is subject to its water supply contract with Zone 7 and Zone 7’s water supply reliability policy. Zone 7 has worked with the Tri-Valley water retailers to develop a reliable water system with a variety of supply sources. One of the important factors in developing this system was the Zone 7 Reliability Policy. On October 17, 2012, the Zone 7 Board of Directors approved a revised Water Supply Reliability Policy (Resolution No. 13-4230), which adopts the following level of service goals to guide the management of Zone 7’s treated water supplies as well as its Capital Improvement Program (CIP):
 Goal 1: Zone 7 will meet its treated water customers’ water supply needs, in accordance with Zone 7’s most current Contracts for M&I Water Supply, including existing and projected demands, as specified in Zone 7’s most recent Urban Water Management Plan (UWMP), during normal, average, and drought conditions, as follows:
 At least 85% of M&I water demands 99% of the time.
 100% of M&I water demands 90% of the time.
 Goal 2: Provide sufficient treated water production capacity and infrastructure to meet at least 80% of the maximum month M&I contractual demands should any one of Zone 7’s major supply, production, or transmission facilities experience an extended unplanned outage of at least one week.

In this section, the various supplies of water available to the LMW system through Zone 7 and the City’s LWRP are addressed, along with their respective reliability in a normal water year, a single dry year, and multiple dry years. The base years selected for each scenario have been determined by Zone 7. Since the City’s municipal water supply is directly related to Zone 7, much of the information below has been excerpted from Zone 7’s 2025 UWMP.

7.2 Water Supply Projections
Chapter 7 of the 2025 Zone 7 UWMP discusses projected water supplies which are presented in Section 4.8. The quantity of supply available from each of Zone 7’s water supply sources varies from one year to the next depending on hydrologic conditions. Consequently, Zone 7 reviewed historical data and developed a projected yield for each water supply source under three conditions: (1) normal water year, (2) single-dry year, and (3) multiple-dry years. In accordance with DWR’s 2025 UWMP Guidebook, each condition was defined as follows:

City of Livermore, Water Resources Division
\\kjc.local\kjc-root\kj-office\sfo\projects\pw-proj\2025\2568021.00-livermore 2025 umwp update\09-reports\9.09-reports\working docs\public draft\2025_uwmp-public_draft.docx  Normal Water Year: The year in the historical sequence most closely representing average runoff or allocation levels and patterns. Zone 7 utilized an average of 1922 - 2021 water volume as the representative normal year supply scenario.  Single-Dry Year: The year with the lowest annual runoff or allocation in the historical sequence. Zone 7 utilized 1977 as the representative single dry year supply scenario.  Multiple-Dry Year: The lowest runoff or allocation for a consecutive 5-year period in the historical sequence. Zone 7 utilized 1987-1991 as the representative multiple dry year supply scenario.

LMW’s potable water supply reliability and vulnerability is directly related to seasonal and climatic shortages that impact Zone 7’s water supplies. Therefore, Zone 7’s water supply reliability is used to represent the City’s available supplies during the historic average, single driest year, and driest multi-year period. The projected yield of Zone 7’s water sources under these three scenarios, as reported in Chapter 7 of Zone 7’s 2025 UWMP, indicate that Zone 7 can meet retailer demands during five-year droughts beginning in 2030, 2035, 2040, 2045 and 2050. However, Zone 7 shows in a multiple year drought, there will be a deficit in 2045 and 2050. That deficit is reflected in Table 7-5. Livermore will demand reduction actions to combat this deficit as described in the WSCP.

Zone 7 portion for Normal Years, Single Dry Years, and Multiple Dry Years for their supplies from Table A and the Main Groundwater Basin are quantified in Table 7-1 below. Table A and the Main Basin represent the highest water supply values. The other supplies range from 0 – 6,434 MG. The remaining Table 7-1 tables for Zone 7 can be found in Zone 7 UWMP. These volumes available and % of average supply are provided for context only and are not used in the normal year, single dry year, or multiple-dry year analyses in Tables 7-2, 7-3, 7-4 and 7-5 that follow.

Notes:

Values are based on Zone 7 Table 7-1W for Main Basin water supplies.

7.3 Normal Water Year
Normal Year supplies are anticipated to be as follows:
 Purchased supplies from Zone 7 are assumed to provide 100% of the LMW’S potable water demand.
 About 620 MG of recycled water within its service area in 2030 with a gradual increase to 724 MG by buildout in 2050. The net difference in recycled water supplies is expected to be due to the combined increase in recycled water used for landscape irrigation for the Isabel Neighborhood by 2045.

Normal Year demands have been provided from Zone 7’s projected demands for the City of Livermore. Normal Year supplies provided by Zone 7 shows it can meet all required demands from all retailers including LMW.

As shown in Table 7-3 (DWR Table 7-2R), LMW’s Normal Year supplies are adequate to meet projected Normal Year demands. Surplus water will be retained by Zone 7 for storage or redistribution to other users.

Surplus/(shortfall) 620 672 720 722 724

7.4 Single Dry Year
The single dry year supply is based on 1977 critically dry conditions which is the historically lowest allocation from the State Water Project within the modeling time period of 1922 through 2021. This scenario assumes the worst local conditions with no local water available. Note that

Single Dry Year supplies and demands are anticipated to be as follows:
 Purchased supplies from Zone 7 are assumed to provide 100% of LMW’S potable water demand and recycled water supplies are available to meet demand.  Demands for a single dry year were estimated utilizing Livermore’s percentage of average demand and applying this percentage to projected demand from Zone 7’s DWR Table 7-3.

The single dry year supplies provided by Zone 7 show that it can meet all required demands from all retailers including LMW (Zone 7 DWR Table 7-3W). As shown in Table 7-4 (DWR Table 7-3R), LMW’s Single Dry Year supplies are adequate to meet projected Single Dry Year demands. Surplus water will be retained by Zone 7 for storage or redistribution to other users.

Use totals 2,711 3,031 3,267 3,413 3,360
Surplus/(shortfall) 0 0 0 0 0

7.5 Multiple Dry Years (5 years)
Projected water supplies reflect average output from Zone 7’s water supply risk model, which was initialized given 2025 conditions and configured to simulate a five-consecutive-dry years scenario beginning in each year required in the reliability assessment (e.g., 2030, 2035, etc).

The model ran various trials to reflect varying hydrologic conditions and estimates if Zone 7 can meet all water demands during the five-consecutive-dry year scenario. The five years reflect hydrologic years 1987-1991 period but are randomly shuffled throughout all the trials (i.e., hydrologic year 1988 may not follow 1987 within the five-consecutive-years sequence). Multiple Dry Year supplies and demands are anticipated to be as follows:
 Purchased supplies from Zone 7 are assumed to provide 100% of LMW’s potable water demand and recycled water will be available to meet all non potable demands during the multiple dry-year event.
 Demands for multiple dry years were estimated utilizing Livermore’s percentage of average potable demand and applying this percentage to projected potable demand from Zone 7’s DWR Table 7-4 and adding recycled water demands.

As shown in Table 7-5 (DWR Table 7-4R), Zone 7 can meet all retailers’ demands during five- year droughts beginning in 2025, 2030, 2035, and 2040. However, if a drought happens five years in a row starting in 2045 or 2050, during the last year of each drought duration, there will be 14% and 20% shortfall, respectively. The shortfall doesn't consider active water conservation meaning all retailers can fill the gap by conserving water if they work together.

7.6 State Water Project Reliability
For Zone 7, the 2025 Delivery Capability Report’s (DCR) existing supply condition was assumed to represent 2025 (59 percent Table A reliability, 80,619 AFY4), and the future condition (54 percent Table A reliability, 43,500 AFY4) was applied to 2040; the years in between were interpolated between these two bookends. DWR estimates of SWP supply reliability in its Draft 2025 Delivery Capability Report (DCR) are based on existing facilities, and do not include the proposed DCP. Since Zone 7 UWMP uses DWR’s Draft 2025 DCR to estimate SWP supplies at 2043, any changes in SWP reliability resulting from the proposed DCP are not included. Most recent estimates from DWR indicate that DCP is expected to increase SWP Delta exports by about 467,000 acre-feet per year on a long-term average under current climate conditions.

As a contractor of the SWP, Zone 7 also has access to Article 21 water (interruptible or surplus water) and Article 56d water (turnback pool water). Neither Article 21 nor Article 56d water were included in this UWMP for planning-level purposes.

Additional water is primarily available during dry years under the Yuba Accord, but the amount is relatively small: 400 AF in 2014, approximately 300 AF in 2015, and 3,000 AF in 2020. For planning purposes, Zone 7 currently does not assume any water supply yield specifically from the Yuba Accord, although Zone 7 will continue to pursue this supply when available. Water from the Yuba Accord could contribute to Zone 7’s supply as a water transfer.

7.6.1 Delta Reliability
The instability of the aging levees in the Delta poses a significant concern. These levees are vulnerable to seismic events and the impacts of climate change. Additional challenges include regulatory uncertainty and water quality issues, such as saltwater intrusion. The declining health of the Delta ecosystem further threatens the long-term reliability of the State Water Project (SWP) and the Delta’s water conveyance capability. These issues directly affect the Tri-Valley’s long-term water supply reliability, as most of Zone 7’s supply depends on the Delta and SWP system.

In 2018, DWR published their Delta Flood Emergency Management Plan, which provides strategies for responding to Delta levee failures. This plan includes a strategy to establish an emergency freshwater pathway from the central Delta along Middle River and Victoria Canal to the export pumps in the south Delta. The plan also includes the pre-positioning of emergency construction materials at existing and new stockpile and warehouse sites in the Delta. The plan has found that using pre-positioned stockpiles of rock, sheet pile and other materials, multiple earthquake-generated levee breaches and levee slumping along the freshwater pathway can be repaired in less than six months.

The DWR Delta Levees Subventions and Special Projects Programs have prioritized, funded, and implemented levee improvements along the emergency freshwater pathway and other water supply corridors in the central and south Delta. These efforts are complementary to the Delta Flood Emergency Management Plan, which, along with pre-positioned emergency flood fighting materials, ensures reasonable seismic performance of levees and timely pathway restoration after a severe earthquake.

Furthermore, Zone 7 and other SWP contractors are currently working with DWR and other key stakeholders to address the many complex issues undermining the Delta through the proposed Delta Conveyance Project (DCP).

The Zone 7 Board has approved funding and participation in planning, permitting, and other pre- construction work of the DCP through 2027. The Zone 7 Board has not yet made a decision on whether to participate in construction of the project. For planning purposes, the 2025 UWMP does not include DCP, since it is expected to come online around 2045, near the end of Zone 7’s future planning period.

Continued participation by Zone 7 in the planning efforts will allow Zone 7 to elect to participate in the DCP implementation in the future based on information developed in the planning process, allow access by Zone 7 to information related to benefits and costs, and provide Zone 7 influence throughout the process. The work over the next two to four years will inform the Zone 7 Board’s decision-making as the DCP continues to advance.

In addition to capital projects to improve Delta reliability, Livermore has also utilized water use efficiency and recycled water to limit its reliance on Delta water supplies. Appendix B includes DWR Tables C-1 through C-4 outlining the reduction in reliance on the Delta utilizing 2010 as the base year for comparison. Projected water use efficiency and recycled water use equates to an expected 19% reduction in Delta reliance by the year 2050.

7.7 Regional Supply Reliability
Zone 7 promotes regional supply reliability and reduced reliance on water imports by:
 Evaluating and pursuing new water supply options, including potable reuse and brackish water desalination;
 Supporting the expansion of recycled water use for irrigation;  Working closely with its retailers to implement an active conservation program; and  Optimizing and expanding local storage.

In addition, Zone 7 is a member of the Bay Area Regional Reliability (BARR) partnership, which brings together eight Bay Area water agencies to improve regional water supply reliability. In addition to Zone 7, these agencies include: ACWD, SFPUC, the Bay Area Water Supply and Conservation Agency (BAWSCA), CCWD, EBMUD, Marin Municipal Water District (MMWD), and VW. The BARR partners have agreed to work cooperatively to address water supply reliability concerns and drought preparedness on a mutually beneficial and regionally focused basis. Near- and long-term joint water supply reliability projects may be evaluated through BARR, such as use of the capacity of existing facilities, changes to infrastructure (including new interties, recycled water, water conservation, expanded treatment, regional desalination, and water transfers and exchanges), and other projects or institutional arrangements that encourage a regional approach to achieving water supply reliability in the Bay Area.

7.7.1 Reliability Projects

7.7.1.1 Interties
As part of its existing CIP, Zone 7 is planning to establish a reliability intertie with another major water agency (e.g., EBMUD or SFPUC) to help mitigate some of the risk during a major water supply interruption from the Delta and to create opportunities for transfers/exchanges. This intertie could allow Zone 7 to acquire emergency water supplies to help meet minimum health and safety water supply needs during a major Delta outage, assuming the partnering agency has available supply and the transmission capacity available during the emergency period. A conceptual 24- to 30-inch intertie with EBMUD could connect to the west side of Zone 7’s transmission system and convey up to 10 to 15 MGD of supply. The new Chain of Lakes (COLs) Pipeline would allow for access to water stored locally in the Chain of Lakes. Water would then be accessible to the DVWTP via one of the SBA turnouts.

7.7.1.2 Groundwater Management
Zone 7 continues to study the groundwater basin and develop new tools (e.g., an improved groundwater model) to better understand the levels of groundwater extraction possible under various conditions while maintaining levels above the historical levels that have been reached in certain portions of the Main Basin (“historic lows”). Zone 7 also plans to augment its ability to recharge the Main Basin (e.g., through the COLs) to increase local storage and allow for more pumping when necessary, which will improve both water supply reliability and salt management.

Finally, Zone 7 plans to build additional wells to allow for improved management of groundwater levels, contaminant concerns, and to increase groundwater production capacity during droughts and surface water-related outages. A new booster pump station will improve Zone 7’s ability to convey groundwater throughout Zone 7’s service area and increase production capacity.

7.7.1.3 Demand Management Measures
In early January 2014, Zone 7’s Board of Directors learned that all pumping from the Delta could be stopped due to severe, persistent, and record drought conditions. California Governor Jerry Brown declared a Drought State of Emergency on January 17, 2014 and requested voluntary conservation of 20 percent. For the first time in its history, Zone 7 was facing a potential water supply crisis. Governor Brown subsequently mandated water use reductions in April 2020.

Through an amazing effort by the entire Tri-Valley area, Zone 7 saw a 28.6% reduction in total water demand (treated and untreated) in 2014, and a 40% reduction in total water demand through November 2020.

To minimize the need for imported water, LMW implements the Demand Management Measures (DMMs) described in Section 8 of this UWMP and plans to maintain its efforts to ensure that water resources are used wisely to meet the requirements of the SB X7-7.

7.7.1.4 Recycled Water
Zone 7 and LMW’s source water is affected by limitations related to legal, environmental, water quality, and/or climatic issues. Recycled water supply is also limited by treatment facilities capacity and storage capacity. LMW’s recycled water supply is treated at the LWRP. LMW provides supplemental recycled water as described in Section 5 of this UWMP to offset demands on Zone 7 supplies.

7.7.1.5 Surface Water Management
Zone 7 currently relies on additional incoming surface water supplies from contracts and local water rights, previously stored surface water in the local groundwater basin, and two non-local groundwater banking programs to meet its demands. Zone 7’s WSE Update evaluated water supply alternatives and potential future water supply projects that could be used to make up for the decreased reliability from existing supplies and meet demands from growth.

Within Zone 7’s 2025 UWMP, Zone 7 staff compared projected water supplies during normal, single dry, and multiple dry water years with its customers’ demand scenarios. It should be noted that a portion of the water demand during the normal year includes the storage of water supply for use in dry years. Based on the existing and planned future water supply assumptions made by Zone 7, it is not anticipated that there will be any difficulty in meeting projected Livermore water demands under normal conditions, single dry years, and multiple-dry years.

However, Zone 7 expects that a portfolio of future supply alternatives, including the Delta Conveyance Project, will be needed to meet future supply shortfalls. If the Delta Conveyance Project is delayed, alternative water supplies such as potable reuse or desalination will be needed to meet water supply needs.

7.8 Drought Risk Assessment
In accordance with CWC Section 10612, urban water suppliers must conduct a DRA, which evaluates the risk of a severe drought occurring for the next five consecutive years (2026-2030).

Supply conditions for the DRA are based on the five driest consecutive years on record, with adjustments to consider plausible changes in climate, regulations, and other locally applicable criteria.

The water shortage condition for the DRA is the same as the five-consecutive-dry years drought described in Section 0. The DRA assumes 5, 11, 60, 13, and 25 percent SWP Table A allocations for 2026-2030, respectively. The last four years reflect the last four years of the multiple-dry year scenario previously discussed, based on 2025 values from the 2025 West Yost Water Demand Study. Data for 2026 reflect current projected available supplies. Surplus water is stored for use during subsequent years.
5-year Drought Risk Assessment of LMW supplies and demands is anticipated to be as follows:
 Purchased supplies from Zone 7 are assumed to provide 100% of LMW’S potable water demand and recycled water supplies can meet all non-potable demands.  Supplies for the 5-year Drought Risk Assessment were estimated utilizing Livermore’s percentage of average demand and applying this percentage to available supply from Zone 7’s DWR Table 7-5.
 Demands for the 5-year Drought Risk Assessment were provided from Zone 7’s projected demands for the City of Livermore for water years 2026 through 2030.

As shown in Table 7-6, during a five-year drought beginning in 2026, Zone 7’s supplies are projected to be adequate to meet projected demands through 2030, even without water conservation. Surplus water will be retained by Zone 7 for storage or redistribution to other users.

8.1 Water Conservation Regulations
The purpose of this chapter is to provide a comprehensive description of the LMW’s water conservation programs. The conservation program is implemented to promote conservation, reduce the demand on the water supply, and meet water use reduction targets (pursuant to Section 10608.20) set forth by SB X7-7.

LMW is committed to reducing the demand for potable water through water conservation. The 2020 Use Target was 192 GPCD and the Actual 2020 Water Use was 190 GPCD, thereby meeting the SB X7-7 target as detailed in Section 3 of this UWMP.

In evaluating Demand Management Measures (DMM) implementation, staff considered the intent of the DMM as well as the size and complexity of the City’s municipal water system. Staff has made a concerted effort to implement all measures in the most cost-effective and practical way. Also, the high reliability of the Zone 7 water supply has historically influenced the emphasis the staff has placed on implementing the Demand Management Measures prior to the 2009 Water Conservation Act.

In 2014, the California Water Code was significantly modified by Assembly Bill 2067 to simplify and update the DMM reporting requirements from 14 specific measures to seven more general requirements. This section discusses in detail the implementation as well as any planned enhancements for each of the DMMs to promote conservation and reduce the demand. Funding for conservation programs is provided through water rates.

LMW will continue to monitor the overall effectiveness of its water conservation activities and may implement additional demand reduction measures if further reductions are required by other legislation.

In addition to programs planned and implemented by LMW, LMW and the other three Tri-Valley water retailers, work together with water wholesaler Zone 7 to plan and implement regional programs that promote water conservation and water efficiency. The four Tri-Valley water retailers provide funding and participate in regional programs that are administered or coordinated by wholesaler Zone 7.

DMMs contributed by Zone 7 and LMW will be discussed below, including a summary of the implementation over the past five years and planned implementation to achieve water use targets.

8.2 Demand Management 2020-2025
The purpose of the Demand Management Measures (DMM) section of this UWMP is to (a) provide a description of the past water conservation programs that LMW has implemented since 2020 to meet its urban water use reduction targets and (b) describe the activities and actions LMW plans to use in the future to meet its urban water use reduction targets. Listed below are those DMMs that the UWMP Act and Water Code specifically mention:

8.2.1 Water Waste Prevention Ordinances
A detailed description of LMW water waste prohibition plans and ordinances are provided below. Copies of Water Shortage Contingency Plan, Water Conservation Ordinance (City Municipal Code 13.26), and the Mandatory Drought Conservation Measures Ordinance (City Municipal Code 13.27), are included in Appendix C.

8.2.1.1 Water Shortage Contingency Plan
LMW first adopted a WSCP in 1991 and updated the plan in 1996, 2005, 2011, 2020, and 2025.

The WSCP will be reviewed and updated periodically as necessary to ensure conformance with California Water Code requirements; but at least every 5 years as part of the Urban Water Management Plan update process.

LMW has developed its latest WSCP for the City’s municipal water system in accordance with California Water Code Section 10632(a). The WSCP describes the following required elements for all water users in the service area:
 Water conservation stages of action in response to shortages greater than 50%.  Estimates of the projected 5-year water supply.
 Actions taken to prepare for and implement during catastrophic supply interruptions.  Mandatory prohibitions and consumption reduction methods.  Analysis of potential revenue impacts from Shortage Plan implementation.  Mechanisms for determining water use reductions.

The WSCP includes a variety of voluntary and mandatory management practices to conserve water. The majority of the mandatory conservation practices are triggered at the Stage-3 level; corresponding to an expected reduction of 30% from normal use. Some of the other mandatory prohibitions and the associated stages are described below:
• The use of potable water for municipal activities such as street cleaning will be

Recycled water will be used for these needs in Stage 4 water shortage events, with the exception of water used for sewer line flushing during emergency sanitary sewer blockages or overflows.
 Implementation of irrigation during specific dates and times starting from Stage 1  The use of sprinkler irrigation will be prohibited and the requirement to irrigate by hand- watering only on Saturday or Sunday will become mandatory at the Stage 4 level.  The use of potable water for compaction or dust control during construction activities will be prohibited at the Stage 3 level since recycled water is available for these uses.  The use of potable water for washing buildings, vehicles, or boats except at facilities which capture and recycle the water will become a mandatory prohibition at Stage 4 level.
 The use of potable water for decorative water features such as fountains and limiting water use at restaurants will become a mandatory prohibition at the Stage 5 level.

Below is a table for cross referencing demand management measures from the UWMP to the associated chapter located within the WSCP.

8.2.1.2 Water Conservation Ordinance
The City first adopted a Water Conservation Ordinance in September 2011 adding new Chapter

13.26, Water Conservation to the Livermore Municipal Code to enact conservation measures to address the 20% reduction in per capita water use required by the Water Conservation Bill of 2009 (SB X7-7). The City’s Water Conservation Ordinance established voluntary and mandatory water conservation practices, and best management practices to encourage wise water use, minimize the effect of shortages on LMW’s customers, and to address water supply shortages and required demand reductions. The Water Conservation Ordinance specifies that water waste prohibition is in effect at all times and provides the legal authority to implement water conservation measures and best management practices included in the WSCP. A copy of the Water Conservation Ordinance is included in Appendix C.

8.2.1.3 Mandatory Drought Conservation Measures Ordinance The City first adopted a Mandatory Drought Conservation Measures Urgency Ordinance in May 2014 adding new Chapter 13.27, Mandatory Drought Conservation Measures to the Livermore Municipal Code to prohibit wasteful water practices and maximize the beneficial use of water for residents within the City. The Ordinance acknowledged that there are two water retailers in Livermore, LMW and Cal Water. Both retailers receive a majority of their water from wholesaler Zone 7 Water Agency.

8.2.1.4 Implementation Over the Past 5 Years
LMW has met the SB X7-7 required 20% reduction in demand for 2025 water use as described in Section 3. LMW will continue to utilize the subsequent programs, outreach, and audits to maintain this overall reduction in water use from baseline values. The WSCP, as part of this UWMP, establishes new water shortage stages and associated demand management measures with each stage to assist in achieving demand reduction.

8.2.2 Metering
All water connections are fully metered. Water service in the LMW service area is not allowed without a water meter. This requirement is further strengthened by water wholesaler rules that also do not allow service connections without a meter.

Meter replacement and/or recalibration are evaluated regularly via billing software. Unusual consumption is flagged and checked for accuracy. Meters that are stuck or do not meet accuracy specifications are immediately replaced. Billing accounts with meter failures are assessed an estimated consumption rate that reflects their average usage during the period.

Meters that are 3-inches and larger are proactively tested annually and recalibrated, repaired, or replaced as needed. Additionally, meters are replaced within the system based on their service length with the oldest meters receiving replacement priority as funding and staff availability allows.

8.2.2.1 Implementation Over the Past 5 Years
LMW has completed an upgrade of the existing water distribution system from legacy Touch Read water metering to an Automated Metering System in 2017. The purpose of this project was to encourage water savings by providing customers web access to their real time water use, working with them to identify conservation opportunities, such as ET Controllers, and better evaluating the conservation benefit from these measures.

During the last five years, LMW has been utilizing the City’s Advanced Metering Infrastructure (AMI) to collect near real-time demand data from customer meters, which is then made available to customers via a secure website. The system uses fixed network AMI technology.

The water usage data are shared with customers for their use in identifying water conservation opportunities. Water conservation staff will then work with these customers to identify water conservation strategies, such as fixing leaks, alternative irrigation techniques, and replacing older appliances with new higher efficiency models.

8.2.3 Conservation Pricing
LMW does not use conservation pricing. LMW’s tiered water rates are established for each tier to reflect actual cost differences, not as a penalty for using “too much.” Higher usage costs more to serve due to more expensive water sources, larger infrastructure, additional pumping costs, extra regulatory compliance cost, etc.

In addition to normal water rates and charges, the City adopted “conservation” rates to be used in the event of declared water shortages and periods of mandatory water conservation included in the WSCP. “Conservation” rates are calculated to recover the necessary revenue to continue to fund budgeted water system expenditures based on the expected reduction in water use at each stage of the water shortage contingency plan.

8.2.3.1 Implementation Over the Past 5 Years
In September 2021, Livermore City Council implemented Stage 2, mandating a 15% reduction in water use compared to 2020 levels. These restrictions, including limited landscaping irrigation, were lifted in April 2023.

Reactivation of shortage water rates has not been issued since April 2023. The WSCP, as part of the UWMP, provides mapping for tiered rates as they now correspond to the 6 water shortage stages described in the WSCP.

8.2.4 Public Education and Outreach
Table 8-2 below briefly describes communication protocols and outreach programs already in practice by Zone 7 and LMW. These programs, along with public information campaigns, have successfully reduced water consumption during past drought events.

8.2.4.1.2 Water Efficient Landscaping Lawn Conversion Rebate Program LMW and other Tri-Valley water retailers participate in the Water Efficient Landscaping Lawn Conversion Program administered by Zone 7.

The program was revamped in 2025 by including a $2 per square foot incentive for lawn conversions. Lawn conversion rebate applications are submitted to Zone 7 for processing.

Applications must include (1) a detailed list of proposed plants, (2) an aerial drawing on grid paper to show the project measurements, (3) a picture of the lawn area that will be converted, and (4) proof of HOA approval, if necessary.

Implementation Over the Past 5 Years
LMW continues to offer this rebate program for its customers. This rebate program is very time consuming for both staff and the applicant, so Zone 7 and LMW are working to streamline the process further.

8.2.4.1.3 Weather-Based Irrigation Controller (WBIC) Rebate Program Since 2011, LMW and other Tri-Valley water retailers have participated in the Weather-Based Irrigation Controller (WBIC) Rebate Program administered by Zone 7. WBICs reduce water use and runoff from overirrigation, which can carry excess fertilizers, herbicides, and pesticides into local waterways. They accomplish this by automatically adjusting irrigation schedules in response to local weather data and soil moisture measurements.

WBIC rebate applications are submitted to Zone 7 for processing. Along with the application, participants must include (1) a copy of the WBIC receipt, (2) a picture of the installed WBIC, and (3) a screenshot of their irrigation schedule.

Implementation Over the Past 5 Years
LMW continues to offer this rebate program for its customers.

8.2.4.1.4 Greywater System Rebate
LWM provides a rebate for customers to install laundry-to-landscape greywater systems so that customers can have a reliable supply of water for their plants during water shortages or droughts. Customers must submit their application to LMW for processing along with their copies of their receipts and photos of their landscaping and laundry machine.

8.2.4.1.5 Pool Cover Rebate
LMW provides a rebate for customers who install pool covers. Pool covers reduce pool water evaporation by 95% reducing water needed to fill pools. Customers must submit applications to LMW for processing within 60 days of purchasing their pool cover. The pool cover must cover at least 75% of their pool surface. The application must accompany a copy of their receipt and a photo of the installed pool cover.

8.2.4.2 Water Use Audit Programs

8.2.4.2.1 Residential Water Survey and Conservation Check-up Program The LMW Residential Water Survey and Conservation Check-up Program was initiated in 2011.

The program was initiated either by a call from the customer or when staff noticed an unusual increase in historic usage or a consistent pattern of excessively high usage in their daily activities through utility billing and usage reports. The customer was contacted to alert them of the elevated usage and to assist the customer in identifying areas of water savings and potential leaks. The customer was also provided a free water conservation kit.

While some customer service calls were initiated by staff, a majority of the customer service appointments were driven by calls from customers. The program included documentation of customer service calls, including standardized reports on leak repairs or recommendations, but did not include documentation and follow-up to determine if conservation measures were implemented to reduce consumption.

Implementation Over the Past 5 Years
In 2019, LMW eliminated its water meter reader positions with implementation of AMI and ended this program. However, City staff now provide free water conservations kits for single- family residential customers as appropriate. The kits feature a range of water-saving plumbing retrofit fixtures to help make conserving water for customers easier.

8.2.4.3 Water Conservation Outreach Methods

8.2.4.3.1 Utility Billing Software
As of 2025, there are 10,923 metered connections (residential, multi- family, commercial, irrigation, recycled and institutional). Water bills are made available to customers in hard copy and electronic formats which they can pay in a variety of ways including online.

Implementation Over the Past 5 Years
Since 2017, LMW has implemented an automated meter infrastructure system by Sensus. This system takes and transmits hourly readings of consumption (in 6-hour packages) which allows customers to self-serve with alerts, usage history, and more features to help manage their water use and quickly fix leaks. This system also helps water distribution operators locate potential meter problems and address them in an efficient and prompt manner.

Tracking water savings identified through use of the utility billing software has not been conducted to date.

8.2.4.3.2 Monthly Billings
LMW began using its monthly water bills to educate customers about their water use and conservation in 1991. Each bill shows their water use for the month compared to their water use during the same month of the previous year. Additionally, reminders are placed on customer’s bills that include, but are not limited to, resetting sprinklers in the winter or simply turning off all outdoor irrigation.

Customers can see the impact of wasted water much sooner with monthly billings than bimonthly or flat rate billings and act more swiftly to identify and correct any problems.

Implementation Over the Past 5 Years
In 2018, LMW launched the “Love My Water” customer portal using the automated metering infrastructure system by Sensus. This portal allows customers to monitor their water use in real- time and set up automatic leak alerts. Historical water usage comparisons and water conservation reminders are still printed on water bills.

8.2.4.3.3 Websites
LMW and the other Tri-Valley water agencies administer or contribute content related to water conservation on the following websites:

City of Livermore Water Resources Division Website (www.livermoreca.gov/wrd) The City of Livermore’s Water Resources Division website is regularly updated with events, conservation messaging, and conservation actions.

Tri-Valley Water-Wise Gardening Website (www.trivalleywaterwise.com) In 2005, the Tri-Valley Water Conservation Group worked with a software firm to develop a CD--ROM that provided Tri-Valley-specific information on water-wise gardening. The CD-ROM was financed by the Tri-Valley water retailers through Zone 7. The CD-ROM, distributed by Zone 7 and the Tri-Valley water retailers, provided homeowners with information on how to establish landscaping that is water efficient based on climate and other factors specific to the Tri-Valley region. Educational content that was historically available on the CD-ROM is now available on the website under the “resources” tab.

Tri-Valley Water Website (www.trivalleywater.org)
During the drought, the Tri-Valley water agencies developed a joint website (www.trivalleydrought.org) to promote water conservation. The website was transitioned to www.trivalleywater.org after the drought ended to serve as a resource to learn about the Tri- Valley’s water supply.

Implementation Over the Past 5 Years
www.livermoreca.gov: LMW continues to update the website as new resources become available.

Trivalleywaterwise.com: LMW continues to update the website as new resources become available.

Trivalleywater.org: During the past 5 years this website was primarily used for residents and organizations to request a “Tri-Valley 101” presentation.

8.2.4.3.4 Social Media
LMW regularly posts water conservation-related information on the following social media accounts:
 City of Livermore Facebook page (@CityofLivermore)
 City of Livermore Nextdoor account
 City of Livermore Instagram page (@CityofLivermore)
Implementation Over the Past 5 Years
The City of Livermore has grown its social media platforms over the past 5 years in order to reach a broader section of the community. As of December 2025, this was the number of followers for each account:
 Facebook: 11,154 followers
 Nextdoor: 25,903 members
 Instagram: 8,963 followers

8.2.4.3.5 Print and Email Newsletters
Since 2016, the City of Livermore has mailed a community newsletter to all property addresses 2 to 4 times a year. Water conservation messaging is often included in these printed newsletters. In addition to these efforts, the City also sends several electronic newsletters to LMW customers each year which include information about water quality, operations and maintenance efforts, and conservation measures.

Implementation Over the Past 5 Years
The City has continued to distribute community newsletters.

8.2.4.4 Overall 5-Year Implementation
In 2025, LMW has been encouraging water reduction through enhanced rebates and continues to encourage customers to conserve water to ensure long-term sustainability. The City will continue to review public outreach programs and their effects on water conservation when tiered water rates are not being utilized.

8.2.5 Programs to Assess and Manage Distribution System Real Loss
LMW conducts monthly water audits to determine water loss that may be due to distribution system leaks. Since 1990, staff has routinely monitored the monthly water purchases and the monthly water sales in order to quickly detect any system irregularities or excessive water loss.

Staff also tracks un-accounted for water from activities such as system flushing, fire flow testing, and water quality corrections.

The most recent survey was completed in 2022 utilizing synthetic aperture radar satellite surveys and localized acoustic detection methods. Several leaks were identified and repaired following the most recent survey.

The average amount of unaccounted for water for the 2020 through 2024 period equaled only 200 MG.

In 2025, in collaboration with Zone 7, LMW introduced the Water Wise Wendy Fix-A-Leak Challenge to encourage residents to detect leaks and avoid water loss. Additionally, businesses are encouraged to use advanced leak detection methods, like acoustic listening devices and thermal cameras, to identity hidden leaks in plumbing and irrigation systems. The City continues to invest in infrastructure to reduce water loss from pipelines.

8.2.6 Water Conservation Program Coordination and Staffing Support
City staff actively participates in the Tri-Valley Water Conservation Group, which consists of staff from all four Tri-Valley water retailers and water wholesaler Zone 7. The Tri-Valley Water Conservation Group (Group) was formed in the late 1980’s. This group meets quarterly to coordinate regional outreach for a variety of regional public outreach efforts. Some of these efforts include periodic advertising, general water conservation information, landscape water conservation media campaigns, water conservation rebate programs, website resources, social media campaigns, coordination of booths and displays at public events and public service announcements. Most of the advertising and materials are prepared and distributed by Zone 7 after group review and comment. Funding is provided by the Tri-Valley water retailers.

The key staff responsible for the City’s conservation program are Water Resources Division Manager, Water Distribution Manager, Technical Programs Manager, and Communications Analyst. Their responsibilities include management, planning, tracking, implementation, and evaluation of the program.

Their duties also include enacting, enforcing, supporting legislation, regulations, ordinances, or terms of service related to water waste prevention. This includes landscape and irrigation inefficiencies, non-recirculating decorative water fountains, and water shortage measures for new development and existing users. Additional duties include coordination and oversight of conservation programs, joint programs with Zone 7, Tri-Valley water retailers, and other outside agencies. This coordination and oversight include communication of water conservation issues to the public, preparation and submittal of reports to various parties, and preparation and updates of the water conservation plan. These activities are supported through coordination and execution of the Demand Management Measures.

8.2.7 Other Demand Management Measures

8.2.7.1 Residential Recycled Water Program
In addition to the DMMs described above, the City of Livermore implemented the Residential Recycled Water Program during the drought.

Recycled water was made available so Livermore residents could supplement their potable water landscape irrigation to keep plants alive if needed during the warm summer months. In 2014, Livermore provided 73 permittees approximately one (1) AF of recycled water. In 2015, interest in the Residential Recycled Water Program increased more than 1,200% from the previous year resulting in Livermore providing 15 AF of recycled water to 898 permittees.

The City also implemented a temporary recycled water fill station for the most recent drought in 2022. The City will be constructing a permanent, automated recycled water fill station at the LWRP which will be available for use in CY2027.

8.2.7.2 Water Wise Gardening Program
LMW and the other Tri-Valley water retailer’s support and fund the Water-Wise Gardening Program that is administered by water wholesaler Zone 7 as detailed in Section 8.2.4.3.3.

In 2008, instead of continuing to hand out CD-ROMs, LMW supported the Tri-Valley Water Conservation Group’s decision to go to a web-based format of the “Water-Wise Gardening” information as a means of reducing program costs and maintaining updated information as available. The site additionally helps visitors to design a landscape, includes photographs, a searchable plant database, and water saving tips. Water customers can access the recently updated “Water-Wise Gardening” information through the City of Livermore website at no cost.

8.2.7.3 Youth Programs
The City of Livermore and the other Tri-Valley water retailers’ support and fund the regional K-12th grade water education program administered by Zone 7’s contractor. The program was implemented in 2002 and is offered to all schools in the Tri-Valley. Educational materials and course outlines used by Zone 7 in classroom presentations have been developed in accordance with California curriculum standards and are grade appropriate. LMW also presents science focused awards and schools.

In addition to the regional program, City staff provide tours of the City of Livermore Water Reclamation Plant.

8.3 Planned DMMs to Reach Water Use Targets
No additional DMMS are planned at this time as the DMMs currently in use are achieving current water use targets.

As part of LMW’s Water Distribution System Risk and Resilience Assessment (RRA), The City of Livermore evaluated seismic risk to water facilities and identified mitigation measures to lessen the risk. This plan meets the requirements of the federal Disaster Mitigation Act of 2000 as well as the requirements of Water Code Section 10644.

From the LMW 2024 Local Hazard Mitigation Plan (LHMP), Livermore is between the Calaveras and Greenville faults. Per the United States Geologic Survey’s (USGS’s) 2007 projections, Livermore has approximately 10-20 percent chance of sustaining a rupture with a magnitude of M≥6.7 over 30 years. From another figure in the same report, that corresponds to a 0.1-1% [0.44% for Calaveras Fault] 5-year probability of the event. The Livermore area has a chance of an earthquake with M≥6.7 of approximately 7.4% over 30 years, or an annual likelihood per year of 0.0025.

9.1 Pipelines
In order to minimize the impact of peak ground acceleration (PGA) of 0.4-1.1g during a seismic event, the LMW is looking for options to replace larger rigid pipes (>= 12 inches in diameter) with flexible pipes. The pipe replacement will be carried out through the City’s long-term water system renewal and replacement program. Replacing aging rigid pipes (e.g. cast-iron pipes and asbestos-cement pipes) will bring the following benefits:
 Decreases the susceptibility of the system to breaks and leaks with ground movement:

Increases robustness of the system.
 Reduces susceptibility to other threats like corrosion: Increases flexibility of system to a range of threats.
 When flexible pipelines are in place, the trunk system will ensure the system is brought back online as quickly as possible: Increases the responsiveness to this threat.  Once service is restored, flexible pipes are less likely to fail from longer-term stress brought about by minor ground movement: Recovery is enhanced.

9.2 Pump Stations
All LMW’s pump stations that are in use have at least been retrofitted since 1997, bringing them up to current codes and construction for resilience around the Bay Area faults. If the PGA of the pumping equipment exceeds that of the structure, the disabled structure could continue to function, though the structure would require replacement.

9.3 Water Storage Tanks
All water tanks owned by LMW are made of steel which is a flexible material compared to concrete. Three out of four potable water tanks were constructed after 2002, showing

The risk calculation shows that the events that would be sufficient to rupture the tanks were large and had a low chance of occurrence. The tanks are positioned so that even a severe rupture would destroy the tank but would be very unlikely to endanger life. The Doolan tank is about 1,800 feet from a nearby commercial/industrial area. There is adequate landscape to significantly dampen the impact of flows from the tank. One tank at the Altamont tank site was constructed in 1985. The LMW will review the initial design of the Altamont tank for seismic code compliance and conduct retrofit if necessary.

This plan documents the City of Livermore’s Water Shortage Contingency Plan (WSCP) per requirements of the Urban Water Management Act, Section 10632 of the California Water Code.

Livermore Municipal Water (LMW) purchases all treated potable water from Zone 7 Water Agency.

The purpose of this WSCP is to provide guidance if triggering events occur — whether from reduced supply, increased demand, or an emergency declaration — and identify corresponding actions to be taken during the various shortage levels or stages of a water shortage. The plan includes a description of shortage levels or stages which are intended to be fair to all water customers and users while having the least impact on business, employment, and quality of life for residents.

2.1 Overview
Water Code Section 10632(a) requires that every urban water supplier prepare and adopt a Water Shortage Contingency Plan (WSCP) as part of its Urban Water Management Plan (UWMP). While the WSCP is a stand-alone document, it is updated and adopted in concert with the UWMP. Contents of the WSCP are informed by the analysis of water supply reliability conducted pursuant to Water Code Section 10635 (contained in the UWMP). The reliability analysis of the UWMP considers “normal”, “single-dry”, and “5-year drought” scenarios. The analysis in the UWMP documents reflects that LMW has sufficient supply to meet normal and dry-year demands except for a couple of drought conditions that can occur in 2045 and 2050.

An area of overlap between the UWMP and WSCP is a new requirement to prepare a Drought Risk Assessment (DRA) (Section 7.8 of the 2025 UWMP) to account for the significant duration of recent California droughts and predictions about hydrological variability attributable to climate change. The DRA is detailed in Section 2.5.

2.2 Water Supplies
As noted earlier, LMW purchases all its potable water supplies from the Zone 7 Water Agency and has no other source of supply. Thus, the water supply assessment and reliability analysis focuses on historical supply from Zone 7 and demands from LMW. The Zone 7 system consists of a variety of different sources. A summary of Zone 7 supplies includes:
• Imported Surface Water
o State Water Project
o Byron Bethany Irrigation District
• Local Surface Water Runoff
o Arroyo Las Positas
o Arroyo Mocho
• Local Storage
o Lake Del Valle
o Chain of Lakes/Groundwater wells
• Non-Local Storage
o Semitropic Water Storage District
o Cawelo Water District

Therefore, Zone 7 is able to balance its supply between a variety of different sources to adapt to shortages or limitations in any one source due to legal, environmental, regulatory, or climatic factors. Traditionally, Zone 7 has been able to supply all the water demands from Livermore even during historical drought conditions. Table 2-1 below provides the Zone 7 supply projections over the planning horizon of this document.

Zone 7 projects that the water agency will have surplus treated water during normal, 1-year drought, and most of the 5-year drought water conditions. However, if a drought happens five years in a row starting in 2045 or 2050, during the last year of each drought duration, there will be 14% and 20% shortfall, respectively. See Zone 7 UWMP for more information.

2.3 Supply Reliability
Zone 7 has provided water system reliability data and supply projections for Water Years 2015 2025 through 2050. Zone 7 projects a reduction in reliance on water from the Delta Watershed, through the application of water use efficiency (WUE), supply exchanges, and alternate water sources. The average projected reduction in watershed reliance in Years 2025 through 2050 is approximately 41%, see Table 2-2 below. According to Zone 7 UWMP DWR Table 6-9 W:

• The non-Delta water supplies include surface water (Arroyo Valle), groundwater (Main Basin), supply from storage (Chain of Lakes Conveyance System, Cawelo Groundwater Banking Program expiring in 2035, and Kern County Groundwater Banking Program), and purchased or imported water (Site Reservoir).

In addition to diversifying water supply, Zone 7 has estimated reductions in water use due to water use efficiency measures. Projected water use efficiency figures (Water Years 2025 through 2050) showed an approximate reduction of 26% in water use when implemented.

These reduction percentages can be met through implementation of WSCP shortage actions discussed further in Section 5 below. See Table 2-3 for projected water use reductions assumed by Zone 7.

Appendix B of the 2025 UWMP includes DWR Tables C-1 through C-4 outlining the reduction in reliance on the Delta. Projected water use efficiency and recycled water use equates to an expected 23% reduction in Delta reliance by the year 2050.

2.4 Demand Projections
LMW staff work closely with Zone 7 each year to provide up to date treated water request estimates for the next 5 years. These estimates are based on historical water use, per capita water use trends and expected changes in land use areas and development within the service area. Water Year 2025 saw a decrease in per capita water use in comparison to previous years which can likely be attributed to the enhanced water conservation initiatives the City has implemented in the last five years. Water use projections developed for Water Years 2026 through 2030 show a decrease in per capita use closer to the baseline values seen in 2022- 2024 and then a linear increase to align with Zone 7 demand projections in 2025. The treated water request estimates prepared by LMW staff may differ slightly from UWMP long-range demand projections because they are based on the historic actual water demand from the prior year. See Section 4 of the Livermore 2025 UWMP for more detailed information concerning projected demands.

2.5 Drought Risk Assessment
The DRA requires suppliers to assess water supply reliability over a 5-year period from 2026 to 2030 that examines water supplies, water uses, and the resulting water supply reliability under a reasonable prediction for five (5) consecutive dry years.

The gross water use values for 2026 -2030 presented in Livermore UWMP Table 2-5 are estimates based on Zone 7’s projected water use for its entire service area. The percentage of LMW’s demand during normal year conditions was utilized to project water uses from Zone 7’s 2025 UWMP Table 7-5 values for the LMW service area. LMW’s total water supplies were projected based on the total available supply to the entirety of Zone 7’s service area adjusted for percentage of water demand from LMW.

Table 2-4 provides a summary of the expected supply and demand scenarios for a 5-year drought condition from 2026-2030. It is expected that Zone 7 will be able to meet all treated water requests during this scenario. Therefore, no Water Shortage Contingency Plan actions are anticipated to be implemented. However, in the case of a shortfall in supply, the use reduction and supply augmentation measures described in Section 5 of this WSCP are available for implementation.

Procedures

California Water Code Division 1, Section 350, states:

“The governing body of a distributor of a public water supply, whether publicly or privately owned and including a mutual water company, shall declare a water shortage emergency condition to prevail within the area served by such distributor whenever it finds and determines that the ordinary demands and requirements of water consumers cannot be satisfied without depleting the water supply of the distributor to the extent that there would be insufficient water for human consumption, sanitation, and fire protection.”

These annual assessment procedures described herein are one tool to be used to determine if a water shortage is to be declared.

New provisions in Water Code Section 10632.1. require that an urban water supplier such as LMW conduct an annual water supply and demand assessment (“Annual Assessment”), on or before July 1 of each year, to be submitted to DWR. An urban water supplier that relies on imported water from the State Water Project (SWP) or the Bureau of Reclamation shall submit its Annual Assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later.

3.1 Timeline and Methodology for Conducting the Annual
Assessment
As described in Section 2.4, LMW staff develops a 5-year treated water request schedule using the current year’s water consumption as a baseline. LMW staff estimates monthly water usage for the next 5 years based on current usage trends and expected new water connections from development within the service area. Projected conservation values are calculated at 10% of average use values for reporting purposes to Zone 7. LMW treated water requests are also compared to Zone 7’s projections to ensure values are similar amongst the agencies. LMW staff presents the 5-year treated water request to Zone 7 in the July timeframe each year (see Table 3-1 below for an approximate timeline). In about January, Zone 7 provides a preliminary treated water request approval by analyzing the initial SWP allocation and determines if this allocation can accommodate the needs of its retailers for the next year.

If it is determined that Zone 7 cannot provide the requested volume of water for LMW, LMW will determine the percentage difference in demand versus supply and will enact a shortage level described in Chapter 4. This can be in conjunction with any demand reductions required by the State of California and/or Zone 7.

In April of each year, Zone 7 finalizes the available water supply to each of its users for the coming year based on SWP allocations and other factors. This final determination informs LMW

Table 3-1 provides targets for performing the Annual Assessment. By starting to plan in June of the previous year, Livermore Municipal Water will get a snapshot of conditions and can start lining up the resources to mitigate supply and start outreach to customers to manage demand.

Major actions are proposed in January, when an initial shortage level is triggered. A final annual assessment is proposed in the May-June current year timeframe.

Table 3-1: Calendar and Methodology for Performing Annual Assessment

3.2 Current Predicted Shortages Based on Annual Water
Supply and Demand Assessment
Although the Annual Assessment must be submitted to DWR on or before July 1 of every year, an early Annual Assessment allows Suppliers and customers to identify uncertainties and prepare financially and logistically for any anticipated water supply constraints in the coming months. Therefore, Suppliers are encouraged to develop procedures, including decision-making processes, that facilitate early analysis and adoption.

LMW does not predict a water supply shortage for the current water year (2025). Anticipated demands are within the planning values presented by Zone 7. Zone 7 has traditionally been able to meet all anticipated demands even during dry conditions. No shortage levels or response actions directly associated with specific shortage levels are anticipated for the current water year.

July LMW submits demands and conservation demands
January
Zone 7 responds to demand projections with available supply and preliminary approval letter

4.1 Water Shortage Event
A water shortage event can be anything from a single occurrence as short as twenty-four hours to a multi-year weather condition. If water shortage event triggers identified in Table 5-1 are met , the City will consider enacting voluntary and/ or mandatory restrictions and other drought response actions as listed in Table 5-2. The drought response actions are targeted primarily at reducing outdoor watering activities. Any such restrictions would be enacted with an adopted resolution passed by the Livermore City Council.

Other events, besides drought, that could trigger a water shortage event include an earthquake, water system failures, fire, contamination, regional power outage, state restrictions or other causes.

4.2 Definition of Drought
The following definition was written by the California Department of Water Resources:

Defining when drought occurs is a function of drought impacts to water users. Drought can best be thought of as a condition of water shortage for a particular user in a particular location. Hydrologic conditions constituting a drought for water users in one location may not constitute a drought for water users in a different part of California or for users with a different water supply. Individual water suppliers may use criteria such as rainfall/runoff, amount of water in storage, or expected supply from a water wholesaler to define their water supply conditions.

Drought is a gradual phenomenon. Although persistent drought may be characterized as an emergency, it differs from typical emergency events. Most natural disasters, such as floods or forest fires, occur relatively rapidly and afford little time for preparing for disaster response.

Droughts occur slowly, over a period of time. There is no universal definition of when a drought begins or ends. Impacts of drought are typically felt first by those most reliant on annual rainfall – ranchers engaged in dryland grazing, rural residents relying on wells in low- yield rock formations, or small water systems lacking a reliable water source. Criteria used to identify statewide drought conditions do not address these localized impacts. Drought impacts increase with the length of a drought, as carry-over supplies in reservoirs are depleted and water levels in groundwater basins decline.

4.3 Natural Disaster or Failure of Water System Facilities In the event of a natural disaster such as an earthquake, fire, toxic spill or flood, or should a catastrophic failure occur at any of LMW's facilities, the City can enact restrictions as described in Table 5-2 of this WSCP. Such restrictions would be based on the varying circumstances as determined necessary and appropriate by the City Council to respond to the emergency conditions, or by the City Manager in the event the City Council cannot act in a timely manner.

4.4 Water Shortage Levels
The definitions below represent the shortage stages originally described in the 2020 Urban Water Management Plan that are consistent with the current Livermore Municipal Code.

Normal Supply
Inclusion of “Normal Supply” in the Plan is an important level. Implementing conservation during “Normal Supply” periods will play an important role in reaching the required twenty percent reduction in per-capita consumption.
• Definition: Water supplies are adequate to meet all the water demands of customers. • Message: We can deliver all the water our customers need, recognizing that customers should practice wise water use at all times.
• Type: Voluntary.
• Expected Reduction: None targeted
• Conservation: Basic water conservation measures and public information promoting wise water use and Best Management Practices when using water for residential, commercial or irrigation uses.

Livermore Stage 1- Minimal Reduction
• Definition: There is sufficient uncertainty concerning water supplies for this year or in the next few years that it would be prudent to conserve local water supplies so that these supplies may be used to meet water demands in the future. • Message: We think we can deliver all the water our customers want but request their help to conserve water to be sure local and imported supplies are adequate to meet future years’ water demands – please conserve.
• Type: Voluntary.
• Expected Reduction: Up to 10%
Livermore Stage 2- Moderate Reduction
• Definition: There are definable events that lead to a reasonable conclusion that in the current and/or upcoming water years, water supplies may not be adequate to meet all customer water demands.
• Message: We may not be able to deliver all the water our customers want, and we need customers’ help to conserve water.
• Type: Voluntary or Mandatory.
• Expected Reduction: up to 20%

• Definition: There are definable events that lead to a firm conclusion that in the current water year, water supplies will not be adequate to meet customers’ water demands. • Message: We cannot deliver all the water our customers need, and we are requiring our customers to use less water.
• Type: Mandatory.
• Expected Reduction: up to 30%
Livermore Stage 4- Severe Reduction
• Definition: A Stage 3 shortage has been in effect, and the reduction goal is not being met, or new definable events require increasing the reduction goal. • Message: We cannot deliver all the water our customers need, and we have not been able to achieve targeted reductions, so we now have to enforce the use of less water. • Type: Mandatory.
• Expected Reduction: up to 40%
Livermore Stage 5- Critical Reduction
• Definition: A Stage 4 shortage has been in effect, and the reduction goal is not being met, or new definable events require increasing the reduction goal. • Message: We cannot deliver all the water our customers need, and we have not been able to achieve targeted reductions, so we now have to enforce the use of less water. • Type: Mandatory.
• Expected Reduction: up to 50%
Livermore Stage 6- Critical Reduction
• Definition: A Stage 5 shortage has been in effect, and the reduction goal is not being met, or new definable events require increasing the reduction goal. • Message: We cannot deliver all the water our customers need, and we have not been able to achieve targeted reductions, so we now have to enforce the use of less water. • Type: Mandatory.
• Expected Reduction: >50%

4.5 Actions to Prepare for Catastrophic Interruption

4.5.1 Emergency Response Plan
This section describes actions taken by the City to prepare for and to be implemented during a catastrophic interruption of water supplies. Potential catastrophic supply interruptions include but are not limited to a regional power outage, earthquake, or other disaster causing a water supply outage such as a failure of the San Joaquin Delta levee system.

The City has developed a comprehensive Emergency Response Plan (ERP) for the Water Resources Division that addresses a variety of potential emergency situations directly affecting the City’s municipal water system. The goals of the ERP are to:

Rapidly restore water service after an emergency;
• Ensure adequate water supply for fire suppression;
• Minimize water system damage;
• Minimize impacts and loss to customers;
• Minimize negative impacts on public health and employee safety; • Provide emergency public information concerning customer service.

The ERP establishes “Action Plans” for different emergency conditions which outline the steps City staff will take to respond to, evaluate, and mitigate the emergency. Action Plans were developed for a variety of water supply interruptions including power outages; earthquakes; flooding; and terrorist events. In addition to Action Plans, the City’s Emergency Response Plan includes an inventory of emergency supplies, mutual aid contacts, and lists of potential vendors of emergency supplies.

The LMW Emergency Response Plan was developed to comply with American Water Infrastructure Act and Section 1433(b) of the Safe Drinking Water Act (SDWA) as amended by the Public Health Security and Bioterrorism Preparedness and Response Act of 2002.

Due to the sensitive nature of the information contained in the Emergency Response Plan, the plan includes an Access Control section that limits distribution of the plan to “individuals directly

Therefore, excerpts from the LMW Emergency Response Plan are not included with this UWMP.

Below is a brief summary of some of the steps staff will implement in response to specific water supply interruptions:

Regional Power Outage – Four of the City’s municipal water system’s five pump stations have emergency generators in the event of regional or local power outage situations. The water telemetry center at the Livermore Water Reclamation Plant also has emergency backup power.

Backup pump station power allows City staff to maintain water service as long as Zone 7 has available water supplies.

Water Supply Outage – After notification by Zone 7 of a regional water supply outage, City staff will immediately put one of the emergency plans into action. If the South Bay Aqueduct (part of State Water Project) were damaged, it is possible that a limited amount of water would be available in the Patterson Pass Treatment Plant forebay and additional water could be taken from Lake Del Valle. If a Zone 7 pipeline were damaged, water could be networked around the Tri-Valley and around the leak through retailer interties. If a City municipal water system pipeline were damaged or leaking, the leak or damaged section could be isolated, and an alternate supply path created through the supply network.

During short-term supply outages, City staff would implement similar procedures described above for power outages. For prolonged, regional outages, City staff would consider the need and feasibility of implementing progressively more aggressive strategies to extend local reservoir supplies. These might include restricting all uses except emergency firefighting, with staff distributing drinking water and portable toilets throughout the service area to meet sanitation and drinking needs. These types of measures would only be considered in the most extreme and prolonged emergency conditions.

Seismic – As part of LMW’s Water Distribution System Risk and Resilience Assessment (RRA), the City of Livermore evaluated seismic risk to water facilities and identified mitigation measures to lessen the risk. This plan meets the requirements of the federal Disaster Mitigation Act of 2000 as well as the requirements of Water Code Section 10644. The 2020 LMW Water Distribution System RRA will be reviewed and recertified by June 2026.

From the LMW 2024 Local Hazard Mitigation Plan, Livermore is between the Calaveras and Greenville faults. Per the United States Geologic Survey’s (USGS’s) 2007 projections, Livermore has approximately 10-20 percent chance of sustaining a rupture with a magnitude of M≥6.7 over 30 years. From another figure in the same report, that corresponds to a 0.1-1% [0.44% for Calaveras Fault] 5-year probability of the event. The Livermore area has a chance of an earthquake with M≥6.7 of approximately 7.4% over 30 years, or an annual likelihood per year of 0.0025.

In order to minimize the impact of peak ground acceleration (PGA) of 0.4-1.1g during a seismic event, the LMW has a countermeasure to replace larger rigid pipes (>= 12 inches in diameter) with flexible pipes. The pipe replacement will be carried out through the City’s long-term water system renewal and replacement program. Replacing aging rigid pipes (e.g. cast-iron pipes and asbestos-cement pipes) will bring the following benefits:

All LMW’s pump stations that are in use have at least been retrofitted since 1997, bringing them up to current codes and construction for resilience around the Bay Area faults. If the PGA of the pumping equipment exceeds that of the structure, the disabled structure could continue to function, though the structure would require replacement.

All water tanks owned by LMW are made of steel which is a flexible material compared to concrete. Three out of four potable water tanks were constructed after 2002, showing compliance with current seismic code. The risk calculation shows that the events that would be sufficient to rupture the tanks were large and had a low chance of occurrence. The tanks are positioned so that even a severe rupture would destroy the tank but would be very unlikely to endanger life. The Doolan Tank is about 1,800 feet from a nearby commercial/industrial area.

There is adequate landscape to significantly dampen the impact of flows from the tank. One tank at the Altamont tank site was constructed in 1985. The LMW will review the initial design of the Altamont tank for seismic code compliance and conduct retrofit if necessary.

The LMW adopted the six-stage water shortage plan in 2020, as outlined in Chapter 13.26 Water Conservation and Chapter 13.27 Mandatory Drought Conservation Measures of Division 1 (Water) of Title 13 (Public Services) of the Livermore Municipal Code. The shortage plan is designed to reduce water demand by more than 50 percent during a severe or extended water shortage event. Livermore has both voluntary and mandatory stages. References to stages from this point forward are to the six shortage levels required by DWR, unless specifically identified.

5.1 Shortage Response Actions
The water shortage conditions in Table 5-1 are based on the Annual Assessment. Other circumstances may also be considered, including but not limited to the time of year, weather forecasts, river flow forecast, rainfall, temperature, past experience and economic feasibility, the volume of water available from Zone 7, and the quality of the water produced from each source.

While each shortage level triggers specific shortage response actions, LMW continues to implement water savings strategies year-round to achieve a baseline demand reduction to assist with desired demand reduction for Zone 7 water agencies. These actions include but are not limited to:
• Baseline public outreach – LMW provides bill stuffers, social media, and web site information pertaining to local drought conditions, local water use restrictions. And water conservation best practices.

5.2 Demand Reduction Actions
When a shortage level is triggered based on the Annual Assessment, shortage response actions are also triggered with the associated shortage level. Table 5-2 describes the response actions and the estimated reduction in demand associated with each action. During the recent 2021-2023 drought, public information messaging which was occurring regionally and statewide was sufficient to achieve the savings needed.

aLivermore's billing software allows them to increase the frequency of account usage reviews to weekly or daily if needed. Outreach is initiated when an account is flagged for high usage. bA Statewide Analysis of Outdoor Water Savings Potential March 2018 Texas Living Waters Project

Livermore’s billing software currently analyzes customer water usage and bills customers on a monthly basis. The City’s AMI software also has the ability to track water usage for customers on a weekly and daily basis if needed during drought conditions. LMW can use this tool to increase frequency of account water usage reviews and to initiate outreach to customers who have higher than normal usage. Billing customers will remain on a monthly basis, but this intermediate means of communication will help curtail water waste in between billing periods.

5.2.1 Customer Demand Reduction
Most of the shortage response actions taken by LMW in the near future will be focused on reducing demand as LMW cannot easily develop supplemental water supply. Each Stage of water shortage has accompanying water reduction measures.

EXHIBIT A
632

DRAFT 2025 Water Shortage Contingency Plan, City of Livermore, Water Resources Division Page 5-4 \\kjc.local\kjc-root\kj-office\sfo\projects\pw-proj\2025\2568021.00-livermore 2025 umwp update\09-reports\9.09-reports\working docs\public draft\2025_wscp_public_draft.docx The City will use a variety of methods to achieve up to more than 50% reduction in water demands in the event of serious supply shortages. One of the most important and earliest strategies will be an expanded public education and outreach campaign during the initial stages of any water shortage.

In addition, the City has conservation rates that correspond to each of the six Livermore Stages identified in the WSCP. The use of Conservation Rates recovers necessary revenue based on the reduced volume of water during water shortages and has the added benefit of encouraging 5% to 10% reduced consumption of water as Conservation Rates increase. For residential users, implementation of Shortage Stage Conservation Rates increases across all rate tiers to send an economic message to conserve water. Livermore Stage 6 Conservation Rates encourage water users to minimize water use by increasing the water rates for an average of

1.9 times of Normal Supply rates.

Each stage shall remain in effect until conditions indicate a more or less restrictive stage is necessary, and action is taken by the City Council based on supply criteria in Error! Reference source not found.. The City Council may enact any stage and need not proceed in order through the stages.

1. Enacting water use restrictions:

Shortage Levels 1-6 of the WSCP shall be enacted by the Livermore City Council declaring an emergency water restriction. Water supply conditions and goals for each restriction stage are outlined in Error! Reference source not found..

2. Modifying and ending water use restrictions:

For each month that customer water use restrictions are in effect at Shortage Level 4, 5, or 6 under this WSCP, the City Manager shall report to the City Council on the status of the shortage and water use changes in the Livermore Water system, including a recommendation to maintain, change or end the water use restrictions. A water shortage event can be terminated by the City Council upon determination that “normal year” supplies have been secured by rainfall, basin replenishment, or a new supply. A water shortage event involving sudden, unforeseen emergencies can be terminated by the City Manager or their designee upon a determination that the emergency no longer exists. As soon as practicably possible or at the next scheduled Council meeting, the City Manager or their designee shall share this termination decision with the City Council.

3. Water Rate Structure:

Water rates will return to the rate structure prior to the water shortage event upon the termination of the event.

5.3 Supply Augmentation Actions
LMW does not contract for additional water sources other than purchasing water directly from Zone 7. Supply augmentation actions in Table 5-3 below represent additional methods to

5.4 Operational Changes
LMW shall comply with the restrictions similar to those implemented for the public to the extent possible. The following actions can be used by LMW as additional measures to limit operational water use within the agency.

• Limit use of potable water to irrigate newly planted street, park and/or golf course trees, street medians, and general irrigation on all LMW properties. No new plantings shall be installed by the City during Livermore Stage 3 or higher Water Shortage Events, unless necessary for erosion control.
• In Livermore Stage 3 or higher, mandatory restrictions, ornamental fountains, and waterfalls shall not be replenished unless water recirculates.

Recycled water will be used for these needs in Livermore Stage 4 water shortage events, with the exception of water used for sewer line flushing during emergency sanitary sewer blockages or overflows.

5.5 Additional Mandatory Prohibitions
The WSCP includes a variety of voluntary and mandatory management practices to conserve water. The majority of the mandatory conservation practices are triggered at the Livermore Stage 2 level; corresponding to an expected reduction of 20% below normal use as shown above in Table 5-1.

5.6 Effectiveness of Shortage Response Actions (by Water Shortage Stage)

5.6.1 Public Information
Without exception, experience has shown that a well-informed public is generally more willing to heed requests to voluntarily conserve or alter water use patterns and will be more likely to comply if mandatory water use restrictions become necessary. DWR (2008) estimates that public information campaigns have alone reduced demand in the range of 5 to 20 percent, depending on the time, money, and effort spent. Public information supports voluntary and mandatory measures by educating and convincing the public that a critical water shortage exists and provides information on how water is used and how they can help. The DWR Drought Guidebook highlights that when the public perceives the drought to be severe, they changed behaviors (such as flushing the toilet less often).

The information provided to the public should include a description of the conditions that will trigger implementation of shortage stages as well as a description of what the plan entails (restrictions, enforcement provisions, etc.). It is also advisable to provide practical “consumer” information that will help water users comply with the plan. For example, information about restrictions on lawn watering might be accompanied with information about proper lawn watering practices.

During the 2014/2015 drought, Livermore Municipal Water customers reduced demand by about 32%, with reductions as high as 42% in many months. City customers achieved this level of reduction based on outreach efforts and warning notices alone, and the staff was not forced to issue fines or penalties to achieve compliance.

5.6.2 Enforcement
A study examining the effectiveness of drought management programs in reducing residential water-use (Virginia Polytechnic Institute 2006) showed considerable variation in the effectiveness of drought management programs and highlighted the importance of public information and enforcement. Results, shown in Table 5-4, indicate that overall reductions in residential water use ranged from 0-7 percent for voluntary restrictions and from 0-22 percent for mandatory restrictions. The observed differences were statistically attributed to information

Source: Virginia Polytechnic Institute 2006

The analysis highlights the key role that public outreach and information plays in the success of drought response actions. Voluntary restriction programs with little to moderate levels of information dissemination had no appreciable effect on water use. Voluntary restriction programs with active promotional efforts, however, reduced water use by an estimated 7 percent from what would have otherwise occurred without any restriction program. Thus, for voluntary restrictions, only the most intense programs had even a moderate level of success in reducing water-use.

Mandatory restriction programs without a significant enforcement component broadly mirrored the outcomes achieved by the voluntary programs. Programs with mandatory restrictions that invested minimal effort in information dissemination did not appreciably reduce residential water use. Programs with no active enforcement efforts but with moderate to high levels of informational dissemination achieved 6 and 12 percent reductions in water use, respectively.

These estimated reductions are similar to those achieved by voluntary programs with aggressive informational campaigns.

The experience LMW had implementing its WSCP and successfully reaching its reduction goals supports the importance of a strong public information program locally, regionally, and statewide. Delivering accurate and timely information to water users, news media and local governments with updates on conditions, restrictions, and helpful contact information is key.

5.6.3 Restrictions on Non-Essential Water Uses
LMW’s Water Shortage Response Actions focuses on public outreach to curtail water waste and non-essential water use. Outdoor water use, including washing sidewalks and watering ornamental landscapes is targeted. These uses are typically considered to be discretionary or nonessential, are highly visible, and therefore relatively easy to monitor, and often are a

636

DRAFT 2025 Water Shortage Contingency Plan, City of Livermore, Water Resources Division Page 5-8 \\kjc.local\kjc-root\kj-office\sfo\projects\pw-proj\2025\2568021.00-livermore 2025 umwp update\09-reports\9.09-reports\working docs\public draft\2025_wscp_public_draft.docx substantial component of water demand, particularly during the summer months when drought conditions are likely most severe.

Given the significance and visibility of lawn watering as the predominant component of seasonal use, best management practices in WSCP typically prescribe time-of-use and other restrictions on lawn watering as described in Section 5.2. This often involves placing water users on a schedule which allows for staggered lawn watering days, as well as restrictions on the times during the day when lawns can be watered.

The American Waterworks Association estimates that voluntary outdoor water use limits can result in a water savings of up to 10 percent and mandatory outdoor water limits can achieve up to a 40 percent reduction in outdoor water use (AWWA 2008).

5.6.4 Drought Surcharge Rates
LMW does not issue drought surcharges, although a conservation rate structure is available as a tool. Zone 7 maintains a drought contingency fund, which is a rate stabilization fund that can be utilized during declared drought events to minimize impacts on water rates as a result of drought conditions. If Zone 7 implements an additional drought surcharge the City would also pass this cost on to ratepayers.

Table 6-1 below briefly describes communication protocols and outreach programs already in practice by Zone 7 and Livermore Municipal Water in coordination with Tri-Valley water retailers.

These programs along with public information campaigns such as shared website, development and distribution of social media, radio advertisements, and newspaper outreach materials, and providing recycled water to residentis for watering landscape have successfully reduced water consumption during past drought events.

The Livermore City Council may enact any stage of the Water Shortage Contingency Plan by adopting a resolution in response to local or regional water supply conditions. The Plan may be enacted based on a number of conditions, including:
• A formal water supply shortage notification by the Zone 7 Water Agency; • A collective recommendation of the Tri-Valley Water Retailers Group; • An actual or potential local water supply restriction or emergency affecting the LMW system;
• A proclamation from the City of Livermore of a local water supply emergency The Livermore City Council may also enact water shortage levels based on guidance from the City and Government notices.

The Conservation Stages will normally be implemented in a progressive manner; however, it may be necessary for the City to skip Stages in the use reduction plan in response to catastrophic supply reductions. In general, conservation/use reduction levels will be set according to the anticipated reduction in available water supplies. The City of Livermore will inform the public of implementation of any water shortage stage and expected water shortages during drought conditions. Information will be disseminated via platforms discussed in Chapter 6: Communication Protocols as well as at City Council meetings when resolutions are adopted.

Actions required by each Stage of the WSCP are cumulative; therefore, if Stage 2 of the Plan is implemented, all the reduction measures in both Stage 1 and Stage 2 shall be implemented.

The priorities for use of available water during shortages, based on Chapter 3 of the California Water Code, are as follows:

1. Health & Safety – interior residential (drinking & sanitation) and fire fighting

2. Commercial, Industrial & Governmental – maintain jobs and economic base

3. Annual Crops – protect jobs

4. Existing Landscaping – especially trees and shrubs

5. New Demands – projects without permits when shortage is declared

Shortages
The stages of action to be undertaken by the urban water supplier in response to water supply shortage have impacts on the LMW’s water revenues and expenses. While expenses will be reduced through lower wholesale water purchases from Zone 7, the decline in expenses does not fully offset the loss in revenue from reduced sales. This is due, in part, to the fact that monthly water rates and charges do not fully recover all of the fixed costs on meter service charges, and instead allocate some fixed charges to the water rate component of the bill. This practice slightly inflates the consumption-based portion of the customer bill to encourage conservation during normal conditions. However, the downside of this practice is that net revenue can decline during water shortages or other periods of reduced water sales.

The impact to net water system revenues will vary with each stage of action and the corresponding level of water shortage and expected conservation. To offset the impacts of water shortages, LMW has developed conservation rates that may be enacted in response to water shortages. Conservation rates are updated and adopted by the Livermore City Council each time normal water rates and service charges are adjusted. By having previously adopted conservation rates, LMW can avoid the delays associated with Proposition 218 notification and ballot procedures prior to implementing conservation rates in response to a water shortage.

These pre-approved rates were essential in maintaining revenues during the 2014/2015 drought and placed LMW in an excellent financial position compared to retailers without pre-approved rates in place. The rates were updated in 2022 from a rate study conducted by ILB Consulting, LLC. See Section 8 of Livermore’s 2025 UWMP for more information concerning conservation water rates.

Conservation rates correspond to each Stage identified in the WSCP and are calculated to recover the necessary revenue based on the reduced volume of water expected to be sold and purchased in each Stage. Currently, Livermore maps the original four stage water rates to the update six shortage levels or stages as part of this WSCP utilizing the crosswalk described in an earlier section. LMW will prepare a cost-of-service study to evaluate these rates in preparation of future drought events and to align conservation rates with the six shortage stages.

9.1 Financial Consequences of Limiting Excessive Water Use Per the California Water Code Section 365 et al., retail water suppliers are required to prohibit or discourage excessive water use as described in Section 7.1. Reporting this is not a required part of the UWMP; however, Water Code Section 10632(a)(8)(C) requires the financial consequences of these actions be reported as part of the UWMP.

Water Code Section 367 states that there are three types of drought emergencies:
• Declared statewide drought emergency
• When a supplier implements its mandatory reductions per their WSCP • A declared local drought emergency

DRAFT 2025 Water Shortage Contingency Plan, City of Livermore, Water Resources Division Page 9-2 \\kjc.local\kjc-root\kj-office\sfo\projects\pw-proj\2025\2568021.00-livermore 2025 umwp update\09-reports\9.09-reports\working docs\public draft\2025_wscp_public_draft.docx This topic is also addressed here in the WSCP because of the relationship between drought emergencies and implementation of the WSCP.

Water Code Section 366 states that a retail water supplier must prohibit excessive use through one of two strategies:
• Rate structure: A rate structure that includes block tiers, water budgets, or rate surcharges over and above base rates for excessive water use by a residential water customer.
• An excessive water use ordinance: An ordinance that includes a procedure to identify and address excessive water use by metered single-family residential customers and customers in multiunit housing complexes in which each unit is individually metered or submetered and may include a process to issue written warnings to a customer and perform a site audit of customer water usage prior to deeming the customer in violation.

In addition to penalties for excessive use described in Section 7.1, LMW also has the option to implement conservation rates that discourage excessive water use. Should a drought emergency occur, LMW would already have the necessary processes in place to discourage excessive use. As discouraging excessive use is already a part of LMW’s actions and because of the conservation rates, the financial consequences of prohibiting excessive use would be minimal.

Additionally, LMW currently monitors customer water usage through its AMI software. The software currently flags high water usage. This allows LMW to track water losses as well as inform customers when usage is encroaching on meeting a conservation rate threshold. LMW uses conservation rates as a method of water consumption reduction and as a method for financial recuperation from lost water sales during drought periods.

10.1 Metering
All water connections are fully metered. Water service in the City’s municipal water service area is not allowed without a water meter. This requirement is further strengthened by water wholesaler rules that also do not allow service connections without a meter. All customer sectors are billed by volume of use at tiered rates.

Meters that are 3-inches and larger are proactively tested annually and recalibrated, repaired or replaced as needed. Additionally, meters are replaced within the system based on their service length with the oldest meters receiving replacement priority as funding allows.

10.2 Monitoring
In normal water supply conditions, purchase and sales data is checked monthly by water staff.

These totals are reported to the Water Resources Manager or the Public Works Director as requested. The totals are also logged into the annual report to the Department of Water Resources.

Shortage Level 1, Shortage Level 2, and Shortage Level 3 Water Shortage:

During Shortage Levels 1-3 water shortage, weekly turnout readings are reported to the Water Distribution Operations Manager. The Operations Manager compares the weekly purchase records to the weekly target to verify that the reduction goal is being met. Weekly reports are forwarded to the Water Resources Division Manager. Monthly summary reports are also sent to the Public Works Director. If reduction goals are not met, the Operations Manager will propose additional activities or conservation measures and advise the Water Resources Division Manager. The Division Manager will notify the Public Works Director that additional corrective actions or use-reduction measures will be implemented.

Shortage Level 4, Shortage Level 5, and Shortage Level 6 Water Shortage:

During Shortage Levels 4-6 water shortage, the procedure listed above will be followed, with the addition of a daily water purchase report being submitted to the Water Resources Division Manager.

Emergency Shortage:

During an Emergency Shortage, a major focus will be on monitoring LMW storage tanks to ensure adequate fire protection and emergency storage. Water staff will review tank levels via the Supervisor Control and Data Acquisition (SCADA) system on an hourly or continuous basis to ensure tank levels are maintained at safe levels for as long as possible. Also, meter readings

Each year, the WSCP will be revisited for completion of the Annual Assessment. This procedure will allow LMW to refine the treated water request estimation procedures to more closely align with the next year’s projected water use. Coordination with Zone 7 will assist in providing a consistently updated document that closely monitors water supply availability.

Adoption of this document will also allow for the WSCP to be updated each year as the service area continues to change in terms of population, land use, climate factors, and other factors.

During the final Annual Assessment report in June/July, any adjustments to the previous year’s WSCP will be discussed and documented for future use within the WSCP.

LMW defines special water features for the purposes of this plan. Features that are supplied by public water from LMW include but are not limited to pools, spas, water fountains, decorative features, and others. DWR defines special water features as those other than pools and spas that could use non-potable water such as recycled water. In LMW, natural water features that do not require public potable water for recreational use such as ponds, lakes, waterfalls, and others do not fall within the special water feature distinction and therefore are not subject to water shortage stage response actions. The intent of this definition is to provide guidance for shortage response actions directed at special water features and to not provide restrictions towards natural water features within the service area.

NOTES:

The values contained in this table/figure are planning level estimates and there is an uncertainty associated with each of these values.” Projects are taken from the Zone 7 2025 UWMP. These projects are in the conceptual or planning stages. Zone 7 is participated in the planning efforts of these potential future water supply and/or storage projects to evaluate their benefits, including water supply yield. Implementation of these projects has not been approved by the Zone 7 Board but it is expected that a subset of these projects will be needed to meet future water demands and increase the reliability of Zone 7's system. The partners listed above are potential partners; final participation will be determined when the project has been approved by the respective agencies' governing boards. The 'expected increase in water supply...' are estimates at this time and may need to be adjusted when a final project has been approved. The 'planned implementation year' may also vary depending on project progress.

Narrative:

The volume of water entering the distribution system was determined based on the monthly volume of water delivered from Zone 7 Water Agency to LMW. The monthly volumes were lined up with the corresponding PG&E electricity bills provided by LMW, which outline
LMW energy consumption is at its distribution system pump stations and metered and billed by PG&E.

CITY COUNCIL STAFF REPORT
ITEM NO. 7.4

DATE:

June 22, 2026
TO:

Honorable Mayor and City Council
FROM:

Carl Brown, Public Works Director
SUBJECT:

Hearing to approve the City's 2025 Water Shortage Contingency Plan.

RECOMMENDED ACTION

At the conclusion of the public hearing, it is recommended that the City Council adopt a resolution:

1 .

Approving the 2025 Water Shortage Contingency Plan.
2 .

Authorize transmittal to the California Department of Water Resources. 3 .

Authorize the City Manager to take appropriate and necessary actions to carry out the purpose and intent of this Resolution and to incorporate any necessary amendments as stipulated and directed by the State Department of Water Resources.

SUMMARY
Staff updated the Livermore Municipal Water (LMW) Water Shortage Contingency Plan (WSCP) pursuant to the Urban Water Management Act, and as specifically required by California Water Code section 10632. The WSCP includes the following major components:

1 .

Water supply reliability analysis over a 5-year period from 2026 to 2030. 2 .

A six-stage categorization of water shortage levels and corresponding demand reduction measures to cover more than 50% of supply shortage.
3 .

Financial consequences of actions during shortages.

Overall, the LMW 2025 WSCP demonstrates that Livermore has a reliable water system over the next five years. In addition, LMW can implement a variety of measures during water shortage stages to reduce water demands.

DISCUSSION
The City of Livermore retained Kennedy/Jenks Consultants, Inc. to update its Water Shortage Contingency Plan (WSCP) per requirements of the Urban Water Management Act, Section 10632 of the California Water Code. The purpose of this WSCP is to identify six stages of water shortage and provide corresponding actions. A summary of the major topics in the current update is presented below. 689

Water Supply Reliability Analysis (Chapter 2)
As stated in the LMW’s 2025 UWMP, the water supply reliability analysis considers “normal”, “single- dry”, and “five-year drought” scenarios. The analysis in the UWMP documents that LMW has sufficient supply to meet normal and dry-year demands through 2050 except for two drought events in 2049 and 2054. The short-term water shortage risk is evaluated through the Drought Risk Assessment (DRA).

The DRA requires suppliers to assess water supply reliability over a five-year period from 2026 to 2030 that examines water supplies, water uses, and the resulting water supply reliability. It is expected that Zone 7 will be able to meet all treated water requests during this scenario. Therefore, no WSCP actions are anticipated to be implemented. In the case of a shortfall in supply, the use reduction and supply augmentation measures described in Chapter 5 of the WSCP are available for implementation.

Annual Water Supply and Demand Assessment Procedures (Chapter 3) New provisions in Water Code Section 10632.1 require that urban water suppliers conduct an annual water supply and demand assessment (“Annual Assessment”), on or before July 1 of each year, to be submitted to the Department of Water Resources (DWR).

Staff presents the five-year treated water request to Zone 7 in the July timeframe each year. Around January, Zone 7 provides a preliminary treated water request response that determines if this allocation can accommodate the needs of its retailers. If it is determined that Zone 7 cannot provide the requested volume of water, staff will determine the percentage difference in demand versus supply, and will request that the City Council enact a shortage stage. This can be in conjunction with any demand reductions required by the State of California and/or Zone 7. In April of each year, Zone 7 finalizes the available water supply to each of its users for the coming year based on State Water Project allocations and other factors. This final determination informs LMW if it is in a shortage scenario, and the results will be reported by LMW to the DWR by July 1st of each year.

Six Standard Water Shortage Stages (Chapter 4)
There are six standard water shortage levels corresponding to progressively increasing estimated shortage conditions (up to 10-, 20-, 30-, 40-, 50- percent, and greater than 50% shortage compared to the normal reliability condition). Besides drought, other events that can trigger a water shortage event are earthquakes, water system failures, fire, contamination, regional power outage, state restrictions, etc.

The Livermore City Council may enact any stage of the Water Shortage Contingency Plan by adopting a resolution in response to local or regional water supply conditions. The Plan may be enacted based on conditions including:

A formal water supply shortage notification by the Zone 7 Water Agency A collective recommendation of the Tri-Valley Water Retailers Group An actual or potential local water supply restriction or emergency affecting the LMW system A proclamation from the City of Livermore declaring a local water supply emergency

Water Shortage Response Actions by Shortage Stage (Chapter 5) The City will use a variety of methods through different stages to achieve more than 50% reduction in water demands. One of the most important and earliest strategies will be an expanded public education and outreach campaign. During past drought events, public information campaigns such as shared websites, development and distribution of social media, radio advertisements, newspaper outreach 690
materials, and providing recycled water to residents for watering landscape have successfully reduced water consumption by more than 30%.

Other demand reduction measures include:

Limit landscape irrigation to specific days and times
Require automatic shut-off hoses
Improve customer usage data review and alerts
Prohibit use of potable water for construction and dust control Require covers for pools and spas
Require commercial kitchens to use pre-rinse spray valves Restrict or prohibit runoff from landscape irrigation
Prohibit use of potable water for washing hard surfaces Prohibit vehicle washing except at facilities using recycled or recirculating water Require swimming pools to be leak proof
Prohibit turf or lawn irrigation
Restrict water use for decorative water features, such as fountains Require restaurants only serve water upon customer request Implement conservation rates

City staff will be able to issue administrative citations to customers violating mandatory prohibitions when necessary, but will provide education before enforcement.

FISCAL AND ADMINISTRATIVE IMPACTS
Adopting this Water Shortage Contingency Plan will not have any new financial impacts on the water enterprise fund as the current “conservation” rates have been designed to capture appropriate funding in years of mandatory conservation measures. Future cost of service studies will further refine “conservation” rates to account for future conditions.

IN THE CITY COUNCIL OF THE CITY OF LIVERMORE, CALIFORNIA

A RESOLUTION APPROVING THE 2025 WATER SHORTAGE

CONTINGENCY PLAN FOR THE LIVERMORE MUNICIPAL WATER

SYSTEM AND AUTHORIZING THE TRANSMITTAL TO THE

CALIFORNIA DEPARTMENT OF WATER RESOURCES

California Water Code section 10632 requires that every urban water supplier prepare, update, and adopt a Water Shortage Contingency Plan (WSCP) as part of its Urban Water Management Plan pursuant to Water Code sections 10610 through 10657 (UWMP).

The WSCP is a document that provides a water supplier with an action plan for a drought or catastrophic water supply shortage.

A draft 2025 WSCP for the Livermore Municipal Water System has been prepared to meet all the requirements of the Urban Water Management Act (Act ) and has been made available to the public for review and comment prior to a public hearing as required by the Act.

Following the requirements of the Act, a public hearing concerning the 2025 WSCP was publicly noticed, has been held, and public comments about it have been taken.

Adoption of the 2025 WSCP is exempt from the California Environmental Quality Act (CEQA) because California Water Code section 10652 provides that CEQA does not apply to the preparation and adoption of a UWMP, or to projects implementing such plans under Water Code section 10632.

NOW, THEREFORE, B E IT RESOLVED by the City Council of th e City of Livermore, that it hereby:

1. Approves the 2025 Water Shortage Contingency Plan , attached as Exhibit A , and incorporated by this reference.

2. Authorizes transmittal of the 2025 Water Shortage Contingency Plan to the California Department of Water Resources.

3. Authorizes the City Manager to take appropriate and necessary actions to carry out the purpose and intent of this Resolution , including incorporating any necessary amendments as stipulated or directed by the State Department of Water Resources.
