Joint 2025 Urban Water Management Plan
May 2026
On July 3, 2024, the State Water Board adopted specific Making Conservation a California Way of Life regulations. As part of this regulation, Urban Water Suppliers will be held to annual UWUOs. Turlock is required to calculate its UWUO annually, which is a sum of water efficiency budgets for the following uses:
• Residential indoor water use
• Residential outdoor water use
• Real water loss
• CII landscapes with dedicated irrigation meters (DIMs) Turlock’s UWUOs are calculated using statewide efficiency standards, and consider Turlock’s water service area population, climate, and landscape area. Efficiency standards for the different components will become progressively more stringent from 2025 to 2040. Variances and adjustments may be allowed for special cases such as seasonal population fluctuation, special landscape areas (sports fields and recreational areas), potable recycled water use, and agricultural uses. Figure 9-1 summarizes the components that make up the UWUO.
Figure 9-1. Urban Water Use Objective Components5
In addition to calculating and complying with the UWUO, beginning in 2027, Turlock will need to classify its CII properties, and begin deploying BMPs for indoor and outdoor CII water use. These CII performance measures are intended to enable water usage benchmarking per CII classification category, as well as establish BMPs for indoor and outdoor CII water use.
9.4.1 Annual Water Use Reporting
Starting in 2024, Turlock was required to calculate its UWUO, compare its actual water use to its UWUO, and provide an Annual Water Use Report to the State Water Board by January 1 of each year. Reporting is based on fiscal year data. Each year Turlock will need to recalculate its UWUO and meet the applicable UWUO for the year. If it does not meet its UWUO, Turlock will need to develop a plan and intensify existing DMMs or implement new DMMs to improve water use efficiency.

Appendix A
WATER CODE - WAT
DIVISION 6. CONSERVATION, DEVELOPMENT, AND UTILIZATION OF STATE WATER RESOURCES [10000 - 12999] (Heading of Division 6 amended by Stats. 1957, Ch. 1932. ) PART 2.55. SUSTAINABLE WATER USE AND DEMAND REDUCTION [10608 - 10609.42] ( Part 2.55 added by Stats.2009, 7th Ex. Sess., Ch. 4, Sec. 1. )
CHAPTER 1. General Declarations and Policy [10608 - 10608.8] ( Chapter 1 added by Stats. 2009, 7th Ex. Sess., Ch. 4, Sec. 1. )
10608.
The Legislature finds and declares all of the following :
(a) Water is a public resource that the California Constitution protects against waste and unreasonable use. (b) Growing population, climate change, and the need to protect and grow California’s economy while protecting and restoring our fish and wildlife habitats make it essential that the state manage its water resources as efficiently as possible.
(c) Diverse regional water supply portfolios will increase water supply reliability and reduce dependence on the Delta. (d) Reduced water use through conservation provides significant energy and environmental benefits, and can help protect water quality, improve stream flows, and reduce greenhouse gas emissions. (e) The success of state and local water conservation programs to increase efficiency of water use is best determined on the basis of measurable outcomes related to water use or efficiency. (f) Improvements in technology and management practices offer the potential for increasing water efficiency in California over time, providing an essential water management tool to meet the need for water for urban, agricultural, and environmental uses.
(g) The Governor has called for a 20 percent per capita reduction in urban water use statewide by 2020. (h) The factors used to formulate water use efficiency targets can vary significantly from location to location based on factors including weather, patterns of urban and suburban development, and past efforts to enhance water use efficiency.
(i) Per capita water use is a valid measure of a water provider’s efforts to reduce urban water use within its service area. However, per capita water use is less useful for measuring relative water use efficiency between different water providers. Differences in weather, historical patterns of urban and suburban development, and density of housing in a particular location need to be considered when assessing per capita water use as a measure of efficiency. (Added by Stats. 2009, 7th Ex. Sess., Ch. 4, Sec. 1. (SB 7 7x) Effective February 3 , 2010.) 10608.4
It is the intent of the Legislature, by the enactment of this part, to do all of the following :
(a) Require all water suppliers to increase the efficiency of use of this essential resource. (b) Establish a framework to meet the state targets for urban water conservation identified in this part and called for by the Governor.
(c) Measure increased efficiency of urban water use on a per capita basis. (d) Establish a method or methods for urban retail water suppliers to determine targets for achieving increased water use efficiency by the year 2020, in accordance with the Governor’s goal of a 20-percent reduction. (e) Establish consistent water use efficiency planning and implementation standards for urban water suppliers and agricultural water suppliers.
(f) Promote urban water conservation standards that are consistent with the California Urban Water Conservation Council’s adopted best management practices and the requirements for demand management in Section 10631. (g) Establish standards that recognize and provide credit to water suppliers that made substantial capital investments in urban water conservation since the drought of the early 1990s. (h) Recognize and account for the investment of urban retail water suppliers in providing recycled water for beneficial uses.
(i) Require implementation of specified efficient water management practices for agricultural water suppliers. (j) Support the economic productivity of California’s agricultural, commercial, and industrial sectors. (k) Advance regional water resources management.
(Added by Stats. 2009, 7th Ex. Sess., Ch. 4, Sec. 1. (SB 7 7x) Effective February 3, 2010.)
10608.8
(a) (1) Water use efficiency measures adopted and implemented pursuant to this part or Part 2.8 (commencing with Section 10800) are water conservation measures subject to the protections provided under Section 1011. (2) Because an urban agency is not required to meet its urban water use target until 2020 pursuant to subdivision (a) of Section 10608.24, an urban retail water supplier’s failure to meet those targets shall not establish a violation of law for purposes of any state administrative or judicial proceeding prior to January 1, 2021.
Nothing in this paragraph limits the use of data reported to the department or the boa rd in litigation or an administrative proceeding. This paragraph shall become inoperative on January 1, 2021. (3) To the extent feasible, the department and the board shall provide for the use of water conservation reports required under this part to meet the requirements of Section 1011 for water conservation reporting. (b) This part does not limit or otherwise affect the application of Chapter 3.5 (commencing with Section 11340), Chapter 4 (commencing with Section 11370), Chapter 4.5 (commencing with Section 11400), and Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code. (c) This part does not require a reduction in the total water used in the agricultural or urban sectors, because other factors, including, but not limited to, changes in agricultural economics or population growth may have greater effects on water use. This part does not limit the economic productivity of California’s agricultural, commercial, or industrial sectors.
(d) The requirements of this part do not apply to an agricultural water supplier that is a party to the Quantification Settlement Agreement, as defined in subdivision (a) of Section 1 of Chapter 617 of the Statutes of 2002, during the period within which the Quantification Settlement Agreement remains in effect. After the expiration of the Quantification Settlement Agreement, to the extent conservation water projects implemented as part of the Quantification Settlement Agreement remain in effect, the conserved water created as part of those projects shall be credited against the obligations of the agricultural water supplier pursuant to this part. (Added by Stats. 2009, 7th Ex. Sess., Ch. 4, Sec. 1. (SB 7 7x) Effective February 3, 2010.)
DIVISION 6. CONSERVATION, DEVELOPMENT, AND UTILIZATION OF STATE WATER RESOURCES [10000 - 12999] (Heading of Division 6 amended by Stats. 1957, Ch. 1932. ) PART 2.6. URBAN WATER MANAGEMENT PLANNING [10610 - 10657] ( Part 2.6 added by Stats. 1983, Ch. 1009, Sec.. )

10610 This part shall be known and may be cited as the “Urban Water Management Planning Act.” (Added by Stats. 1983, Ch. 1009, Sec. 1.)
10610.2. (a) The Legislature finds and declares all of the following:
(1) The waters of the state are a limited and renewable resource subject to ever-increasing demands. (2) The conservation and efficient use of urban water supplies are of statewide concern; however, the planning for that use and the implementation of those plans can best be accomplished at the local level.
(3) A long-term, reliable supply of water is essential to protect the productivity of California’s businesses and economic climate, and increasing long-term water conservation among Californians, improving water use efficiency within the state’s communities and agricultural production, and strengthening local and regional drought planning are critical to California‘s resilience to drought and climate change.
(4) As part of its long-range planning activities, every urban water supplier should make every effort to ensure the appropriate level of reliability in its water service sufficient to meet the needs of its various categories of customers during normal, dry, and multiple dry water years now and into the foreseeable future, and every urban water supplier should collaborate closely with local land-use authorities to ensure water demand forecasts are consistent with current land-use planning. (5) Public health issues have been raised over a number of contaminants that have been identified in certain local and import ed water supplies. (6) Implementing effective water management strategies, including groundwater storage projects and recycled water projects, may require specific water quality and salinity targets for meeting groundwater basins water quality objectives and promoting beneficial use of recycled water. (7) Water quality regulations are becoming an increasingly important factor in water agencies‘ selection of raw water sources, treatment alternatives, and modifications to existing treatment facilities.
(8) Changes in drinking water quality standards may also impact the usefulness of water supplies and may ultimately impact supply reliability.
(9) The quality of source supplies can have a significant impact on water management strategies and supply reliability.
(b) This part is intended to provide assistance to water agencies in carrying out their long -term resource planning responsibilities to ensure adequate water supplies to meet existing and future demands for water.
(Amended by Stats. 201 B, Ch. 14, Sec. 18. (SB 606) Effective January 1, 201 9.)

(a) Volume of recycled water available for delivery to the North Valley Regional Recycled Water Program (North Valley Program) may vary, as wastewater and recycled water flow projections through 2050 are not available. Volume delivered to the North Valley Program may increase or decrease based on available recycled water supply in future years. (b) Turlock anticipates beginning to deliver recycled water to TID for agricultural irrigation as part of the SRWA-TID Water Sales Agreement water in approximately 2028. (c) The City began its recycled water filling station in 2018. Turlock has not set a limit on the amount of recycled water that can be trucked off-site other than 300 gallons per vehicle per trip. Total fill station use in 2025 was approximately 8,500 gallons, and fill station use is expected to continue to represent only a minor amount of Turlock's overall recycled water use.

NOTES:
(a) Turlock's projected volume of groundwater available is estimated to be the maximum annual groundwater volume pumped in the past five years plus additional capacity from Turlock's future groundwater supply projects identified in DWR Table 6-7R. These future projects include constructing six new wells with treatment by 2040. (b) Turlock's projected volume of purchased water available from SRWA in 2030, 2035, and 2040 assumes a 13.3 MGD allocation for Turlock, based on the WTP's re-rated capacity of 19.9 MGD. Phase 2 expansion of the SRWA WTP from
19.9 MGD to 30 MGD total capacity is assumed to occur in 2041. The Phase 2 expansion yields an allocation of 20 MGD to Turlock in 2045 and 2050; total volume available is limited by Turlock's two-thirds allocation of the maximum annual water supply available per the Water Sales Agreement (9,776 MG). Buildout expansion of the WTP to 45 MGD is not planned within this UWMP planning horizon. (c) Wastewater and recycled water flow projections through 2050 are not available. Volumes presented are based on projected recycled water demands. Actual recycled water supply availability may vary. 2030 2035 2040 2045

NOTES: Reasonably available volume is based on the limiting factor of either 1) WTP capacity or 2) normal-year water allocation between SRWA and TID. Projected volume of surface water available in 2030 through 2040 is based on the WTP's capacity of 19.9 MGD, assuming that the filter re-rating study is completed in 2027. The Phase 2 WTP exansion from 19.9 MGD to 30 MGD total capacity is projected to occur between 2041 and 2045. In 2045 and 2050, reasonably available volume is limited by the normal-year water allocation between SRWA and TID, which is expected to be 98 percent of total volume requested.

Narrative:
SRWA's WTP includes a raw water pump station that extracts raw water from the Tuolumne River via an infiltration gallery. Raw water is then treated, and then pumped via finished water pump stations to the Cities of Turlock and Ceres' terminal reservoirs.
NOTES:
Energy consumption is based on monthly metered electric bills through Turlock Irrigation District (TID) during calendar year 2025. Values are based on energy consumed at SRWA's WTP, including the raw water pump station (shown in the "Extract and Divert" column), treatment system (shown in the "Treatment" column), and finished water pump station (shown in the "Conveyance" column). Volume of water entering process is based on SRWA's total water sales to the Cities of Turlock and Ceres, consistent with DWR Table 4-1 Wholesale.

Supplier's Operational Control
Water Management Process
Energy consumption is based on metered Turlock Irrigation District (TID) billing records for wastewater collection (i.e., sanitary sewer lift stations), treatment facilities, and discharge facilities for Calendar Year 2025. Wastewater volumes are based on metered effluent flow records.
Turlock's wastewater collection/conveyance involves the use of sanitary sewer lift stations, which convey wastewater to Turlock's Regional Water Quality Control Facility (RWQCF). After treatment at the RWQCF, treated effluent is discharged, with most effluent pumped to the Delta-Mendota Canal as part of the North Valley Program, and a smaller amount of effluent used as recycled water within Turlock's water service area.

SUBJECT: Preparation of Joint 2025 Urban Water Management Plan and City of Turlock Water Shortage Contingency Plan
To Whom it May Concern:
This letter is to notify you that the Stanislaus Regional Water Authority (SRWA) and City of Turlock are currently in the process of preparing their Joint 2025 Urban Water Management Plan (UWMP) and the City of Turlock is in the process of updating its Water Shortage Contingency Plan (WSCP).
The Urban Water Management Planning Act, Water Code Section 10610 e t seq., requires every urban water supplier providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre- feet of water annually to prepare and adopt an UWMP and periodically update that plan at least every five years. SRWA’s and the City of Turlock’s Joint UWMP is required to be submitted to the California Department of Water Resources (DWR) by July 1, 2026. The inclusion of a WSCP for each water supplier is a required element of the UWMP per DWR’s UWMP Guidebook 2025.
The UWMP is a planning document and a source document which reports, describes, and evaluates water deliveries and uses, water supply sources , and conservation efforts. The WSCP provides a plan for response to various water supply shortage conditions. As urban water suppliers, SRWA and the City of Turlock are coordinating with water management agencies, relevant public agencies, and other water suppliers on the preparation of the UWMP.
If you wish to contact SRWA and/or the City of Turlock about their review process, you may email [email protected]. Thank you.
Sincerely,
Christopher Fisher

Water Shortage Contingency Plan
1.0 INTRODUCTION
This plan presents the City of Turlock’s (City’s) Water Shortage Contingency Plan (WSCP). The WSCP describes the City’s strategic plan in preparation for and responses to water shortages with a goal to proactively prevent catastrophic service disruptions. It includes water shortage stages and associated actions that will be implemented in the event of a water supply shortage. As part of the WSCP, the City’s legal authorities, communication protocols, compliance and enforcement, and monitoring and reporting are included. The Turlock Municipal Code (TMC) Chapter 6-7 (Water Conservation and Education) provides complementary text that supports the City’s WSCP. This text has been updated over time and is included as Attachment A.
A water shortage may occur due to a number of reasons, such as population growth, climate change, drought, and catastrophic events. Drought, regulatory action constraints, and natural and manmade disasters may occur at any time. A water shortage means that the water supply available is insufficient to meet the normally expected customer water use at a given point in time.
In 2018, the California State Legislature (Legislature) enacted two policy bills, (Senate Bill (SB) 606 (Hertzberg) and Assembly Bill (AB) 1668 (Friedman)) (2018 Water Conservation Legislation), to establish a new foundation for drought planning to adapt t o climate change and the resulting longer and more intense droughts in California. The 2018 Water Conservation Legislation set new requirements for water shortage contingency planning.
The City’s WSCP has been updated so that it is consistent with the 2018 Water Conservation Legislation requirements. The City has modified portions of TMC Chapter 6-7 to support these updates. The City intends for this WSCP to be dynamic, so that it may assess response action effectiveness and adapt to emergencies and catastrophic events. Refinement procedures and adoption requirements are provided in this plan to allow the City to modify this WSCP outside of the Urban Water Management Plan (UWMP) process.
2.0 WATER SUPPLY RELIABILITY ANALYSIS
The City’s water supply reliability analysis and drought risk assessment are included in Chapter 7 of the City’s most recently adopted UWMP. The City’s existing and projected water demands, and existing and planned water supplies are described in Chapter 4 and Chapter 6 of the UWMP, respectively.
The City’s water supplies consist of the following:
• Groundwater pumped from city-owned and operated wells • Treated surface water purchased from Stanislaus Regional Water Authority (SRWA) conveyed from the Tuolumne River through SRWA’s Water Treatment Plant (WTP) • Recycled water from Turlock’s Regional Water Quality Control Facility (RWQCF) During dry periods, SRWA’s surface water allocations from the Turlock Irrigation District (TID) may be reduced. As a result, the City would receive less surface water from SRWA during dry periods and would increase pumping from local groundwater wells to meet remaining demand. While potable supplies will remain reliable and continue to meet water quality standards, the consistency of aesthetic water quality may be affected as water from the City’s groundwater wells is generally less palatable than surface water.

Findings from the water supply reliability analysis show that the City can reliably meet their projected demands through 20 50 in both normal and dry years. For a five -year drought (i.e., the drought risk assessment), no water supply shortfalls are anticipated for the City.
Statewide water supply conditions, changes in groundwater levels, subsidence, and actions by SRWA and TID, may impact the City’s available water supply. For the City, a water shortage condition occurs when the supply of potable water available cannot meet ordinary water demands for human consumption, sanitation, fire protection, and other beneficial uses. The City may be able to foresee its water shortage condition in some cases; however, in other cases, the water shortage may be caused by an unforeseen sudden or emergency event. In general, the City’s water supply conditions may be affected by the following issues:
• Reduction in SRWA surface water allocations from TID during dry years • SRWA WTP operational issues
• City well production and/or groundwater quality issues The City may experience unforeseen water shortage s when catastrophic interruption of water supplies occurs due to regional power outage, an earthquake, or other potential emergency events.
The City conduct s an annual water supply and demand assessment in accordance with Section 3. The analysis associated with this assessment was developed in the context of the City’s water supply sources and reliability.
3.0 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES Beginning July 1, 2022, California Water Code ( CWC) §10632.1 requires water suppliers to submit an Annual Water Supply and Demand Assessment (AWSDA). Water suppliers were also required to submit an Annual Water Shortage Assessment Report beginning July 1, 2022. This WSCP provides the procedures for the City to conduct its AWSDA. The findings from that assessment will provide information for the City’s Annual Water Shortage Assessment Report.
The procedures provided in this section are intended to assist the City in planning for potential , foreseeable shortage in water supplies . These procedures provide the steps the City needs to take that may lead to declaring a water shortage emergency and associated water shortage level (see Section 4) and implementation of water shortage response actions (see Section 5).
3.1 Decision-Making Process
The decision-making process described below will be used by the City to determine its water supply reliability in a consistent manner annually. The City may adjust this process for improved decision-making during implementation.
The Municipal Services Director, or their designee, is responsible for the preparation of the City’s AWSDA and Annual Water Shortage Assessment Report , and submittal of the reports to Department of Water Resources (DWR) by July 1 of each year. The Municipal Services Director, or their designee, will gather key data inputs described in Section 3.2 and conduct the assessment in accordance with Section 3.3. In June, the Municipal Services Director , or their designee , will finalize the assessment based on the SRWA allocated water amount from TID.

Based on the findings of the assessment, the City Council will determine if a water shortage condition exists and, if needed, declare a water shortage emergency and water shortage level and authorize water shortage actions.
The Municipal Services Director , or designee , will then prepare the City’s Annual Water Shortage Assessment Report, incorporating the City Council determinations and approved actions, and submit the report to DWR by July 1.
3.2 Key Data Inputs
The AWSDA requires the evaluation of supply and demands for the current year and one dry year that is assumed to follow the current year. The following key data inputs will be used to evaluate the City's water supply reliability, as necessary and applicable.
Planned water supplies will be used as inputs to the AWSDA for the current year and a subsequent single dry year. The subsequent dry year may be similar to a single dry year as defined in Chapter 7 of the City’s most recently adopted UWMP. In planning for water supplies, the following factors are considered:
1. Hydrologic conditions (e.g., SRWA’s surface water allocations from TID)
2. Regulatory conditions
3. Contractual constraints
4. Surface water and groundwater quality conditions
5. Well production limitations
6. Infrastructure capacity constraints or changes
7. Capital improvement projects implementation
Planned water supply sources and quantities will be described and be reasonably consistent with the supply projections in the City’s most recently updated UWMP Chapter 6 ( Normal-Year Water Supply Characterization) and Chapter 7 (Water Service Reliability and Drought Risk Assessment) . Should the supply sources and projections deviate significantly from projections, an explanation for the difference will be provided.
Planned unconstrained water demands will be used as input to the AWSDA for the c urrent year and a subsequent single dry year. Unconstrained water demands are customer demands where no water conservation measures are in effect. In planning for water demands, the following factors are considered:
1. Weather conditions
2. Water year type
3. Population changes (for example, due to development projects)
4. Anticipated new demands (for example, changes to land use)
5. Pending policy changes that may impact demands
6. Infrastructure operations
Planned water demand types and quantities will be described and be reasonably consistent with the demand projections in the City’s most recently updated UWMP Chapter 4 (Water Use Characterization).

Should the demand projections deviate significantly from projections, an explanation for the difference will be provided.
3.3 Assessment Methodology
In preparing the AWSDA, the City will follow the following assessment methodology and evaluation criteria will be used to evaluate the agency's water supply reliability for the current year and a subsequent single dry year.
The City uses a spreadsheet to plan for current year and future year demands. Planned supply and demand inputs described in Section 3.2 will be entered in the spreadsheet in monthly increments.
Supply and demand will be compared to determine the reliability of the City’s water supply in the current year and a subsequent single dry year. The City’s water supply for the current year and the following dry year will be determined to be reliable if water supply is sufficient to meet the planned water demands.
If water supply is insufficient to meet planned water demands in the current year and/or the following dry year, the extent of the water shortage condition will be determined, and the City will prepare response actions in accordance with this WSCP. As described in Section 3.1.1 and Section 3.1.2, if water supply is insufficient to meet planned wa ter demands, the AWSDA findings will be presented to the City Council, along with recommendations for action for City Council consideration . If water supply is suffi cient, the final approved documents will be submitted to DWR, and no further action will be required.
4.0 STANDARD WATER SHORTAGE LEVELS
To provide a consistent regional and statewide approach to conveying the relative severity of water supply shortage conditions, the 2018 Water Conservation Legislation mandates that water suppliers plan for six standard water shortage levels (or stages) that correspond to progressive ranges of up to 10, 20, 30, 40, 50 percent, and greater than 50 percent shortages from the normal reliability condition. Each shortage condition should correspond to additional actions water suppliers would implement to meet the severity of the impending shortages.
The City’s six water shortage levels align with the State’s standard levels as shown in Table 3 (DWR Table 8-1). The City’s water shortage levels apply to both foreseeable and unforeseeable water supply shortage conditions. Water shortage is the gap between available supply and projected demands.

Table 3. Cross-reference for Standard vs Supplier Shortage Levels (DWR Table 8-1)
As described in Section 3, the City will conduct an AWSDA to determine its water supply condition for the current year and a subsequent single dry year. The preparation of AWSDA helps the City ascertain the need to declare a water shortage emergency and water shortage level. In other cases, the City may need to declare a water shortage emergency due to unforeseen water supply interruptions. When the City anticipates or identifies that water supplies may not be adequate to meet the normal water demand of its customers, the City Council may determine that a water shortage exists and consider a resolution to declare a water shortage emergency and associated level. The shortage level provides direction on which shortage response actions should be implemented.
5.0 SHORTAGE RESPONSE ACTIONS
CWC §10632 (a)(4) requires shortage response actions that align with the defined shortage levels. The City’s shortage response actions include a combination of:
• Demand reduction actions
• Supply augmentation strategies
• Operational changes
The response actions implemented are dependent on the event that precipitates a water shortage level, the time of the year the event occurs, the water supply sources available at that time, and the condition of the City’s water system infrastructure.
The City plans to use a balanced approach that combines demand reduction, supply augmentation, and operational changes to respond to water shortage events. Based on the City’s water supply and demand monitoring described in Section 10, the City will adapt its response actions as necessary to close the gap between water supplies and water demand and to achieve the water use reduction goals associated with the declared water shortage level.
The shortage response actions described below serve as tools that allow the City to respond effectively to water shortage conditions. Because the City is often implementing multiple shortage response actions simultaneously and is continuously adjusting actions as needed to meet water demand reduction goals, it Standard

is difficult to quantify how each action may reduce the supply-demand gap. Therefore, the effectiveness of each shortage response action is provided as an estimate. Certain response actions, such as public outreach and enforcement, support the effectiveness of other response actions but do not directly produce quantifiable water savings on their own.
5.1 Demand Reduction Actions
During water shortage conditions, the City plans to reduce demand by implementing the actions shown in Table 4 and Table 5 (DWR Table 8 -3). Table 4 presents the City’s demand reduction actions organized by the triggering water shortage level . These actions are based on the City’s Water Conservation and Education regulations contained in TMC Chapter 6-7 (Attachment A).
In general , d emand reduction actions are initiated at a specified shortage level and continue to be implemented at higher shortage levels, unless they are replaced by more stringent measures. The City may request that its customers reduce their water use in response to any water shortage level through TMC Chapter 6-7.
Table 5 (DWR Table 8-3) is consistent with Table 4, but also includes additional non-enforcement demand reduction actions, such as public information campaigns and water loss reduction strategies. In addition, Table 5 (DWR Table 8 -3) includes estimates of the potential reduction in the water shortage gap associated with each demand reduction action. For each action, Table 5 (DWR Table 8 -3) also indicates whether the City uses compliance actions such as penalties, charges, or other enforcement.
During the 2012 -2016 drought, the City was able to exceed its water conservation goals using a combination of public outreach and compliance actions. The City found that customers were very responsive to public outreach efforts. A mandatory watering schedule remained in place, although it was not significantly modified in recent years. Conservation efforts focused on continued public education, including promoting the removal of turf grass in landscaped medians, encouraging the use of non-potable water for irrigation where feasible, and maintaining strong messaging through outreach campaigns. The City also distributed home water survey kits and continued rebate programs for high -efficiency appliances. Compared to earlier drought r esponses, the key difference was a shift away from blanket restrictions toward policy-driven conservation triggers tied to local supply conditions, which allowed the City to target actions more effectively.

In addition to demand reduction actions provided in Table 4 and Table 5 (DWR Table 8 -3), the City may impose additional water use restrictions on its customers and enforce the regulations and r estrictions provided in TMC Chapter 6 -7-405 to achieve the percent demand reduction required by the water shortage level.
These additional mandatory restrictions would be implemented alongside any State -mandated prohibitions. The City will enforce both State-mandated prohibitions and its own restrictions.
5.2.1 Water Features and Swimming Pools
Water shortage response would focus on providing sufficient supply to meet health and safety needs for residential customers. Tempering the uses for water features and swimming pools will be based on the severity of the water shortage condition. The relative tot al water use from these sources would be a consideration for how water features would be restricted during specific water shortage conditions.
Water features are a relatively small discretionary use and may be impacted at any time during a triggered water shortage condition.
The City distinguishes special water features, such as decorative fountains and ponds, differently from pools and spas. Special water features are regulated separately. Regulations under TMC 6-7-405 prohibit the use of water in fountains and reflective ponds in Level 3 and more restrictive stages.
5.3 Supply Augmentation and Other Actions
This section discusses the City’s supply augmentation strategies to increase available supply during water shortage conditions. As described in Section 2, t he City’s water supply portfolio includes treated surface water provided from SRWA, local groundwater, and recycled water. The City currently operates 15 active potable groundwater wells and 4 non-potable irrigation wells.
When surface water supplies are reduced, the City relies on its existing potable groundwater wells to meet remaining demands. Based on historical records, the local groundwater basin has proven to be reliable, and drought-related impacts on the City’s grou ndwater supply are not anticipated. As described in the UWMP, the City actively manages its groundwater resources to ensure that water demands can be met even during periods of significantly reduced surface water allocations. In addition, the City has mult iple planned groundwater supply projects intended to maintain existing well capacity.
Table 6 (DWR Table 8 -2) summarizes the City’s potential supply augmentation actions. During water shortage events that result in reduced surface water deliveries, the City may increase pumping from existing production wells and, if necessary, expedite the rehabilitation of existing wells and/or the construction of new production wells to meet demand. Given the City’s planned groundwater capital improvement efforts, the City does not expect to need to augment supplies beyond currently planned projects except under more severe water shortage conditions and/or unforeseen emergency conditions.
Supply augmentation actions related to surface water supply from SRWA are not provided in Table 6 (DWR Table 8-2), as these actions would generally be performed by SRWA and are listed in SRWA’s WSCP. As described in SRWA ’s WSCP, SRWA would notify the City in a timely manner during dry periods when surface water allocations are reduced regarding the timing and magnitude of any surface water supply

reductions. In the event of more severe allocation reductions, SRWA may evaluate opportunities to secure supplemental surface water supplies through alternative water transfer agreements.1 The City does not currently plan to purchase or use water supplies other than local groundwater and surface water provided by SRWA to augment its water supply portfolio.
Table 6. Supply Augmentation and Other Actions (DWR Table 8-2)
5.4 Operational Changes
The City may modify its operations on a short-term or long-term basis in response to any water shortage conditions. The City may take any one or a combination of the following actions.
1. The City may expedite repairs of leaks in its water distribution system. All meter leaks and emergency breaks would be repaired immediately after being reported. Non-emergency service line and main breaks would be repaired within three business days after detection.
2. During the duration of the water shortage condition, the City may limit its regular maintenance water system flushing operations such that flushing is conducted only in areas with known water quality issues.
5.5 Emergency Response Plan
As stated in Section 4, the City’s water shortage levels outlined in TMC Section 6-7-405 apply to both foreseeable and unforeseeable water supply shortage conditions, including catastrophic water shortage conditions.
The City’s 2023 Water Distribution System Operations Plan includes an Emergency Response Plan (ERP) that addresses extreme weather emergencies such as droughts when catastrophic water shortage conditions may occur. Water shortage emergency response is coordinated with the County’s Office of Emergency Services. The ERP outlines response procedures associated with unforeseeable incidents such as water supply contamination, earthquake, infrastructure failure, and other events . The ERP includes

actions to be taken in preparation for, during, and recovery from such events. To maintain the security of the City’s water system, the ERP is retained as a confidential document.
The City’s response planning for continued water service includes the use of standby generators, water purification supplies and equipment, emergency drinking water storage, and water trucks. Water storage, treatment, and pumping facilities have been const ructed to meet earthquake safety standards and are inspected regularly.
The City has access to surface water from the Tuolumne River through the SRWA WTP. This facility may supply emergency water to maintain normal distribution if the City’s groundwater supply is impacted by a catastrophic supply interruption. Alternatively, if the catastrophic interruption is related to the surface water supply, the City will use the existing groundwater wells to provide sufficient water for health, sanitation, and fire protection for the duration of the emergency. If there is a catastrophic s upply interruption that impacts both the City’s groundwater supply and the surface water supply from SRWA, then outside emergency water supply assistance would be needed.
6.0 COMMUNICATION PROTOCOLS
In the event of a water shortage, the City must inform its customers, the general public and interested parties, and local, regional, and state entities. Communication protocols for foreseeable and unforeseeable events are provided in this section. In any event, timely and effective communication must occur for ap propriate response to the event. C ity staff are provided with cell phones and City email accounts to communicate internally and externally.
6.1 Communication for Foreseeable Events
Water shortages may be foreseeable when the City conducts its AWSDA as described in Section 3. When the City determines the potential for a water shortage event, the City Council may find, determine and declare a water shortage emergency , and the associated water shortage level, in accordance with TMC Chapter 6-7-403.
The following communications protocol and procedures will be followed. The City may trigger any of these communication protocols at any water shortage level.
1. If a water shortage emergency is anticipated, the City will coordinate interdepartmentally and with Stanislaus County for the possible proclamation of a local emergency.
2. The City may hold a duly noticed City Council meeting in which the AWSDA findings and recommendations for a water shortage emergency and shortage response actions are presented.
3. The Municipal Services Director, or his or her designee, shall monitor the projected supply and demand for water by its customers, with heightened emphasis during the months of March through October.
4. The Municipal Services Director, or his or her designee, shall recommend to the City Manager and City Council the extent of the conservation compliance stage required in order for the City to prudently plan for and supply water to its customers.
5. The City Council may order that the appropriate stage of water conservation be implemented or terminated in accordance with the applicable provisions of this chapter.
Water Shortage Contingency Plan
N-C-693-20-16-01-WP-TASK 20
14 City of Turlock
Water Shortage Contingency Plan
Last Revised: May 2026
When implementing mandatory water conservation compliance Stages 2, 3, 4, 5 and 6, said order shall be made by public announcement and shall be published a minimum of one (1) time in a daily newspaper of general circulation and shall become effective immediately upon such publication. Other forms of communication to inform customers, the public, and government entities shall include social media postings, email to customers and businesses in Turlock and radio broadcast. Public entities and officials are informed of water shortage information via email.
6.2 Communication for Unforeseeable Events
Water shortage s may occur during unforeseeable events such as earthquakes, fires, infrastructure failures, civil unrest, and other catastrophic events. The C ity’s 2023 Water Distribution System Operations Plan includes an Emergency Notification Plan (ENP) and ERP that provide specific communication protocols and procedures to convey water shortage contingency planning actions during these events. The City may trigger any of these communication protocols at any water shortage level, depending on the event.
The ENP provides a list of relevant contacts to notify in the event of an emergency at the local, regional, and state level. The ERP lists the City’s emergency plans and procedures, resilience strategies, and mitigation actions. To maintain the security of the C ity water system , the Water Distribution System Operations Plan is maintained as a confidential document and may not be incorporated in this UWMP.
In general, communications and notifications should proceed along the chain of command. Notification decisions will be made under the direction of the Municipal Services Director or their designee. External communications will be managed by the Municipal Services Director or their designee. All City staff are provided their communication responsibilities. The Regulatory Compliance Officer and the Municipal Services Director will work with the Municipal Services Department staff to notify regulatory agencies.
7.0 COMPLIANCE AND ENFORCEMENT
TMC Chapter 6-7 supports the implementation of the City’s WSCP actions. This text includes provisions for compliance and enforcement of its water use regulations, restrictions, and prohibitions and is available on the City’s website. The City’s water conservation website (https://www.cityofturlock.org/watersewergarbageservice/waterconservation/ ) provides the most current regulations and water restrictions.
When a water shortage is anticipated, the City Council determines the degree of the water shortage emergency and makes a declaration of the water shortage stage. The City Council may also hold a duly noticed public meeting to discuss the water shortage emergency.
Since the City’s water service area is fully metered, customer water use can be quantified and compared to determine their extent of compliance to water reduction requirements. The City may also become aware of non -compliance through its water waste reporting outreach or throug h staff inspections.
Non-compliance is deemed as a violation and is classified as an infraction. Each day of continued violation is considered as a separate offense.
The Municipal Services Director or their designee and duly designated representatives are authorized to enforce provisions of TMC Chapter 6 -7 and make determinations with regard to the customer water

N-C-693-20-16-01-WP-TASK 20
15 City of Turlock
Water Shortage Contingency Plan
Last Revised: May 2026
allocations provided in TMC Chapter 6-7. For these purposes, they have the power and discretion of a law enforcement office.
7.1 Shortage Level Enforcement and Penalties
Enforcement and penalties for non-compliance with restrictions associated with a water shortage level or stage are provided in TMC 6-7-410. When the City becomes aware of a customer violating, causing, or permitting a violation of the restrictions or prohibitions associated with the adopted water shortage level, the City will issue a notice that describes the nature of the violation and includes an order that the violation be corrected within a stated period. Upon occurrence of a second violation or failure to correct the initial violation, the City will issue a second notice ordering immediate correction and imposing a surcharge as provided in the TMC . Upon occurrence of a third violation or failure to correct the initial violation, the City will issue a third notice ordering immediate correction and imposing a surcharge as provided in the TMC. Upon occurrence of a fourth violation, and each subsequent violation, or failure to correct the initial violation, the City will issue an additional notice ordering immediate correct ion and imposing a surcharge as provided in the TMC. The Municipal Services Director, or designee, may issue an order to cease and desist until appropriate remedial actions are taken. For continued violation, the Municipal Services Director or designee may order discontinuance of service.
The thirty days after the effective date of the Council’s declaration of a water shortage emergency or the effective date stated in the resolution is considered as an adjustment period . During that period, no penalties will be imposed on violations to water use prohibitions and restrictions associated with the water shortage emergency.
After the initial thirty days after the effective date, customers are subject to enforcement and penalties associated with water use prohibitions and restrictions . For continued violation, the City may impose progressively stringent action, from issuance of a warning to increasing penalties and fines.
7.2 Appeal and Exemption Process
Per TMC Chapter 6-7-411 and 6-7-412, utility customers may appeal a Notice of Acts Constituting Water Wasting by submitting a written appeal to the Municipal Services Director within fifteen calendar days from the date of service of the Notice of Acts Constituting Water Wasting, or any water wasting penalty assessed to his or her account . The written appeal should include supporting facts and reasons. The hearing officer may hold an appeal hearing, where the appellant and the Municipal Services Director are heard. At the conclusion of hearing the appeal, the hearing officer may affirm, reverse or modify the Notice of Acts Constituting Water Wasting. The hearing officer’s action on the appeal is final.
8.0 LEGAL AUTHORITIES
Title 6, Chapter 7, Article 4 of the TMC includes provisions for the emergency water shortage plan. When a water shortage is determined, the City will coordinate interdepartmentally , with SRWA, and with Stanislaus County for the possible proclamation of a local emergency in accordance with California Government Code, California Emergency Services Act (Article 2, § 8558).
In accordance with TMC Chapter 6-7 and California Water Code Chapter 3, Division 1, § 350 et seq, the City Council is required, unless an immediate emergency exists, to conduct a duly noticed public meeting for the purpose of determining whether a water shortage emergency condition exists and, if so, the
Water Shortage Contingency Plan
N-C-693-20-16-01-WP-TASK 20
16 City of Turlock

Last Revised: May 2026
degree of the emergency and what regulations and restrictions should be enforced in response to the shortage. The City shall declare a water shortage emergency in accordance with CWC Chapter 3 Division 1.
Water Code Section Division 1, Section 350
…The governing body of a distributor of a public water supply…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.
The water shortage emergency declaration triggers communication protocols described in Section 6 of this WSCP and compliance and enforcement actions described in Section 7 of this WSCP.
9.0 FINANCIAL CONSEQUENCES OF WSCP
The City maintains an adequate operational reserve to protect against a temporary water shortage. The City anticipates reduced revenue due to decreased water use by its customers and additional costs associated with implementing water use restrictions and associated compliance actions. Reduced revenue and costs associated with compliance actions are considered in the City’s water rate study.
10.0 MONITORING AND REPORTING
The City’s water system is fully metered, from production facilities to individual customer connections, allowing for comprehensive monitoring of system supplies and demands. Water production data may be read on a daily basis. These meters may be used as monitoring tools for compliance and reporting purposes. The City regularly records its water meter readings, along with enforcement actions, to comply with State reporting requirements.
Meters can be read as frequently as needed to track the effectiveness of implemented response actions.
Water production and water use can be compared to historical periods, analyzed by customer sector or at the individual customer level. This continuous monitoring allows the City to assess water system demands and compare it with its water demand reduction goals.
Based on these assessments, t he City may adjust its shortage response actions to better align with its water demand reduction goals. For example, the City may intensify its public outreach or more rigorously enforce compliance with water use prohibitions if water demand reduction goals are not met for a specific shortage level.
11.0 WSCP REFINEMENT PROCEDURES
This WSCP is an adaptive management plan. It is subject to refinements as needed to ensure that the City’s shortage response actions and mitigation strategies are effective and produce the desired results. Based on monitoring described in Section 10 and the need for compliance and enforcement actions described in Section 7 of this WSCP/ TMC 6-7-410, the City may adjust its response actions and may modify its WSCP.
When a revised WSCP is proposed, the revised WSCP will undergo the process described in Section 12 for adoption by the City Council and distribution to the City, its customers, and the general public.
Feedback from City staff and the public is important in refining or incorporating new actions. The City seeks input from staff who interface with customers to gauge the effectiveness of its response actions
Water Shortage Contingency Plan
N-C-693-20-16-01-WP-TASK 20
17 City of Turlock
Water Shortage Contingency Plan
Last Revised: May 2026
and for response action ideas. The City seeks input from its customers and the general public through its website, through public hearings, and through regularly scheduled City Council meetings.
Customer water meter data may be evaluated for each customer sector or each individual customer. The City tracks water use violations and may evaluate their frequency to determine restrictions that customers may not be able to meet. This evaluation may also show water demand reduction actions that customers may effectively implement.
12.0 PLAN ADOPTION, SUBMITTAL, AND AVAILABILITY
This WSCP is adopted concurrently with the City’s Joint 2025 UWMP, by separate resolution. Prior to adoption, a duly noticed public hearing was conducted. An electronic copy of this WSCP will be submitted to the DWR within 30 days of adoption.
No later than 30 days after submittal to DWR, this WSCP will be available at the City’s offices. A copy will also be provided to Stanislaus County. An electronic copy of this WSCP as well as the Joint 2025 UWMP will also be available for public review and download on the City’s website.

Water Shortage Contingency Plan
A water shortage may occur due to a number of reasons, such as population growth, climate change, drought, and catastrophic events. Drought, regulatory action constraints, and natural and manmade disasters may occur at any time. A water shortage means that the water supply available is insufficient to meet the normally expected customer water use at a given point in time.
This plan presents the Stanislaus Regional Water Authority (SRWA)’s Water Shortage Contingency Plan (WSCP). The WSCP describes SRWA’s strategic plan in preparation for and responses to water shortages with a goal to proactively prevent catastrophic service disruptions. It includes water shortage levels and associated actions that will be implemented in the event of a water supply shortage. As part of the WSCP, SRWA’s legal authorities, communication protocols, compliance and enforcement, and monitoring and reporting are included.
In 2018, the California State Legislature enacted two policy bills, (Senate Bill 606 (Hertzberg) and Assembly Bill 1668 (Friedman)) (2018 Water Conservation Legislation), which set new requirements for water shortage contingency planning.
SRWA’s WSCP has been prepared consistent with the 2018 Water Conservation Legislation requirements.
Refinement procedures and adoption requirements are provided in this plan to allow SRWA to modify this WSCP outside of the Urban Water Management Plan (UWMP) process.
1.0 WATER SUPPLY RELIABILITY ANALYSIS
Chapters 6 and 7 of SRWA’s 2020 UWMP present SRWA’s water supply sources and reliability, respectively. Findings show that SRWA’s five consecutive dry year supplies, single-dry year supplies, and even normal year supplies, whether occurring now or 20 years in the future, may be insufficient to meet projected demands – meaning that SRWA’s wholesale customers, the City of Ceres (Ceres) and City of Turlock (Turlock) (Cities), cannot rely entirely on SRWA’s surface water supplies to meet their demands.
Statewide water supply conditions, hydrologic conditions, changes in groundwater levels, subsidence, and actions by other agencies, may impact SRWA’s available water supply. For SRWA, a water shortage condition occurs when the supply of potable water available cannot meet its customers’ normal water demands for human consumption, sanitation, fire protection, and other beneficial uses.
The analysis associated with this WSCP was developed in the context of SRWA’s water supply sources and system reliability. In some cases, SRWA may be able to foresee its water shortage condition, but the water shortage may also be caused by an unforeseen emergency event. In general, SRWA’s water supply conditions may be affected by the following:
• Turlock Irrigation District (TID) supply allocations and storage levels, and resulting allocation reductions to TID customers, and
• Timing and frequency of TID’s curtailment periods, and changes in Tuolumne River water quality that could not be addressed by the Regional Water Treatment Plant (WTP).
SRWA may also experience unforeseen water shortages when catastrophic interruption of water supplies occurs due to regional power outages, earthquakes, or other potential emergency events. In response to supply shortfalls, SRWA may declare a water shortage level (as described in Section 4.0).
In future years, SRWA will conduct an annual water supply and demand assessment in accordance with Section 2. The analysis associated with this WSCP was developed in the context of SRWA’s water supply sources and reliability.

Adopted: 10-17-24
2.0 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES Beginning July 1, 2022, California Water Code (CWC) §10632.1 requires water suppliers to submit an Annual Water Supply and Demand Assessment (AWSDA). Water suppliers are also required to submit an Annual Water Shortage Assessment Report beginning July 1, 2022. This WSCP provides the procedures for SRWA to co nduct its AWSDA. The findings from that assessment will provide information for SRWA’s Annual Water Shortage Assessment Report.
Since SRWA did not begin operations until November 2023, and will not complete its first UWMP until November 2024, SRWA’s first AWSDA will be submitted to the California Department of Water Resources (DWR) by July 1, 2025.
The procedures provided in this section are intended to assist SRWA in planning for potential, foreseeable shortage in water supplies. These procedures provide the steps SRWA needs to take that may lead to declaring a water shortage emergency and associate d water shortage level (see Section 3) and implementation of water shortage response actions (see Section 4).
2.1 Decision-Making Process
The decision -making process described below will be used by SRWA to determine its water supply reliability in a consistent manner annually. SRWA may adjust this process for improved decision -making during implementation.
SRWA staff will prepare the Annual Water Shortage Assessment Report and submit it to DWR by July 1 of each year. Key data inputs described in Section 2.2 will be gathered and the assessment will be conducted in accordance with Section 2.3.
Staff will follow the sequence of activities shown in Table 1. Due to variations in climate and hydrologic conditions, SRWA’s assessment schedule may vary. SRWA intends to implement shortage response actions to effectively address anticipated water shortage conditions in a timely manner while complying with the State’s reporting requirements. SRWA recognizes that its wholesale customers’ AWSDA reporting and timely response to water shortage events is directly affected by its AWSDA. SRWA must complete its assessment in order to allow the Cities to complete their AWSDA reporting.
Typically, by the end of March of each year, SRWA will complete the assessment. Staff will present the AWSDA and Annual Water Shortage Assessment Report to the General Manager, or designee, for review and approval. If the AWSDA finds that available water supply will be sufficient to meet expected demands for the current year and one subsequent dry year, no further action will be required. The final approved documents will be submitted to DWR by July 1st of each year.

Before July 1 Submit the AWSDA and Annual Water Shortage Assessment Report to DWR.
Should the annual assessment find that available supply will not meet expected demands, SRWA will coordinate with its customers to inform them of the AWSDA results. SRWA will inform the Cities that they will need to implement their WSCP and utilize alternative sources (i.e., City groundwater resources) to close the anticipated water supply gaps. The General Manager will present the finalized assessment to the Board, along with recommendations on water shortage condition determination and actions.
Recommended actions may include declaration of a water shortage emergency, declaration of a water shortage level, and water shortage actions.
Based on the findings of the Annual Assessment, the Board will determine if a water shortage condition exists and, if needed, adopt a resolution declaring a water shortage emergency and an associated water shortage level, and authorizing water shortage actions. Staff will finalize the SRWA’s Annual Water Shortage Assessment Report, incorporating Board determinations and approved actions.
The schedule of decision-making activities is provided in Table 2. The schedule and the activities shown in this table are approximate and may be adjusted as needed to respond to the water shortage condition in a timely manner.

2.2 Key Data Inputs
The AWSDA requires the evaluation of supply and demands for the current year and one dry year that is assumed to follow the current year. The following key data inputs will be used to evaluate SRWA's water supply reliability.
Planned water supplies will be used as input to the AWSDA for the current year and the following one dry year. In planning for water supplies, the following factors are considered:
Delivery requests from the Cities, typically received by December 1 the year prior Schedule of delivery, typically received from TID by mid-March Hydrologic conditions
Regulatory conditions
Contractual constraints
Surface water and groundwater quality conditions
Well production limitations
Infrastructure capacity constraints or changes
Capital improvement projects implementation
Planned water supply sources and quantities will be described and be reasonably consistent with the supply projections in SRWA’s last updated UWMP Chapter 6 (Water Supply Characterization). Should the supply sources and projections deviate significantly from projections, an explanation for the difference will be provided in the AWSDA report.
Planned unconstrained water demands will be used as input to the AWSDA for the current year and the following assumed dry year. Unconstrained water demands are customer demands where no water conservation measures are in effect. In planning for water demands, the following factors are considered:
Weather conditions
Water year type
Population changes (for example, due to development projects) Anticipated new demands (for example, changes to land use) Pending policy changes that may impact demands
Infrastructure operations
Planned water demands types and quantities will be described and be reasonably consistent with the demand projections in SRWA’s last updated UWMP Chapter 4 (Water Demand Characterization).
Should the demand projections deviate significantly from projections, an explanation for the difference will be provided in the AWSDA report.

In preparing the AWSDA, SRWA will follow the following assessment methodology and evaluation criteria to evaluate SRWA’s water supply reliability for the current year and a n assumed subsequent dry year.
SRWA will assess the data listed in Section 2.2 to develop its supply and demand forecasts, which are then compared to determine SRWA’s water supply reliability. SRWA’s water supply will be deemed reliable if it can meet planned, unconstrained water demands. If water supply cannot meet planned, unconstrained water demands in the current year or the following assumed dry year, the extent of the water shortage

condition will be determined. SRWA will prepare recommended response actions in accordance with this WSCP. Findings from the AWSDA will be presented to the SRWA Board, along with the recommendations for action.
3.0 SIX STANDARD WATER SHORTAGE LEVELS
To provide a consistent regional and statewide approach to conveying the relative severity of water supply shortage conditions, the 2018 Water Conservation Legislation mandated that water suppliers plan for six standard water shortage levels that correspond to progressive ranges of up to 10, 20, 30, 40, 50 percent, and greater than 50 percent shortages from the normal reliability condition. Each shortage condition should correspond to additional actions water suppliers would implement to meet the severity o f the impending shortages.
For each of the State’s standard shortage levels, Table 3 (DWR Table 8-1), summarizes the water shortage range (i.e., percent shortage from normal supplies), a brief narrative description of the corresponding water shortage condition, and the corresponding shortage response actions. These water shortage levels apply to both foreseeable and unforeseeable water supply shortage conditions.
As described in Section 2, beginning in 2025, SRWA will conduct an AWSDA to determine its water supply condition for the current year and a subsequent assumed dry year. The preparation of AWSDA will help SRWA ascertain the need to declare a water shortage emergency and water shortage level. In other cases, SRWA may need to declare a water shortage emergency due to unforeseen water supply interruptions.
When SRWA anticipates or identifies that water supplies may not be adequate to meet the normal water supply needs of its customers, the SRWA Board will inform its customers that they will need to implement their WSCP and rely on alternative sources (i.e., City groundwater resources) to close the anticipated gap between supply and demand . The SRWA Board may also determine that a water shortage exists and consider a resolution to declare a water shortage emergency and associated level. The shortage level provides direction on shortage response actions.

4.0 SHORTAGE RESPONSE ACTIONS AND EFFECTIVENESS
CWC Section 10632 (a)(4) requires shortage response actions that align with the defined shortage levels.
SRWA’s shortage response actions consist of a combination of demand reduction, supply augmentation, and operational changes. SRWA’s suite of response actions are dependent on the event that precipitates a water shortage level, the time of year the event occurs, the water supply sources available, and the condition of its water system infrastructure.
SRWA plans to use a balanced approach, combining supply augmentation, and operational changes to respond to the event and the resulting water shortage level. SRWA will adapt its implementation of response actions to close the gap between water supplies and water demand and meet the water use goals associated with the declared water shortage level.
SRWA’s water system is fully metered, from production to Cities’ turnouts. Records of water deliveries to each wholesale customer is prepared daily and can be used to track the effectiveness of SRWA’s response actions. Water production and water use can be compared to the previous year, previous month, or previous week. Water use can also be compared by wholesale customer. This continuous monitoring allows SRWA to evaluate its demand reduction efforts in real-time and adjust its shortage response actions accordingly.
As noted above, SRWA’s overall shortage response will be dynamic to close the gap between water supply and demands to meet the goal of the declared shortage level. For example, SRWA may intensify its public outreach or work with the Cities to enforce water use prohibitions more vigorously if water demand reduction goals are not met.
The shortage response actions discussed below may be considered as tools that allow SRWA to respond to water shortage conditions. Because SRWA may continuously monitor and adjust its response actions to reasonably equate demands with available supply, the extent to which implementation of each action reduces the gap between water supplies and water demand is difficult to quantify and thus only estimated. Certain response actions, such as working with the Cities to adjust surface water delivery schedules, support the effectiveness of other response actions and do not have a quantifiable effect on their own.
4.1 Demand Reduction
Since SRWA operates as a wholesale water agency, it cannot set or enforce consumption limits at the customer (e.g., household) level. As a result, this WSCP does not include per capita allotment, penalties, or customer incentives for conservation for any customer sector. SRWA may request that their wholesale customers reduce demands when supplies are insufficient. SRWA’s wholesale customers will implement their respective WSCP, including any demand reduction response.
For all the shortage levels identified in Table 3 (DWR Table 8-1), SRWA is responsible for informing the Cities in a timely manner of the timing and extent of water supply reductions . SRWA will work with the Cities to schedule deliveries of limited surface water supplies.
Table 4 (DWR Table 8-2) summarizes SRWA’s demand reduction actions, or perhaps more appropriately supply management actions, at different levels of supply reductions. SRWA will share water production metered data with the Cities so that they may ascertain the effectiveness of their demand reduction actions.

4.2 Additional Mandatory Restrictions
As a wholesaler, SRWA does not have direct authority to institute water use prohibitions. SRWA will support mandatory restrictions imposed by the Cities on their customers and coordinate with the Cities to provide consistent public outreach messaging. SRWA will share water production metered data with the Cities so that they may ascertain the effectiveness of their mandatory restrictions.
4.3 Supply Augmentation and Other Actions
Chapter 6 of SRWA’s 2020 UWMP describes SRWA’s normal water supply portfolio, as well as dry -year and emergency supplies. SRWA uses entirely surface water supplies from the Tuolumne River. In the event of a dry year or other water supply interruption, when SRWA’s water allocations from TID are insufficient to meet all SRWA’s wholesale customer demands, SRWA will consider the option of purchasing additional water supplies from other TID customers or other upstream water right holders for diversion from the Tuolumne River via SRWA’s intake.
4.4 Operational Changes
SRWA may modify its operations on a short -term or long-term basis in response to any water shortage condition. SRWA may take any one or a combination of the following actions:
Reduce pumping according to the reduction in water allocation from TID that may come with the various levels of water shortage.
Investigate supplemental surface water purchase options.
Coordinate with the Cities to adjust the WTP capacity allocation for a limited period of time to augment one city’s supply, while reducing the other city’s supply. The capacity of the Cities’ Treated Water Transmission Pipelines is designed for buildout of each city. The Cities have flexibility for the season or months that the City receives a reduced allocation, as the Cities can use groundwater from their wells to meet their customer water demands throughout the year.
While SRWA will employ whatever operational changes may be necessary to respond to water shortage conditions, it will also prioritize maintaining a minimum diversion of 5 million gallons per day (MGD) each day to keep the WTP operational. When maintaining the minimum 5 MGD flow appears unlikely, SRWA will more seriously consider a supplemental surface water purchase to avoid the need to shut down the WTP.

4.5 Emergency Response Plan
As stated in Section 3, SRWA’s water shortage levels apply to both foreseeable and unforeseeable water supply shortage conditions.
SRWA is currently preparing its Emergency Response Plan (ERP) to support final operational permitting.
The ERP is anticipated to be completed in October 2024. In addition, the ERP is being prepared to meet the requirements of the America’s Water Infrastructure Act of 2018 (AWIA). AWIA requires community water systems serving greater than 3,300 people to prepare or revise an ERP on a 5-year cycle. Since SRWA began operation in November 2023, the AWIA ERP compliance date of September 30, 2025 will be its first.
Prior to this compliance date, SRWA will self -certify with the United States Environmental Protection Agency that the ERP has been updated.
The ERP outlines all -hazards response procedures for incidents such as water supply disruption, water supply contamination, earthquake, infrastructure failure, and other events. The ERP includes actions to be taken in preparation for, during response operations, and in recovery from such events. It also includes guidance and procedures for engaging with response partners such as Stanislaus County for water shortage emergencies.
SRWA’s current capabilities to prevent and respond to potential water service disruptions includes use of standby generators, storage of several weeks’ worth of treatment chemicals, and capable operations staff. Water storage, treatment, and pumping facilities have been constructed to meet earthquake safety standards.
5.0 COMMUNICATION PROTOCOLS
In the event of a water shortage, SRWA must inform their customers, the general public and interested parties, and local, regional, and state entities. Communication protocols for foreseeable and unforeseeable events are provided in this section. In any event, timely and effective communication must occur for appropriate response to the event.
5.1 Communication for Foreseeable Events
Water shortage may be foreseeable when SRWA conducts its AWSDA as described in Section 2. For foreseeable water shortages, SRWA will follow the communication protocols and procedures detailed below. SRWA may trigger any of these protocols at any water shortage level.
If a water shortage emergency is anticipated, SRWA will coordinate with Stanislaus County and SRWA’s wholesale customers for the possible proclamation of a local emergency.
SRWA will schedule a duly noticed Board meeting in which the AWSDA findings and recommendations for a water shortage emergency and shortage response actions are presented.
SRWA will communicate conditions to the general public using some or all of the following options, as needed at the various shortage levels: press releases, radio/television coverage, social media posts, and postings on SRWA’s website. Public entities and officials are informed of water shortage information via email.
