3.4.4 Per- and Polyfluoroalkyl Substances (PFAS)
The USEPA released lifetime HA levels for several PFAS compounds in 2022 while the agency simultaneously worked on establishing a federal drinking water regulation. Table 4 lists the federal HAs.

California SWRCB has established NLs and RLs for four PFAS, which are also listed in Table 4. Zone 7 and the City (Wells 5, 6, and 8) are included in the latest order from DDW requiring monitoring for PFAS.

Zone 7 has some groundwater wells that have tested above the response level for PFOS and PFHxS. For Mocho wells, Zone 7 is treating at its Mocho Groundwater Demineralization Facility and/or blending so that delivered drinking water is below Response Levels. Stoneridge well and and Chain-of-Lake wells have been taken offline and are currently under construction for added PFAS treatment. All other wells and surface water treatment plants have not detected PFAS.

For the City, Well 8 has tested above the response level for PFOS and PFHxS and as a result has been put in Standby Service with DDW and has not operated since 2019.

September 2022, the City Council authorized a Water Supply Alternatives Study to evaluate water supply alternatives for the portion of water supply currently sourced by the City’s local groundwater wells. These alternatives include continuing to utilize the City’s local groundwater (by adding PFAS treatment or constructing new wells) or purchasing water in lieu of local groundwater pumping. These alternatives will be evaluated against multiple criteria including cost, water supply reliability, regulatory compliance, operational complexity, administration, and implementation feasibility to determine the preferred alternative. The results of this effort are scheduled to be available at the end of 2023.

CITY OF PLEASANTON
WATER SYSTEM MANAGEMENT PLAN 10
On March 14, 2023, the USEPA released its proposed regulation for PFAS in drinking water. The draft NPDWR proposes a MCL of 4 ng/L for PFOA and PFOS. Four additional PFAS (GenX, PFBS, PFNA, and PFHxS) are also included under the draft regulation. The EPA proposes the use of a Hazard Index, a tool to evaluate public health risks based on exposure to chemical mixtures. Although hazard indices have been used in other government programs, like the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the EPA has not previously used this on drinking water standards. The Hazard Index for the PFAS mixture is 1.0 (unitless Hazard Index). MCLGs for each PFAS are 0 ppt for PFOA and PFOS and 1 (unitless Hazard Index) for the PFAS mixture.

The proposed regulation will undergo a public comment period for the next 60 days. Then, the USEPA will review the provided feedback and finalize the regulation. The City will be required to provide PFAS treatment for Well 5, 6, and 8 to keep wells operational under the proposed regulations.

3.4.5 Consumer Confidence Reports
On March 28, 2023, the USEPA released a proposed rulemaking to strengthen the CCR. The draft rulemaking would change several aspects of the CCR including more electronic delivery options and increased risk communication. Most notably, the CCR would require reports to be issued twice a year, instead of annually, and states will be required to submit compliance monitoring data to the USEPA (USEPA, 2023).

The proposed regulation will undergo a public comment period for the next 60 days. Then, the USEPA will review the provided feedback and finalize the regulation. The City will need to comply with the finalized CCR rulemaking once it has been established.

SECTION 4 POTENTIAL FUTURE REGULATIONS
The 1986 Amendments to the SDWA established requirements for the USEPA to publish a list of chemical and microbial contaminants (the Contaminant Candidate List, CCL) every five years to review for potential regulation. Every five years, the USEPA is required to identify five of the contaminants from that list for regulation determination. The regulatory determination could either be a decision to regulate, or decision not to regulate, in which case the contaminant is removed from future CCLs. The Unregulated Contaminant Monitoring Rule (UCMR), also set forth in the 1986 SDWA Amendments, requires that the USEPA publish a list every five years of contaminants designated for occurrence monitoring to support assessment of whether regulation would provide meaningful health risk reduction. Figure 3 illustrates the CCL and UCMR process.

The third principal component of the 1986 SDWA Amendments establishing the process for USEPA to continually assess the need for drinking water regulations to protect public health is the Six Year Review process. The US EPA is required to review existing NPDWRs every six years to evaluate the efficacy of rule revisions based on new information on occurrence or public health risks.

Figure 3 USEPA Process for Establishing New Drinking Water Regulations (AWWA, 2015) Table 5 summarizes the contaminants included in each CCL and resulting regulatory determinations. To date, five CCLs have been reviewed and prepared. USEPA began the process of developing CCL 6 in February 2023 by requesting nomination of chemicals, microbes, or other materials for consideration. As a result of the first four CCL processes, the USEPA has determined not to regulate 29 different chemical contaminants and 1 microbial contaminant. The USEPA made a decision to regulate perchlorate 1 as an outcome of CCL2, strontium as an outcome of CCL3, and PFOS and PFOA as an outcome of CCL4.

Microplastics SWRCB released guidance on testing

4.1 Microbial / Disinfection Byproducts (M/DBP) Rule
The EPA identified eight contaminants covered by the M/DBPRs as candidates for regulatory revision as part of the six-year review process. The eight candidates are: Chlorate, Cryptosporidium, HAA5, heterotrophic bacteria, Giardia lamblia, Legionella, TTHMs, and viruses. These contaminants are including in several M/DBP rules:
 Stage 1 and Stage 2 D/DBPR
 Surface Water Treatment Rule
 Interim Enhanced Surface Water Treatment Rule (IESWTR)  Long Term 1 Enhanced Surface Water Treatment Rule (LT1) The National Drinking Water Advisory Council (NDWAC), a federal advisory committee that provides the EPA with advice and recommendations related to drinking water, created a working group to discuss and collect public feedback on the MDBP revisions (USEPA, 2023). As of March 2023, the working group has met seven times since May 2022 to discuss how to improve the existing regulations. In addition, the EPA is conducting analyses to further evaluate the eight contaminants. Unregulated DBPs, like chlorate and nitrosamines, are also being evaluated in this effort (USEPA, 2023).

The USEPA’s decision on the M-DBP rule may adjust how the City treats contaminants captured under the rule. Potential revisions could include, but are not limited to:
 A numeric value for the minimum disinfectant residual  Revised MCLs for HAAs to encompass brominated species (e.g., an MCL for HAA9 or HAA6Br)  Chlorate MCL
 Legionella monitoring
Nitrification can result in a disinfectant residual loss. The City’s Nitrification Evaluation (Carollo, 2019) provided recommendations to monitor parameters for early warning of a nitrification event and identified potential control measures. Nitrification control will be an important aspect of complying with any revised numeric disinfectant residual level.

Based on a review of the City’s UCMR4 data, maximum HAA6Br and HAA9 concentrations are low (22 and 29 µg/L, respectively). Despite elevated bromate concentrations in some supplies (see Carollo, 2019), a revised HAA MCL that encompasses brominated species is not anticipated to result in compliance hurdles for the City.

Chlorate concentrations in UCMR3 distribution system samples collected from areas receiving treated surface water were higher than the 210 µg/L health reference level. If USEPA regulates chlorate, methods to minimize chlorate in Zone 7 surface water supplies may be needed.

WATER SYSTEM MANAGEMENT PLAN 14

4.2 Arsenic Rule
The current MCL for arsenic is 10 µg/L, which was set by the USEPA in 2006. However, OEHHA’s PHG is

0.004 µg/L (SWRCB, 2023). Although the USEPA is not currently reviewing the federal set arsenic regulation, the California DDW is currently reviewing its MCL to see if it technically and economically feasible to reduce the MCL, so the standard is closer to the PHG goal.

Recent data from the City shows that arsenic levels in Wells 5, 6, and 8 are undetectable. However, the City should continue to monitor arsenic water quality data in the groundwater wells.

4.3 Hexavalent Chromium (Cr(VI))
Hexavalent chromium is regulated under the California MCL for total chromium at 0.05 mg/L whereas the federal MCL is 0.1 mg/L. The State of California used to have a specific Cr(VI) of 10 µg/L, but this regulation was invalidated by the Superior Court of Sacramento in 2017. The court found that the MCL was invalid because there was no determination of economic feasibility in the regulatory process. The court ordered SWRCB to write a new regulation for Cr(VI) (SWRCB, 2022).

The City met the state MCL for Cr(VI) when it was in effect from 2011 to 2017. Recorded levels of Cr(VI) ranged from 3.6-5.5 µg/L in Wells 5, 6, and 8. If the new regulation results in a Cr(VI) MCL of 10 µg/L, resulting impacts to the City would be limited to monitoring requirements. However, if the MCL is lowered, the City would need to evaluate treatment or blending options.

4.4 Manganese
The City is currently required to notify and respond to Mn levels of 500 µg/L and 5,000 µg/L respectively.

Additionally, a secondary MCL exists at 50 µg/L, which is based off aesthetic concerns (SWRCB, 2023). In February 2023, the DDW proposed new notification and responses levels for Mn of 20 µg/L and 200 µg/L (SWRCB, 2023). The City does not have detectable levels of Mn in their groundwater wells, so no adjustments are needed to the City’s current treatment for Mn.

4.5 Microplastics
In August 2022, the SWRCB released a handbook which established methods for testing and reporting of microplastics in drinking water. This provides the foundation for Phase 1 of the CA Microplastics Monitoring Program. This is a four-year program for selected surface waters occurring in two phases. The first phase includes collecting four raw water samples per year for two years: two samples in rainy season and two samples during dry season. DDW will present a public workshop for systems required to monitor to be held in May 2023. Phase Monitoring is anticipated to occur 2024 to 2026. Phase 2, hinging on the result of Phase 1 is likely to include treated water sampling.

Groundwater sources are anticipated to be less impacted by microplastics than surface water systems. As a result, the impacts of this future regulation are anticipated to be outside of the planning horizon of this document for the City’s wells.

Zone 7’s surface water supplies will need to monitor, and depending on results, may need to implement improvements.

WATER SYSTEM MANAGEMENT PLAN 15
SECTION 5 CONCLUSIONS AND RECOMMENDATIONS
The City meets all current federal and state primary drinking water standards, with no violations since 1995, close to three decades ago. Several current regulations will require that the City complete steps for continued compliance:
 LCRR. The City will need to complete its LSL inventory (for privately owned portions) and update its lead and copper sampling protocol (i.e., locations to reflect revised tiering structure, use of wide- mouthed bottles, etc.) by October 16, 2024. Additionally, the City will need to comply with the requirements for sampling in schools and childcare facilities, and update communication materials to meet the rule requirements for public education. Based on historical lead and copper compliance data, the City is not anticipated to be impacted by the new 10 µg/L trigger level, but could be subject to find-and-fix requirements for any individual sample results above 15 µg/L.  PFAS. The City will need to comply with the CA SWRCB NLs and response levels for PFAS. Once the USEPA PFAS regulations are finalized, Zone 7 and the City will need to comply with those MCLs / hazard index. For now, the City should inform customers if PFAS levels meet or exceed the notification requirements and continue to monitor and confirm ability to operate Wells 5 and 6 below response levels. Zone 7 is installing treatment to remove PFAS from its contaminated groundwater supplies. The City will need to install treatment to meet CA SWRCB response levels and the USEPA propose MCLs if it elects to continue use of any of its wells.
 CCR. The City will need to comply with the CCR rulemaking once it has been finalized.  GWR. The City will need to complete steps for continued compliance if any new wells are constructed.  Upcoming UCMR 5 Testing
 In the future, if the City modifies its source water and/or treatment (i.e. install new wells, add PFAS treatment, add new Zone 7 turnouts) it should consult with DDW to determine if adjustments to DBP monitoring are required.
 Distribution system water quality data should be carefully tracked for continued compliance. For example, TTHM concentrations have approached the MCL. The City should continue to monitor and manage DBPs in the distribution system. As the City continues to improve disinfectant residuals in the distribution system to help manage nitrification, the nitrification monitoring plan should be updated to reflect modifications and changing conditions.

As a consecutive system, the City will also need to remain vigilant in verifying Zone 7’s continued compliance with all regulations.

Potential future federal and state regulations could lead to additional requirements or steps for compliance:
 M/DBPR revisions. Potential revisions to the M/DBPRs that have been discussed within the NDWAC working group that could impact the City include changes to the minimum disinfectant residual, a chlorate MCL, and any requirements for opportunistic pathogen monitoring. Despite bromide occurrence in some supplies at higher concentrations (see Nitrification Evaluation, Carollo, 2019), the brominated HAA concentrations in City distribution system samples collected for UCMR4 were below 30 µg/L. The City is not anticipated to be impacted by an HAA9 or HAA6Br MCL.

WATER SYSTEM MANAGEMENT PLAN 16
 PFAS. Once the USEPA PFAS regulations are finalized, Zone 7 and the City will need to comply with those MCLs.
 Cr(VI) MCL. The City will need to comply with the Cr(VI) state standard if and when it is established.

Since Cr(VI) concentrations are low in the City’s supplies, compliance will most likely be limited to monitoring and reporting.

Prepared By: Brianna Barton, Tim Loper
Reviewed By: Nicola Fontaine
Subject: Current and Future State of California Water
Conservation Regulations
The purpose of this Project Memorandum is to summarize current and future State of California water conservation regulations to help inform the City of Pleasanton (City) in planning and budgeting for the future.

Current State Water Conservation Emergency Regulations
The State Water Resources Control Board (State Water Board) has two emergency regulations in effect that prohibit certain wasteful water use practices statewide and encourage Californians to use water wisely. Local water suppliers may adopt stricter water conservation measures than the State Water Board.

Refer to Appendix A for a summary of the current State water conservation emergency regulations.

The California Water Code (CWC) requires urban water suppliers within the state to prepare and adopt an Urban Water Management Plan (UWMP), including a Water Shortage Contingency Plan (WSCP), every five years for submission to the Department of Water Resources (DWR). The purpose of the UWMP is to maintain efficient use of urban water supplies, continue to promote conservation programs and policies, ensure that sufficient water supplies are available for future beneficial use, and provide a mechanism for response during water drought conditions. The goal of the WSCP is to have a procedure for managing and mitigating shortages, allowing the supplier to respond in an efficient and timely manner.

The Annual Water Supply and Demand Assessment Report, also known as the Annual Water Shortage Assessment Report, Annual Shortage Report, Water Shortage Report, or Shortage Assessment Report, is due to DWR on or before July 1 of each year as required by the CWC. The annual water supply and demand assessment is a recurring process for determining the supply reliability each year and to prepare suppliers with tools to deal with anticipated water shortages.

html for additional information about current State wate r conservation emergency regulations.

Future State Water Conservation Regulations

drought planning to adapt to climate change. In response, Making Conservation a California Way of Life 1 is the regulatory framework proposed by State Water Board staff. The proposed regulation would require urban retail water suppliers (suppliers) to calculate and adhere to urban water use objectives (objectives), implement commercial, industrial, and institutional (CII) performance measures, and submit annual progress reports.

The proposed regulation is expected to save a significant amount of water and would help to realize California’s Water Supply Strategy
2 goal to reduce annual water demand by at least 500,000 acre-feet by 2030. The proposed regulation will also lessen the need for the emergency water use reduction targets that were important in recent droughts (such as the Water Conservation Emergency Regulations adopted in May 2022 to implement Governor’s Executive Order N-7-22 3 which required suppliers to implement Level 2 actions [up to 20 percent shortage]).

The objective would be calculated as the sum of standard-based budgets for efficient water use (residential indoor use, residential outdoor use, CII landscapes with dedicated irrigation meters (DIM s) or equivalent technology, real water losses), variances (if applicable), temporary provisions (if applicable), and bonus incentive for potable recycled water use (if applicable). Suppliers would need to meet the overa ll objective, not each individual budget. The one exception is the budget for water loss which was set by a separate regulation. Individual households and businesses would not be subject to the proposed regulation. Refer to Appendix B for a summary of the objective components.

Per the proposed regulation, each supplier shall submit the supplier’s calculated objective along with relevant and supporting data no later than January 1, 2025, and by January 1 every year thereafter. The calculation shall be based on the supplier’s water use conditions for the previous state fiscal year.

The proposed regulation provides suppliers with flexibility to implement locally appropriate solutions. To meet annual objectives, suppliers may use a wide variety of tools to encourage customers to use water wisely, indoors and outdoors. Examples include education and outreach, leak detection, rate reform, incentives to plant “climate ready” landscapes, and rebates to replace old and inefficient fixtures and appliances.

Costs to the supplier include development of water reduction strategies, implementation of water use efficiency measures, annual calculation of the objective, preparation of annual progress reports, and lost revenues due to the water use reductions. Additional costs could include wastewater operations and maintenance or wastewater infrastructure improvemen ts due to decreased influent volumes or increased influent concentrations.

Benefits include reduced water purchases or reduced water production, avoided stormwater measures, and energy cost savings. Additional benefits may include protecting human health and water resources, supporting practices that keep trees healthy, mitigating and adapting to climate change, accelerating nature-based solutions, diverting organic waste from landfills, building healthy soils, and advancing equity.

PROJECT MEMORANDUM
DRAFT / 3
The State Water Board has predicted that statewide benefits will outweigh costs but that most of the costs will be incurred in earlier years while most of the benefits will be accrued in later years. Suppliers and wastewater agencies are expected to pass on costs and benefits of the proposed regulation to customers by adjusting their rates to customers over time.

The State Water Board has made a Water Use Objective Exploration Tool 4 available to help suppliers learn
how the proposed regulation may affect urban water use. The tool includes 2017-2021 water use data for suppliers, as well as residential landscape area measurement and annual evapotranspiration and precipitation data provided by DWR. Refer to Appendix C for the tool results for the City of Pleasanton which shows that the City may not need to initially make any reductions to current water use in order to comply with the calculated objective (objective-based total).

Demands excluded from the objective include “other” uses, CII indoor use, CII landscape without DIMs, and apparent water losses which are caused by revenue meter under-registration, water theft and billing errors. Although CII indoor use and CII landscape without DIMs are excluded from the objective, they are subject to CII performance measures included in the proposed regulation. Refer to Appendix D for a summary of the CII performance measures.

The regular rulemaking process for the proposed regulation to Making Conservation a California Way of Life is underway. The notice of proposed rulemaking was released on August 18, 2023, and the first public comment period is open through October 17, 2023. The State Water Board will host a public hearing on the proposed regulation on October 4, 2023, starting at 9:30AM. To watch the meeting, join https://video.calepa.ca.gov/. The hearing will include an overview of the propos ed regulation, the regulatory timeline and process, presentations from interested parties, and opportunity for public comment. The State Water Board will consider adopting the proposed regulation in 2024.

California Water Loss Regulations
The State of California has adopted new regulations focused on water loss for urban water retailers as directed by California Water Code Section 10608.34. The regulations include a formulaic approach to the calculation of urban water retailers water loss standards and the percent reduction targets. The reduction targets are calculated based on a complex set of rules and economic factors as well as agency specific default factors. The economic model incorporates a multitude of inputs into its calculations. The inputs come from City submitted Annual Water Loss Audits, additional data submitted by the City, and factors provided by the State Water Board. The economic model inputs are summarized in Table 1. 4 https://www.waterboards.ca.gov/water_issues/programs/conservation_portal/water-use-explorer/

The City can update the default factors based on a prescriptive approach provided in the regulation documentation.

The economic model is the basis for the development of the benefit cost ratio. The benefit cost ratio is the calculation of the relative value of leak detection and the amount of leakage that can be reduced with a positive net benefit.

Published Water Loss Standards
Based on data provided by the City in it’s annual water loss audits, and the output of the economic model the State has published water loss reduction standards and reduction goals. The standards and goals can be found on the California State Water Board Website 5. There is significant detail related to the calculation of the City’s standards and goals contained in the regulation documentation.

Specific Standards and required reductions for the City of Pleasanton are summarized in Table 2. The City’s current baseline real loss is 30.9 gallons per service connection per day (gpscd). The current standard is 18.8 gpscd, which equates to a 39 percent reduction goal.

Compliance Guidelines and Schedule
The State’s compliance timeline is included in Figure 1. The City’s needs to meet compliance guidelines by January 1, 2028.

Figure 1 – State Water Board Water Loss Compliance Timeline Compliance can be achieved in two ways. The City will need to calculate its real water loss in the annual audits for years 2024, 2025, 2026, and 2027. Real losses are calculated based on the average of three of the four previous years, the highest year can be thrown out. The City will be in compliance by reducing the real loss from the 30.9 gpscd to 18.8 gpscd. If that goal is met, the City would need to maintain a real loss rate that is within 5 gpscd measure every three years to maintain compliance. If the City can’t meet the real loss reduction targets, there is a second compliance pathway. The second compliance pathway is summarized in Table 3 below.

Table 3 – Alternative Compliance Pathway
Compliance Action Notes

1. Alternative compliance pathways obtainable if
real loss goal is greater than or equal to 30%
of baseline.

Currently the City’s goal is 39%

2. Show a 30% reduction in real losses over the
baseline
This is equivalent to a 77% reduction of the
current baseline loss.

3. Water Loss Audit Data Validity Score of 3 or
demonstration of improved data quality.

Consideration will be given to data validity score
reductions related to water audits prepared using
different versions of the water auditing software.

4. Completed one full cycle of leak detection
survey
Would require a complete system survey in a
three year period between 2025 and January. 1

5. City has submitted a written request to follow
the secondary compliance request by January
1, 2028.

Need to include:

1. Reason why City was unable to meet standard.

2. List of leakage prevention activities the City
has engaged in to limit water loss.

3. Demonstrate how the City is being a good
steward of the water code WRT Div 6, 2.25,
Chapter 9. (Sustainable water use and demand
reduction: Urban Water Use Objectives and
Water Use Reporting)

4. A plan for how it will meet its real water loss
standard no later than January 1, 2031.

T
he alternative compliance pathway requires significant effort to achieve, even if the City can’t reach the current standard. With the alternative compliance pathway, the City will still needs to meet its standard by 2031. Essentially the City would have six years to reach the 39% reduction goals.

Water Loss Questionnaires
As part of the regulations, urban water suppliers will be required to submit responses to three questionnaires related to the City’s water loss tracking and data management activities. The list of questionnaires and the submission deadlines are listed in Table 4. The City has missed the deadlines for the Data Quality and Pressure Management deadlines. The details related to the questionnaires can be found in the documentation included in Appendix E.

ater Loss Recommendations
Real water loss, as documented by the State of California can occur in three forms. • Reported leakage that occurs in the form of visible failures over the ground. · • Unreported leakage that is not visible above ground but detectable by surveying the distribution system through specialized leak detection equipment. ·
• Background leakage that is too small to be detected with leak detection equipment but can be reduced by replacing or rehabilitating infrastructure or managing operational pressure.

These forms of real loss can be mitigated through the following methods.

PROJECT MEMORANDUM
DRAFT / 7

1. Active leak detection and repair

2. Timely repair of leaks after identification

3. Pressure management that reduces high pressures or spikes in pressure that strain the distribution system

4. Systematic asset management and replacement through prioritization of mains and appurtenances with the highest rates of leakage.

As required by the regulations The City will need to implement a leak detection program. Pressure management is currently part of the State’s questionnaire and needs to be further investigated. The City is currently developing a City wide asset management plan that will ultimately integrate the water utility. At this point the most important thing is for the City to make sure they move towards compliance.

Implementing a full system leak detection program over the next three years will be critical to finding and fixing leaks, but also will allow the City to achive the alternate compliance pathway in 2028.

Leak Detection
As part of the economic model the State conducted a study of leak detection vendors including costs.

Carollo has also been working with other vendors for other agencies across the Country. The cost for leak detection can be estimated to be approximalty $750/mile. At 295 miles the cost for system wide leak detection could range between $225,000 and $300,000 for vendor costs. Including contingencies the total costs could be $370,00 to $500,000. For budgetary planning purposes, the City should allocate $500,000 as a CIP costs.

Appendix B
Summary of Urban Water Use Objective Components
 Standard-based budgets for efficient water use:
» Residential indoor use.
 The residential indoor use budget is calculated as t he residential indoor standard multiplied by the number of people in the supplier’s service area multiplied by the number of days in the year. » Residential outdoor use.
 The residential outdoor use budget is calculated as the residential outdoor standard (landscape efficiency factor) multiplied by the net evapotranspiration (reference evapotranspiration minus effective precipitation) multiplied by the residential landscape area multiplied by a unit conversion factor. Suppliers may add the volume of water associated with newly constructed residential landscapes to its residential outdoor use budget.
 Residential landscape area includes residential “Irr
igable Irrigated” area plus approved “Irrigable Not
Irrigated area.” “Irrigable Irrigated Area” refers to area presumed to be maintained and managed through active irrigation. “Irrigable Not Irrigated” refers to area that is not currently being irrigated, but was irrigated in the past, or may be managed with irrigation in the future.  Through June 30, 2027, a supplier may include in its residential landscape area up to twenty percent of the supplier’s “Irrigable Not Irrigated” area, if the supplier’s actual urban water use for the reporting year is greater than the calculated objective without inclusion of “Irrigable Not Irrigated” area.  A supplier may, for each reporting year, use and rep
ort an alternative data source for residential landscape area, if it demonstrates to the State Water Board that the data is equivalent, or superior, in quality and accuracy to the provided data.
 “Residential special landscape area” means residenti
al areas dedicated solely to edible plants and
residential areas irrigated with recycled water. If a supplier delivers water to residential special landscape areas, the supplier may calculate its residential outdoor use budget accounting for the residential special landscape area and standard.
» CII landscapes with DIMs.
 Through June 30, 2028, a supplier’s budget for CII l andscapes with DIMs shall be the supplier’s actual deliveries associated with landscape irrigation.
 Beginning July 1, 2028, the CII landscapes with DIMs is calculated as the standard (landscape efficiency factor) multiplied by the irrigated area of CII landscapes with DIMs multiplied by the net evapotranspiration multiplied by a unit conversion factor. A supplier may add the volume of water associated with newly constructed landscapes to its CII landscapes with DIMs budget.  CII landscapes with DIMs that are special landscape
areas includes slopes designed and constructed with
live vegetation as an integral component of stability, ponds or lakes receiving supplemental water for purposes of sustaining wildlife, recreation, or other public benefit, plant collections, botanical gardens, and arboretums, public swimming pools and similar recreational water features, and cemeteries built before 2015.

If a supplier delivers water to CII landscapes with DIMs that are special landscape areas, the supplier may calculate its CII landscapes with DIMs budget accounting for the special landscape area and standard. » Real water losses.
 Distribution system water losses ("real" losses) are the physical water losses from the water distribution system and the supplier's storage facilities, up to the point of customer consumption.  The real water loss budget is calculated as the syst em-specific standard (gallons per connection per day or gallons per mile per day) multiplied by the number of connections served by the supplier (or number of miles) multiplied by the number of days in the year.

PROJECT MEMORANDUM

DRAFT / 10
 Suppliers must comply with individual volumetric loss standards over a three-year period beginning on January 1, 2028. Prior to this, the supplier’s water loss budget may, alternatively, be equal to its previous year’s real water losses reported in its annual water loss audit.  Variances (if applicable).
» “Variance” means an additional volume of water that a supplier may request to add to its objective for a unique use that has a material effect on a supplier’s objective. » Examples include:
 Residential indoor use: Significant fluctuations in seasonal population or significant use of evaporative coolers.
 Residential outdoor use: Populations of horses and other livestock, water for dust control on horse corrals or other animal exercise arenas, water for irrigating agricultural landscapes that are within residential areas but have not been classified as irrigable irrigated, water used to respond to emergency events not including drought, water for landscapes irrigated with recycled water containing high levels of total dissolved solids (TDS), and water to supplement ponds and lakes to sustain wildlife as required by existing regulations or local ordinances.
 CII landscapes with DIMs or equivalent technology: Water used to respond to emergency events not including drought, water for landscapes irrigated with recycled water containing high levels of TDS, and water to supplement ponds and lakes to sustain wildlife as required by existing regulations or local ordinances.
» Most of the time, the associated water use, for any individual variance, must represent 5 percent or more of the sum of the budgets associated with the standards (residential indoor and outdoor use, CII landscapes with DIMs, and real water losses).
» Requests for variances must be submitted to the State Water Board annually by October 1. Requests must include information showing how the request is warranted and protects beneficial water uses, demonstrating that the amount of water requested was delivered by the supplier for the requested use, and verifying that the approval of the request would not jeopardize the ability to comply with existing permit requirements within the supplier’s service area.  Temporary provisions (if applicable).
» “Temporary provision” means an additional volume of water that a supplier may request to add to its objective for a limited time for a specified beneficial use that would require less water over time. » Examples include:
 Residential indoor use: To respond to negative impacts to wastewater collection, treatment, and reuse systems.
 Residential outdoor use: Water for existing pools, spas, and similar water features, water for the planting of new, climate-ready trees, and water for the establishment of qualifying landscapes. Qualifying landscapes are those that require temporary irrigation and are associated with low-impact development, ecological restoration, and mined-land reclamation projects.
 CII landscapes with DIMs or equivalent technology: Water for the planting of new, climate-ready trees and water for the establishment of qualifying landscapes.
» Requests for temporary provisions must be submitted to the State Water Board annually by October 1 and must include the same information as requests f or variances.  The request for temporary provision for residential indoor use must also show to the satisfaction of the State Water Board that meeting the objective would require adhering to the applicable residential indoor standard and that meeting the budget for efficient residential indoor use is causing challenges within wastewater collection, treatment, and reuse systems.

PROJECT MEMORANDUM
DRAFT / 11
 The request for temporary provision for residential outdoor use must also include a description of efforts to prioritize water for existing trees, including, but not limited to rebate, direct install, and educational programs focused on transitioning from turf- to tree-centric irrigation systems that promote deep and healthy root growth. Tree-centric irrigation systems include but are not limited to soaker hoses, deep drip watering stakes, drip tubing, and emitters.
 Bonus incentive for potable recycled water use (if a pplicable). » If a supplier delivers water from a groundwater basi n, reservoir, or other source that is augmented by potable reuse water, the supplier may add to its objective a bonus incentive.  For existing facilities, may be up to 15 percent of objective.  For all other facilities, may be up to 10 percent of objective.

ND 10-YEAR CIP

1.1 Introduction
The City of Pleasanton (City) is in the eastern San Francisco Bay Area region south of Interstate 580, and e
ast of Interstate 680 in Alameda County. The City owns and operates a potable water system that serves residential customers as well as commercial and industrial users within its City limits. The water system is illustrated on Figure 1. City staff recognize the need for a comprehensive water facility condition assessment to develop a 10-Year Capital Improvement Project (CIP). The recommendations will be incorporated into the Water System Management Plan (WSMP).

1.1.1 Objectives
The City’s primary objectives for implementing a condition assessment for the water facilities include:
 Im
proving the cost-effective management of assets thr oughout their life cycle.  Promoting data sharing and interconnectivity within a nd across departments.  Demonstrating fiscal responsibility.
 Identifying and prioritizing projects for the 10-year CIP.

1.1.2 Background
The WSMP is being implemented in three phases:

P
hase 1 consisted of a high-level assessment of the City’s water system program that includes the development of evaluation guidelines, evaluation of the existing performance of the City’s current management of the water system, and identification of short- and long-term priorities for improvement as documented in the Technical Memorandum - High Level Utility Assessment Summary (April 2023) prepared by Carollo Engineers, Inc. (Carollo).

Phase 2 involved reviewing the high-level assessment results and findings of Phase 1 to identify short- and long-term work plan priorities. This resulted in initiating condition assessments of water system facilities in the field and conducting a desktop assessment for the water mains. Additionally, a review of current and upcoming regulations was conducted to identify potential impacts to the City’s water system program. The results of the regulatory review and the condition assessments inform the recommendations to be developed for the initial WSMP in Phase 3.

Phase 3 is the preparation of the initial WSMP. An integral component of the WSMP, is the development o
f activities that support asset management business practices. These activities are documented within this TM and summarized below:
 Water Facility Renewal and Replacement:
» Develop a register of water facility assets.
» Analyze the results of the field condition assessment of water facilities.
» Rank (or prioritize) replacement needs.
 Operations and Maintenance (O&M):
» Recommend a prioritized list of O&M practices and pro gram improvements for managing water
system assets.
 Capital Improvements:
» Recommend and prioritize the next 10-years of capital improvement projects with
implementation cost estimates.

1.2 Water Facility State of the Assets
The City’s water facilities include 14 booster stations, 21 reservoirs, four groundwater wells, and seven t
urnouts that supply the water from Zone 7.

1.2.1 Probability of Failure
The Probability of Failure (POF) is the measure of likelihood that an asset will fail or degrade to a point w
here it is not meeting its required level of service. This section covers the estimated useful life (EUL), the condition of the assets (POF approach) and the results of the condition assessment and estimated remaining useful life (RUL) (POF results).

1.2.1.1 Estimated Useful Life
The EUL is the starting point for understanding the current state of the assets. For above ground assets, a
n EUL value is assigned by asset class based on industry standards and the American Water Works Association (AWWA) Effective Useful Life Tool. The EUL can be adjusted based on conditions that are outside of assumed normal operating conditions. For example, the EUL may be adjusted down if an asset has an unusually high or low number of start and stop cycles. Conversely, an older asset that is performing optimally may have its EUL extended. The EUL by asset class is in Table 1 and Appendix A.

Using the EUL and the age of the asset, which is determined using Equation 1, the RUL, represented in years, can then be calculated as shown in Equation 2. If no installation date is available, then the installation date has been assumed using the facility commissioning date.

The RUL represents an age-based assessment of the assets and is characterized as the time frame by which an asset is expected to need rehabilitation or replacement. For assets that are older than their EUL, the RUL is set to zero. The RUL can also be translated into a percent life consumed by way of Equation 3.

Assets with an RUL value of zero are considered to have 100 percent of their life consumed.

1.2.1.2 Approach
The POF is determined using data collected through field evaluations or, when not available, a desktop evaluation. These evaluations are described as follows:
 Field Evaluations: A physical evaluation of assets in the City including visual interpretation of the general condition, deterioration, components, coating, corrosion, etc. (condition-based approach ).

Additionally, during the field visit, Carollo discipline leads talked to operations staff about asset performance, reliability, O&M, and obsolescence (performance-based approach). The field evaluations occurred September 29, 2022, and October 5-6, 2022; and May 11-12, 2023 and May 18, 2023, by Carollo discipline leads for electrical, mechanical, and structural assets.  Desktop Evaluation: A RUL evaluation of the assets using available attribute information and the EUL as determined by asset class (age-based approach). This approach is used where a field evaluation was not conducted.

For both evaluations, a POF score on a scale of one to five is assigned to each asset. This score is defined in Table 2.

For field evaluations, the score POF score assigned in the field can be translated to a percent life consumed. For desktop evaluations, the percent life consumed that is calculated based on asset age and EUL can be translated to a POF score. In this way, assets can be compared using the same system whether they were evaluated in the field or on a computer. Figure 2 shows how the score can be translated to a percent life consumed, or vice versa, for assets using the upper value of each range listed in the table above.

65 – 79 3 Fair: Asset has significant defects that will affect reliability or efficiency. 80 - 89 4 Poor: Asset is highly unreliable or inefficient. 90 - 100 5 Very Poor: Asset is no longer able to function in its current condition.

Figure 2 Translating Percent Life Consumed and POF Score When the RUL is calculated from a POF score, we call it an evaluated RUL (evRUL) estimate. The evRUL, represented in years, is calculated using Equation 4.

Equation 4
( = % 



 × 
The evRUL is the result of the percent life consumed (from Table 2) and the EUL. The EUL value is assigned by asset class. The evRUL plus the current year (2024) is then used to determine the reinvestment year timing for the asset as shown in Equation 5.

Equation 5

Field Evaluations
For assets that have been evaluated in the field (i.e., through condition assessments, inspections, or other tests), a condition-based assessment POF score is used. This score is determined in the field by condition assessment discipline leads. The lead scores the asset based on discipline specific criteria for condition 1 2

Using the maximum score (rather than the average) provides conservative results because this approach includes all assets in need of attention that might otherwise be lost due to averaging. This is import ant for identifying assets and issues that represent a high risk due to the POF score. In some cases, the cost to improve an individual POF score may be minor yet could have a significant impact on reducing risk.

The
CONDITION SCORE is determined by the discipline lead scoring the asset on a one to five scale for the categories in Table 3. The condition question categories vary by discipline.

The
PERFORMANCE SCORE is determined by the discipline lead scoring the asset on a one to five scale using the following categories:
 Performance.
 Operations and Maintenance.
 Reliability.
 Redundancy.
 Obsolescence.
 Estimated Life Remaining.

The scores for performance, O&M, reliability, and obsolescence are incorporated into an overall performance score as shown in Equation 8:

Redundancy is captured for documentation purposes a nd the estimated life remaining is used for quality assurance/quality control (QAQC) purposes. Assets with significant differences between the estimated life remaining observations and the replacement timing results are flagged for further review.

Desktop Evaluation
For assets not evaluated in the field, an age-based desktop evaluation is used to calculate the POF score using the installation date and its EUL to calculate the POF score (i.e., the POF score is determined using equations 1 through 3), then the percent life consumed is translated to a POF score as shown in Figure 3.

14 The condition-based POF evaluation method (field ev aluation approach) provides a more representative assessment because of the nature of the POF score b eing based on visual observations of the asset, as well as feedback from staff on the asset performance. Nevertheless, it is not always practical to visually assess every asset. Hence, the age-based POF evaluation method (desktop evaluation approach) is useful in providing a generally conservative estimate for projecting asset replacement timing.

1.2.1.3 Results
POF scores are identified for each asset using field evaluation (condition-based and performance-based ) results, or, if not available, desktop evaluation (age-based) results.

Across the water facilities there are 525 assets included in the assessment. Of those assets, 452 were assessed using condition information derived from a visual inspection and the remaining 24 were assessed in the desktop evaluation because they were unable to be accessed. The combined evaluations have resulted in a POF score for each asset, which is shown in Figure 4.

Figure 4 Water Facility POF Scores
Over 75 percent of assets are in good (score of one), acceptable (two), or fair (three) condition. Typically, these assets do not need immediate attention and are operating as desired with a few recommendations for improvement (namely for assets with scores of three). On the other hand, almost a quarter of asset s are in poor (four) or very poor (five) condition indicating that reinvestment is needed now or very soon.

Of the 75 assets assigned very poor condition scores, 35 were assigned a score of five through the age-based evaluation. The age-based evaluation repr esents six percent of all the assets, but nearly 44 percent of the assets with a score of five. This example helps demonstrate the variability between the desktop and field evaluations. The findings from the field are generally better than the desktop POF scores. This indicates that the assets are well maintained and appear to function well despite their apparent age. Some methods that will improve the desktop evaluation results in the future are to use accurate asset installation dates, consider additional factors (i.e., O&M history) that may impact the EUL, and updating EULs.

15 The POF score and EUL for each asset were used to calculate RUL and associate each asset to a reinvestment year. Figure 5 presents the number of assets by reinvestment year.

Figure 5 Water Facility Assets by Reinvestment Year
The earliest reinvestment year represented is 2024, if there were any recommendations that occurred before 2024, they were reassigned to 2024.

The following sections take a closer look at the results by facility. For a list of all assets by site and their POF score, reinvestment timing, and any observations and recommendations refer to Appendix B.

1.2.2 Consequence of Failure (COF)
COF represents the relative impacts to the City if an asset were to fail (i.e., a higher COF score indicates greater repercussions).

As part of the City’s AWIA Risk and Resilience Assessment (RRA), consequence metrics of low, medium, o r high were assigned to eight categories that represent relative financial, social, and environmental ef fects of an asset or system failing for each facility location:

1. Financial losses to the utility.

2. Economic losses to the community.

3. Impacts to essential critical infrastructure (non-agency).

4. Impacts to the environment.

5. Impacts to water quality.

6. Impacts to public confidence.

7. Fatalities.

8. Serious injuries.

CITY OF PLEASANTON

WATER SYSTEM MANAGEMENT PLAN
39 Building on the eight RRA categories above, a ninth one was established for this effort to capture operator input. Operators’ firsthand experience makes them invaluable in identifying areas where capital investments can yield the most significant improvements. The operator input was discussed and assigned at the Water Asset Rehabilitation and Replacement (R&R) Workshop on April 30, 2024. The workshop materials are in Appendix C.

9. Operator input.

The consequence metrics for the water facilities represent the worst reasonable consequences resulting from the destruction or loss of each facility. For each facility, it was determined if the destruction or loss of the asset has a high, medium, or low potential to cause the associated consequence. These are further defined as follows:
 High - The destruction or loss of this asset has a high likelihood of causing the consequence.  Medium - The destruction or loss of this asset has a medium likelihood of causing the consequence.  Low - The destruction or loss of this asset has a low likelihood of causing the consequence.  N/A - This consequence is not applicable to the asset.

The sum of the consequence among the categories was used to represent the COF score where a COF score of 1 represents low, a COF of 2 represents medium, and a COF score of 3 represents high. The COF categories and consequence metric assignments were developed in 2020 by the City and West Yost are provided as Appendix D and in Table 4.

The total COF score by facility is presented in Figure 51.

43 1.3 Water Facility CIP and O&M Investment Strategies The CIP investment strategy is a plan that outlines a water utility’s capital improvement needs and spending priorities over a 10-year horizon that should be updated on an annual basis to reflect changi ng conditions and priorities. The O&M investment strategy is a plan that outlines a water utility’s spending on the O&M of its infrastructure and typically occurs on a 1–3-year basis. Both strategies are based on the current state of the assets.

CIP and O&M investment strategies are complementary and should be developed in a coordinated manner. CIP investments can help to reduce O&M cost s over the long-term by improving the efficiency and reliability of infrastructure. Moreover, inadequate O&M investment can lead to increased infrastructure deterioration and higher CIP costs in the future.

Costs have also been developed at the asset level so that the City can make informed decisions for R&R based on available resources. The following sections identify the cost estimating methodology, and the capital improvement and O&M investment strategies.

1.3.1 Cost Estimating Methodology
This section describes how the costs were developed for the water facilities.

1.3.1.1 Water Facilities
Material costs were assigned at the asset class level using the replacement cost ranges in Table 5.The replacement cost range was determined by Carollo’s discipline leads that participated in the field assessment and from Carollo’s in-house references for material costs from previous studies, projects, and vendor quotes. Appendix A shows the replacement cost range and assumed cost by asset class.

Table 5 Replacement Cost Ranges
Replacement Cost Range Assumed Material Cost (1)
(1) <$5,000 $2,500.00
(2) $5,000-$9,999 $7,500.00
(3) $10,000-$49,999 $30,000.00
(4) $50,000-$99,999 $75,000.00
(5) ≥$100,000 Asset Specific
Notes:
(1) Cost assumed for calculation may vary by asset type.

1.3.1.2 Planning Level Cost Markups
Cost markups were applied to the replacement cost assignments to develop Class 5 planning level estimates per the Association for the Advancement o f Cost Engineering (AACE) definitions of the five class

WATER FACILITY CONDITION ASSESSMENT AND 10-YEAR CIP
OCTOBER 2024 / DRAFT / CAROLLO

CITY OF PLEASANTON

WATER SYSTEM MANAGEMENT PLAN
44 estimates. The resulting AACE class 5 estimates may represent an overestimate of cost by 100 percent or an underestimate of cost by 50 percent. The markup categories are in Table 6.

Table 6 Indirect Cost Factors
Markup Category Percentage of Direct Cost Total
Installation 70 percent
Direct Cost Multiple (1) 1.70
Owner’s Costs 30 percent
Subtotal Multiple (2) 2.21
Design/Construction Contingency 30 percent
Total Estimated Construction Cost Multiplier (3) 2.87
Notes:
(1) Direct Cost Multiple: 1*1.70=1.70.
(2) Subtotal Multiple: 1.70*1.30=2.21.
(3) Total Estimated Construction Cost Multiplier: 2.21*1.30 = 2.87.

The table above demonstrates how to calculate the total estimated construction cost. Note that if the recommendation is to decommission the asset, then the material cost is $0; however, the installation cost is still based on the cost range for said asset class.

The construction cost also accounts for the owner’s costs. These are the amounts included in the total program budget to cover the owner’s expenses for en gineering fees, legal fees, and the owner’s internal administrative expenses. These costs may also include property/easement/right-of-way (ROW) acquisition, bid advertising, etc., and can range from 15 to 40 percent of the total construction cost. For this project, we are assuming 30 percent.

1.3.2 Capital Improvement Strategies
Establishing CIPs is a key component of a CIP investment strategy because they are long-term plans for construction, rehabilitation, and replacement of infrastructure assets. CIPs through 2034 were identified using observations from the field condition assessments and asset management analyses. Table 7 includes the prioritized list of CIP projects. These projects were identified and prioritized at the R&R Workshop based on the current state of the assets.

Notes:
(1) Rounded to the nearest thousandth.
(2) Consider upsizing pump capacity to split Bonde Zone into smaller zones as desired by operations. Refer to Appendix I in the AKEL report.
(3) Wells 5 and 6 can be decommissioned when the Zone 7 project is completed. (4) Grey Eagle is assumed to not need to be rehabilitat ed; however, if the Grey Eagle Connection to Kottin ger Pressure Zone project does not occur in a timely manner, then reh abilitation of the pump station will be needed.

The total 10-Year CIP cost is nearly $21.4 million. Figure 52 is a graphical representation of the 10- year CIP forecast for water facilities. The breakdown of the assets within each project are in Appendix E. Note that the project year may change based on the timing of related projects and available resources.

Figure 52 10-year Capital Improvement Plan for Water Facilities The 10-year CIP list also considered whether R&R needs are or will be addressed in other projects. These considerations are as follows:
 Turnout 1 R&R will be addressed during the Regional Project. The Regional Project also includes funding for a new turnout.
 Turnout 4 R&R will be addressed during the current Interim Project.  Generator deficiencies are identified in the Generator Report and are to be replaced in the Generator Improvements Project identified in the WSMP.
 Capacity issues identified in the AKEL report for Tanks 550 and 770 are addressed in the Tank 510 Storage Capacity Increase and Tank 770 Storage Capacity Increase projects identified in the WSMP.

CITY OF PLEASANTON

WATER SYSTEM MANAGEMENT PLAN
46 These projects should also consider the O&M needs a nd include asset R&R at these sites where needed.
 PLCs should be replaced in facility rehabilitations; however, if not addressed in a timely manner, the n a PLC replacement project is needed.

1.3.3 O&M Investment Strategies
O&M investments are essential for keeping a water utility's infrastructure in good working order, so the City can continue to deliver reliable service to their customers. They may include activities such as preventative maintenance and corrective maintenance.

The R&R needs that are not captured in the 10-Year CIP are addressed as O&M R&R needs. Figure 53 shows the projected O&M needs over the next ten yea rs based on the current state of the assets. The cost is estimated to be $12.8M. Refer to Appendix F for list of assets included in the O&M forecast.

Figure 53 10-Year O&M Plan for Water Facilities

1.3.4 Next Steps
For the water facilities, the City should continue to refine the recommendations in the 10-year CIP. Next steps include reviewing and refining the proposed projects, defining and prioritizing the projects by risk, and developing a budget for implementing the CIP. It is important to monitor the CIP implementation progress and routinely re-evaluate project needs and priorities as asset condition changes and areas o f improvement are identified.

Operator input line added to AWIA COF scores to adjust the sum (COF). Booster stations and reservoirs should be treated separately.

Water Facilities – Wells

1. Assume that the Zone 7 project will be done. It is already on the CIP list. a. Then Wells 5 and 6 can be decommissioned.

2. ACTION: Rank all wells as lowest COF (7) under the assumption they should all be decommissioned.

Water Facilities – Turnouts

1. Turnout 1:
a. Project: Regional.
i. The reg. project also includes a new turnout.
ii. Add footnote to CIP about regional project.

2. Turnout 2: Not being used. It is a back-up to Turnout 4. Hydraulically the station does not perform. a. Project: N/A.
b. ACTION: Lowest COF (7).

3. Turnout 3:
a. Project: O&M.
b. There is a recommendation to replace the chemical metering pump with a peristaltic pump. However, the City cannot identify a manufacturer of peristaltic pumps that has tubing appropriate for acid (H2S).

4. Turnout 4:
a. Project: Interim.
i. Total rehabilitation project occurring now. Includes two new tanks, chemical system, etc. Adams is the contact.

5. Turnout 5:
a. Project: O&M.
b. ACTION: Highest COF (1).

6. Turnout 6:
a. Project: O&M.
b. ACTION: Follow Turnout 5 in COF ranking (2).

MEETING MINUTES

4 7. Turnout 7:
a. Project: O&M.
b. ACTION: Follow Turnout 5 in COF ranking (2).

Water Facilities – Reservoirs

1. All recommendations for reservoirs should start with an inspection project. a. ACTION: Create a CIP project for the structural internal inspection of reservoirs. Can also create a tank rehab project placeholder based on outcome of inspection.

2. There is a reservoir that has cathodic issues.
a. ACTION: Ryan will talk to Robert to ID site and review if there are any other CIPs needed at reservoirs.

Tank 1300

1. The interior of the tank is concerning. There is a recommendation from the state to rehabilitate this site based on diving footage from an inspection of the interior of the tank and review of the vapor zone. High priority.
a. Project: 10-Year CIP.
b. ACTION: Update POF score to reflect interior condition of the tank.

Capacity Issues - Tanks 510, 770

1. AKEL report found that these two zones have an existing deficiency of insufficient capacity (need storage improvements). Both tanks are 0.25 MG. The current budget is $2.1M. a. ACTION: Tim to review budget with AKEL. The cost should be for a new tank and include rehabilitation of other assets (valve vault, etc.).
b. Project: 10-Year CIP (based on capacity).

2. Vault at 770 that needs to be replaced is not a CIP project in itself.

Kilkare Tanks

1. Fire flow concerns are related to the piping and not the tanks. a. ACTION: Update finding in report.

2. Tanks 1160 and 1600 have no power source and rely on batteries. City would like to have a solar panel project to address lack of power. This is also in the energy recommendations (a wishlist project). a. ACTION: Add to project list in condition assessment report.

McCloud

1. Safety concern. Additionally, have received multiple calls this year regarding concerns about the tank in relation to buying a house in the area.

2. Project: Decommission.

MEETING MINUTES

5 Water Facilities – Booster Stations
Grey Eagle

1. Small service area, antiquated station (was supposed to be temporary), hydropneumatics issues (refer to AKEL report).

2. Site can be decommissioned with CIP project to install a pipeline to Kottinger Ranch and a PRV. a. Project: Decommission.
b. Add footnote to CIP: Grey Eagle is assumed to not need to be rehabilitated; however, if pipeline project does not occur in a timely manner, then rehabilitation of BS will be needed.

Vineyard

1. Supplemental LS only.

2. Need pump capacity improvements at this site to be able to split up the megazone (refer to Appendix I in the AKEL report).
a. Add footnote to CIP: Consider upsizing pump capacity to split Bonde Zone into smaller zones as desired by operations.

3. Project: Full rehabilitation project needed.

Laurel Creek

1. Have had issues with this BS. Needs a new generator and many electrical findings.

2. Project: 10-Year CIP.

Longview

1. BS rehabbed 12 years ago. The reservoir was rehabbed 3-4 years ago.

Foothill

1. Average POF: 3.35.

2. Site does have redundancy (can be fed water from elsewhere). Start of the daisy chain.

3. Project: 10-Year CIP.

Ruby Hills

1. ATS replaced already.
a. ACTION: Update findings.

2. Shed at Upper Ruby Hills Reservoir is an O&M project.

Vineyard Hills

1. The motor control valve vaults were flooded out and are currently not functioning. a. ACTION: Add to condition assessment report.

Kottinger Ranch

1. Average POF: 2.75

2. COF will increase if Grey Eagle is decommissioned. Would like 3 pumps because 2 are needed during peak demand. Not in AKEL report. Pump info used for report may not be correct.

3. As critical as Foothill and Grey Eagle?

4. MCC from the 70s. Ready for CIP.

MEETING MINUTES

6 Other
Generators

1. Need generator project that is supported by project memo. Todd to send so it can be incorporated into the findings. Lots of recommendations (mostly regarding portable generators).

2. Currently renting generators, which has been costly.

3. Non-compliant with permits and insufficient for PSPS (category A in priority). a. ACTION: Add to CIP.

PLC

1. Add footnote to CIP: PLCs should be replaced in facility rehabilitation; however, if not addressed in a timely manner, then a PLC replacement project is needed.

Water Loss

1. Conservation memo. Tim provided the water loss presentation to Todd. City needs to add leak detection program.

Next Steps

1. Prepare updated Water Facility Condition Assessment TM which will include projects discussed in this workshop, and updated costs.

Worst Reasonable Consequences:

Estimate the worst reasonable consequences resulting from the destruction or loss of each asset, without regard to threat. For each of the assets, determine if the destruction or loss of the asset has a high, medium or low potential to cause the associated consequence. Enter H, M or L in the cooresponding cells. :
1) High - (H) The destruction or loss of this asset has a high likelihood of causing the consequence. Quantitative score: 3. 2) Medium - (M) The destruction or loss of this asset has a medium likelihood of causing the consequence. Quantitative score: 2. 3) Low - (L) The destruction or loss of this asset has a low likelihood of causing the consequence. Quantitative score: 1. 4) N/A - (N) This consequence is not applicable to the asset. Quantitative score: 0.

Prioritize the critical assets using the sum of the estimated consequences. The sum of the associated quantitative score can be found in column I. The higher the score, the more critical the asset.

CITY OF PLEASANTON
WATER SYSTEM MANAGEMENT PLAN 4
SECTION 1 INTRODUCTION
The City of Pleasanton (City) is in the eastern San Francisco Bay Area region, south of Interstate 580, and west of Interstate 680 in Alameda County. The City owns and operates a potable water distribution system that serves approximately 80,000 residential customers as well as commercial and industrial users within its city limits. The City staff recognizes the need for a comprehensive evaluation of the current operations and management of the water system and selected Carollo Engineers (Carollo) to perform an assessment of the water system program. The evaluation not only includes a review of the operations of the water system, but also the City’s ability to deliver potable water to customers at an adequate supply and pressure, implement capital improvement programs, communicate with internal and external stakeholder groups, finance existing and future operations and capital improvement projects, and predict and analyze the risks from existing and future regulatory drivers.

This technical memorandum reviews current operations, maintenance and management of the City’s water distribution system. The memo reviews current practices using industry standards and includes recommendations to improve water distribution maintenance and water quality.

SECTION 2 DISTRIBUTION SYSTEM CHARACTERISTICS
The City of Pleasanton receives treated water from Zone 7 and treats its own groundwater wells operated by City staff. The sources of supply are included in Error! Reference source not found.. A map of the City's distribution system is shown in Figure 1. The figure shows the location of the City's turnouts where Zone 7 water is delivered, the City owned wells, the storage tanks, and key distribution sample locations.

SECTION 3 DISTRIBUTION SYSTEM MAINTENANCE
This section focuses on a non-regulatory potable drinking water system using best practices and current levels of maintenance. A note of some of these maintenance activities are reported in the City’s annual report to the State Water Resources Control Board Department of Health Services.

3.1 Valve Exercising, Main Flushing and Hydrant Maintenance Per the City’s revised water supply permit approved by the Department of Health services dated October 1997, “The City of Pleasanton shall conduct a program of regular valve exercise and maintenance to ensure the reliability of the distribution system. The City of Pleasanton shall conduct a program of regular distribution system flushing to maintain the quality of water delivered to the distribution system.”
An annual unidirectional distribution system flushing is performed to maintain water quality by scouring pipes surfaces to remove loose sediment, biofilm and scale. Unidirectional flushing is a planned, organized, sequential technique that begins from a clean starting point moving which minimizes the spread of sediment and higher velocity flow. Flushing will lower disinfectant demand, heterotrophic bacterial counts and concentrations of disinfection byproducts.

Figure 2. Examples of Unidirectional Flushing Program Zones To minimize water quality complaints and optimize staffing, water distribution valve exercising, unidirectional flushing and hydrant maintenance activities are often completed simultaneously.

Public notices are provided prior to flushing as sediment and color complaints are common. On-site dechlorination is required and storm drain maintenance crews should be notified prior to starting.

GIS based hydraulic mapping software programs are available to develop scheduled distribution system maintenance and provide detailed mapping for field use.

WATER SYSTEM MANAGEMENT PLAN 7
Water main flushing programs consist of closing system valves and directing flows to obtain minimum of 2.5 ft/sec velocities, or greater and minimum flows per Figure 2. Hydrants can be inspected for flow and mechanical issues at time of flushing. Distribution system flushing is accomplished during low water demand months due to the amount of water required.

Figure 3 Minimum Flushing Velocities for Water Mains
The City GIS contains valve, water main and hydrant locations. The GIS system is a key for developing a unidirectional flushing plan and should be updated annually. The City is currently flushing dead ends on a needed basis to prohibit nitrification. The key to a valve exercising, hydrant maintenance, and flushing plan is a goal. The goal must be manageable given staffing levels and the size of distribution system. The program sets a goal for the number of transmission valves/hydrants to be exercised based on the percentage of total valves/hydrants in the system. The entire system flushing plan could take years to complete due to seasonal capacity restraints. The capital improvement plan (CIP) includes annual valve repair and replacement funding for valves/hydrants identified during the flushing program.

3.2 Potable Water Storage Tank Inspections
American Water Works Association (AWWA) recommends dewatering, diving or Remote Operated Vehicle (ROV) tank inspections every five (5) years. Tanks should be cleaned a minimum of every 5 years or as inspection dictates. Steel tank coating inspection results are evaluated against the current coating system design parameters per AWWA D102-21 to determine the lifespan of the coating. Annual tank inspections include a full external visual inspection seasonally to assess and repair external damage and verify integrity of vents, screens and security. Impressed current cathodic protection systems in storage tanks are recorded monthly and inspected annually. Failure to monitor current levels can cause premature coating and steel failures.

WATER SYSTEM MANAGEMENT PLAN 8

Figure 4 Foothill Water Storage Tank
The City routinely inspects potable water storage facilities according to AWWA standards through diving and visual inspections. Once the inspection video and report are final, the City currently has no mechanism to convert these findings to a capital improvement plan. Failure to recoat water tanks as needed leads to costly structural rehabilitation or replacement and degrades water quality. Integrating an operations and maintenance plan for a cathodic protection system for both potable and recycled systems should be addressed.

3.3 Preventative Maintenance Program (CMSS)
Every well managed utility includes a preventative maintenance program, often in a software format such as a CMSS system. These programs require input from the manufacturer’s O&Ms, historical system knowledge and industry standards. The program disseminates work orders for reoccurring maintenance and can log emergency responses to water leaks, pump station failures, etc. The number of water main leaks and repairs are calculated annually and reported to the SWRCB as part of the annual water system report. The CMSS assists in workload management and staffing deficiencies.

Pump station maintenance, hydrants, tanks, wells and water main replacement schedules are included in the CMSS. Each utility should include system maintenance in the annual operating budget allowing funding for routine and emergency repairs.

3.4 Residential and Commercial Meter Calibration Program The City currently has over 23,000 residential water meters and commercial meters. The backbone of the water enterprise fund depends on accurate billing and collection. The meter calibration program ensures residential and commercial billing is accurate and defensible. Large meters should be calibrated biannually, and residential meters should be calibrated according to the manufacturer’s recommendations.

DISTRIBUTION SYSTEM MAINTENANCE

CITY OF PLEASANTON
WATER SYSTEM MANAGEMENT PLAN 9
Utility testing equipment is often capable of testing higher flow rates, such as commercial meters. A third- party contractor is the most cost-effective method to calibrate lower flow residential meters. All fire- service meters should be tested by a third-party contractor due to fire insurance requirements.

Record keeping is the critical component of a meter calibration and replacement system. Technicians, working with billing staff to identify abnormal monthly meter readings, is the number one reason for meter replacements. The water maintenance budget should include annual funding for maintenance and replacement of a percentage of residential and commercial water meters. Recording monthly meter readings will reduce water loss for rate payers and utility by identifying system leaks and large water users.

3.5 Energy Management Program
The City should have a robust energy management program to review and optimize energy usage at the pump stations and wells. The following are elements of a robust energy management plan.  Identification of energy use trends and cost tracking versus time.  Consideration of energy efficiency and costs in the evaluation of new distribution system facilities.  Changes to the existing system to enhance effective utilization of energy.  Record keeping for future federal and state energy grants.

The energy management system can be a simple recorded history of usage, trends and optimization plans. Other methods include a SCADA based energy management system that tracks energy usage in real time. This system will allow for the largest payback with the ability to optimize based on the electrical utility rate schedule.

3.6 Pipeline Rehabilitation and Replacement Program
Per AWWA and RWQCB operation and management standards, each utility shall have a program for evaluating and upgrading water distribution pipelines. Historically, pipelines have long life spans but are expensive to replace and are critical to maintaining water quality and fire flow standards. Below are the keys to a rehabilitation and replacement program for pipelines.

1. Base prioritization of transmission and distribution mains on critical infrastructure matrix. Which pipelines affects the most residents, firefighting capabilities and water quality.

2. Track water main breaks by area, size, pressure zone and soil type. Establish an annual tracking of benchmarks based on breaks/100 miles/year of distribution pipe.

3. Keep accurate electronic as-builts. Electronic as-builts can be utilized by multiple field crews during emergency or routine operations. Annually updating water modeling software and GIS systems are critical to maintaining distribution infrastructure.

4. Record flow and pressure readings during unidirectional flushing periods. Historical records can determine problem areas before a catastrophic water main break.

SECTION 4 CONCLUSIONS AND RECOMMENDATIONS
The City desires to develop a distribution maintenance program that meets industry standards. One of the critical components to a successful maintenance program is the staff’s ability and desire to implement change. The recommendations are based on short- and long-term goals with an idea to build program momentum as additional funding and staffing are available.

Short Term Recommendations

1. Develop a single unidirectional flushing program section map with clean water source identified. Start in the first area closest to a clean water source. Using the new water model, identify valves to close to achieve 2.5 ft/sec and desired flow rates. Perform the flushing, valve exercising and hydrant inspections in this area. Record findings and notes for developing full unidirectional flushing program software. Identify staffing levels required, traffic control, public notification, and tools and equipment required.

2. Implement a commercial water meter testing section with equipment and record keeping capabilities. This team should work closely with water billing to determine inconsistent metering locations and focus initial testing.

3. Select a well and potable water pumping station to implement a monthly, quarterly, semi annual and annual maintenance program. Record all maintenance activities to include tasks required, number of staff to complete each task, number of hours to complete each task and record keeping. This can be used as a “template” to design a full CMMS maintenance program for all facilities and aid in utilities staffing plan.

4. Develop a standard management matrix for identifying planned and emergency projects, mechanism for budget inclusion, and responsibility for project completion.

Long Term Recommendations

1. Develop a multi-year capital improvement program for unidirectional flushing software, tools, equipment and staffing to implement. Design and procure unidirectional flushing software program and continue water distribution GIS data entry.

2. Develop a capital improvement program to staff and equip a water meter section to test all commercial meters annually.

Solicit bids for third party residential water meter testing over multiple years as funding allows based on industry standards.

3. Procure a CMMS maintenance program for all water distribution mechanical locations.

Recommended staffing include a dedicated administrative position for record keeping and data input.

4. Implement an energy consumption record for each large electrical demand location in the distribution system. Work with local electrical utility on large user energy management plans which target peak cost reductions.

5. Develop a long-term staffing plan incorporating new maintenance programs, software and financing.

6. Develop a pipeline rehabilitation and replacement program utilizing water modeling software and GIS to identify capital improvement projects.

Subject: Nitrification Evaluation

1.0 BACKGROUND
Carollo Engineers (Carollo) evaluated nitrification in the City’s distribution system as part of the Water Supply and Distribution Facilities Improvements Project (Project). The results of the nitrification evaluation are summarized in Technical Memorandum 2 – Nitrification Evaluation (Carollo, 2020). Recommendations and the status of each are summarized in Table 1.

Table 1 Nitrification Evaluation Recommendations

2.0 PROGRAM RECOMMENDATIONS
One of the key recommendations was to install chloramine boosting systems at the Foothill and Sycamore Reservoirs to allow the City to reduce the frequency of tank cycling currently required to maintain residuals in the distribution system. These systems allow both sodium hypochlorite, which is generated onsite, and liquid ammonium sulfate (LAS) to be dosed to maintain target chloramine residuals in the No. Recommendation Status 1 Develop a long-term nitrification monitoring plan. Implemented as part of a future project. 2 Develop a hydraulic model of the distribution system. Completed in 2023. 3 Install residual control systems in the Foothill and Sycamore storage tanks. Completed in 2022. 4 Improve chemical feed control and increase chloramine dose at the City’s wells. City’s wells are not operational due to PFAS concentrations above the MCL. Chemical feed and Chloramine residual will be optimized as part of ongoing regional well project. 5 Increase chloramine residual form Zone 7’s groundwater supply. Zone 7 began increasing the residual in the groundwater supply in January 2020. 6 Develop a nitrification response plan. Preliminary plan completed in 2020 and updated in 2022. Finalized as part of a future project.

storage reservoirs. These systems also consist of monitoring equipment with control algorithms to monitor and maintain the target residual without exceeding a 5:1 Cl2/N ratio.

The RCS systems are set to maintain chloramine residuals between 2.5 and 2.75 in both the Foothill and Sycamore Tanks. Data from the distribution system before and after the RCS systems began operation were analyzed. Distribution system residual data is compared in Figure 1 – Figure 3 for three different time periods:
 Average residuals between January 2019 and April 2019 are shown in Figure 1. During this time period, a high percentage of groundwater was supplied at the turnouts by Zone 7 and the City’s wells were also online. This resulted in low residuals across the system since chloramine decay in the local groundwater supplies is more rapid than in the surface water supplies.  Average residuals between April 2019 and March 2020 are shown in Figure 2. During this time period, Zone 7 provided a high percentage of surface water to the City’s turnouts and the City’s wells were online. Comparing this data to Figure 1 illustrates the impact of Zone water supply (majority surface vs. majority groundwater) on chloramine residuals in the City’s distribution system. Residuals were higher across the distribution system, but still low near the storage tanks.  Average residuals between April 2023 and September 2023 are shown in Figure 3. During this time period, the RCS in the Sycamore and Foothill tanks were operational. Since consistent operation of the RCS began in 2023, residuals have increased in the distribution system, particularly near the foothill and sycamore storage tanks. The RCS systems have also allowed the City to reduce the frequency of tank cycling required to maintain distribution system residuals.

Weekly fill and drain cycles are used in the lower zone to reduce the water age in the storage tanks. Prior to RCS installation, the tanks were cycled from 6 feet to 25-28 feet. Current operations, with the RCS systems in service and the City’s wells offline, tanks are cycled from 18- 25 feet.

Figure 1 Average Distribution System Residuals (January 2019 – April 2019)

Figure 2 Average Distribution System Residuals (April 2019 – March 2020)

Figure 3 Average Distribution System Residuals (April 2023 – September 2023) Implementation of the RCS systems in the Sycamore and Foothill Tanks was effective at increasing distribution system residuals and decreasing the tank cycling required. These installations are currently temporary and housed in trailers. It is recommended that these installations be upgraded to permanent installations.

A majority of the recommendations listed in Table 1 have been implemented since the completion of the Nitrification Evaluation in 2020. Based on reviewing distribution system residuals, the residuals have increased since the implementation of the RCS in the Sycamore and Foothill Tanks. The City also now has

a working hydraulic model to estimate source water blend (Zone 7 vs. City wells) and water age.

Therefore, it is recommended that the City develop a formal nitrification monitoring and response plan that incorporates these changes. The plan should:
 Define monitoring frequency and locations for key water quality to track nitrification.  Update and expand the preliminary response plan previously developed.  Incorporate detailed plans and monitoring strategies for free chlorination of areas of the distribution to manage nitrification.
 Consider the installation of tank mixers in the upper zone reservoirs.

Subject: CIP Rate Implementation Strategies

1.0 BACKGROUND
The City of Pleasanton (City) as part of the Water System Management Plan (WSMP) has identified both Capital and O&M projects and programs that have been recommended for the improvement and enhancement of the City water system utility operations. Critical to the implementation of the Capital and O&M projects and programs is the coordination with the City’s rate consultant on the development of varying phased CIP program costs scenarios. This project memorandum summarizes the CIP and O&M recommendations, and three phased funding scenarios as well as a qualitative assessment of the pros and cons of each alternative.

2.0 CAPITAL PROJECTS
The Capital projects have been developed based on multiple assessments conducted by the City and as part of the WSMP. The CIP projects have been prioritized based on three priority definitions.

1. Priority A – These projects are ranked the highest if they are required for health and safety; required by law, regulation, or contract; are under construction; and/or are funded by applicants or outside funding source
.

2. Pr
iority B – These projects are those that provide measurable progress toward achieving the City’s goals, but the City has a moderate level of control as to when these projects should be accomplished.

3. Priority C - Projects not meeting the criteria for priority level A or B are ranked as priority level C.

These are projects that are anticipated to be needed, but may not yet have defined scopes and schedules.

The projects have also been categorized based on specific facility categories including:

1. Water Supply.

2. Water Distribution.

3. Rehabilitation and Replacement (Above Ground).

4. Rehabilitation and Replacement (Below Ground).

Table 4 CIP Phasing Implementation Risks, Pros, and Cons Scenario 1 – Risks, Pros, Cons Scenario 2 - Risks, Pros, Cons Scenario 3 - Risks, Pros, Cons Pros:
 Program and project load can be
handled by existing public works
structure
 Only partial deferment of Priority A
R&R projects

Pros:
 All priority A projects completed in the
Near-Term
 No Priority A R&R projects deferred
beyond 2029
Pros:
 Slowest implementation rate
makes meeting CIP
schedule more obtainable
 Potentially lower near-term
rate impacts
Cons:
 While some Priority A projects are
completed in the Near-term, some
high risk R&R projects are deferred
for over 5-years.
 Risk of deferred could increase
annual O&M costs for identified
R&R projects

Cons:
 Near Term Priority A project schedule will
require outside engineering assistance
(i.e., program manager) to complete all
project by 2029
 Public impacts due to multiple projects
being completed in Near-term
 Highest Near-term rate impacts
 Largest Financing Requirement
Cons:
 Potential deferment of
Priority A R&R projects for
up to 10-years
 Increased O&M cost due to
deferment of Priority A R&R
projects
 Highest rate of spending
over years 6-20 (2029 to
2044)

Risk:
 Facility failure due to deferment
 Increased O&M costs
Risk:
 Not meeting CIP schedules after high
rates increases creates public and
institutional challenges
Risks:
 Facility failure due to
deferment
 Increased O&M costs
