CITY COUNCIL REGULAR MEETING AGENDA PACKET (2)

WATER SYSTEM MANAGEMENT PLAN OCTOBER 2024 / CAROLLO CITY OF PLEASANTON WATER SYSTEM MANAGEMENT PLAN 7 SECTION 3 WATER SYSTEM PROGRAM EVALUATIONS OUTSIDE OF THE WSMP There were four additional evaluations conducted outside of the WSMP where the findings were used to inform project recommendations and prioritization. The evaluations included the following: 1. American Water Infrastructure Act (AWIA) of 2018, Risk and Resilience Assessment: West Yost, Final Report April 2021. AWIA Section 2013 requires communities with greater than 3,300 people to develop a Risk and Resilience Assessment (RRA) and an Emergency Response Plan (ERP). The RRA and ERP identifies critical water infrastructure and develops a plan to mitigate potential disruptions to water service in the event of any number of issues. 2. Water Distribution System Capacity Master Plan (WDSCMP): Akel Engineering Group, Inc, Final October 2024. The WDSCMP evaluated the system's ability to provide adequate water supply and pressure for existing and future conditions during peak demand times. The WDSCMP identifies pipeline, storage, and pumping improvements required in the near and long term. 3. Water Supply Alternatives Study (WSAS): Brown and Caldwell, Final Report November 2023. The WSAS evaluated the City's options for long term water supply and developed a recommended approach for moving forward with required supply projects. The supply analysis was to develop a recommended approach to recover use of the City's Groundwater Pumping Quota that has been lost due to PFAS contamination. The report recommended the construction of new supply wells outside of the existing PFAS plume. 4. Pleasanton Generator Report (PGR): TJC and Associates, Final Report November 2023. The purpose of the PGR was to analyze and document the required functionality, design criteria, and execution approach for the integration of backup power systems at the City of Pleasanton Utilities Division potable water pump stations as well as critical sewer and storm stations. The report identified the size and location of new backup power supply through the City for the water, sewer, and storm drainage systems. On October 1, 2024, TJC and Associates provided a presentation of the results of the report to City staff. This presentation had slightly higher cost estimates from that contained in the report and serve as the basis for that included in this WSMP. A copy of the presentation is included in Appendix H. All four of these efforts were used to inform the City's capital and O&M program recommendations. Page 438 of 658
