CITY COUNCIL REGULAR MEETING AGENDA PACKET (2)

Page 2 of 5 Resources Control Board's Division of Drinking Water (DDW). The City serves potable water to approximately 22,000 customers through a water distribution system comprising approximately 330 miles of piping, 19 storage tanks, and 14 booster stations. The City’s water supply comes from wholesale purchases from the Zone 7 Water Agency (Zone 7) and a groundwater production quota (GPQ) of 3,500 ac/year (representing approximately 20 percent of the City’s total water supply needs). The City is currently not utilizing its GPQ because all its groundwater wells contain measurable PFAS concentrations and are not equipped with treatment technology for PFAS removal treatment. Instead, the City is purchasing 100 percent of its water from Zone 7 at wholesale cost because Zone 7 has highly effective PFAS treatment for the drinking water it supplies. The City has developed the attached Water System Management Plan (WSMP), provided as Attachment 1, to serve as a foundational planning document for the management of its water system. This initial WSMP's focus is to develop a near-, mid-, and long-term Capital Improvement Program (CIP) and recommend improvements to the operation and maintenance (O&M) program to determine funding needs that will ensure water system sustainability. The WSMP will be reviewed on a 2-year cycle to evaluate implementation progress and will be updated on a 6-year cycle to reflect any changes in key factors and needs. The next WSMP update will include evaluating the water system using the US Environmental Protection Agency’s (EPA) Effective Utility Management (EUM) framework. The EUM focuses on attributes such as product quality, customer satisfaction, stakeholder understanding and support, financial viability, operational optimization, employee leadership and development, and enterprise resilience. DISCUSSION Carollo Engineers was contracted by the City to prepare the WSMP. Carollo conducted and reviewed several technical evaluations on topics including water supply, water distribution system capacity, water quality, water conservation, condition of facilities, overall system risk and resilience, energy and emergency power, supervisory control and data acquisition (SCADA), and O&M best practices. These efforts were used to inform the CIP and O&M program recommendations discussed in this section. Capital Improvement Plan (CIP) The CIP is a list of recommended projects that fall within the major categories listed below: • Water Supply • Water Distribution • Rehabilitation and Replacement (R&R) • Other (includes other projects such as SCADA, power, etc.). Each recommended project has been prioritized based on the following system: • Priority Level A- Projects required for health and safety; required by law, regulation, or contract; are currently under construction; and/or are funded by applicants or outside funding sources. o These projects include emergency backup generator replacements, near- and long-term improvements for water supply, projects that address pipeline deficiencies or improve fire system flow, and tank and booster station Page 422 of 658
