CAROLLO ENGINEERS, INC. 3RD AMENDMENT (#2022494)

Page 2 of 3 BACKGROUND The City distributes approximately 4,500 million gallons of treated water per year to 22,000 customers. The City has two sources of water supply: (1) treated surface water and groundwater purchased from Zone 7 Water Agency and (2) groundwater from three City owned and operated wells with a total pumping allotment of 1,140 million gallons per year. The City’s distribution system consists of 20 storage tanks, 14 pump stations, and over 300 miles of piping. The annual operating budget for the water system program is approximately $29 million (capital improvement plan expenditures not included). The City’s water system program requires management of various elements including administration, planning, operations and maintenance, capital improvements, resources, and financing. Attachment 1 provides an illustration of these program elements. DISCUSSION To ensure the effective management of its water system, the City is preparing a WSMP that will be a living document, reviewed every three years to evaluate its effectiveness and comprehensively updated every six years. Initial development will occur in three phases: • Phase 1 – High Level Assessment of City’s Water System Program: This phase will include utilizing the United States Environmental Protection Agency’s Effective Utility Management guidance document to evaluate the City’s existing water system program practices and make recommendations for improvements. • Phase 2 – Develop Work Plan: This phase will develop a work plan to prioritize and implement improvements based on the outcome of Phase 1. The work plan will include a schedule that spans a minimum of six years so that it covers the time period of the initial WSMP through the first comprehensive WSMP Update. The work plan will prioritize activities to occur as part of the initial WSMP, activities to occur as part of future WSMP updates, and activities that although guided by the WSMP will occur through separate planning efforts (e.g., urban water management plans, water rate studies, water connection fee studies, etc.). The work plan will recommend the timing of these activities for proper integration. • Phase 3 – Prepare Initial WSMP: The City will develop the initial WSMP in accordance with the work plan from Phase 2. The WSMP will be organized by the program elements shown in Attachment 1. Anticipated tasks to be included in the initial WSMP include, but are not limited to: o Establish goals, key performance indicators, and policies to guide the water system. o Review/summarize existing planning efforts (e.g., urban water management plans, risk and resiliency assessments, water distribution capacity evaluations, etc.), identify planning gaps, and perform high priority planning tasks (e.g., establish an asset renewal and replacement program, perform a regulatory review, etc.). o Review/summarize existing operation and maintenance practices, identify deficiencies, and perform high priority tasks (e.g., establish a standard operating procedures program and competency-based training program). o Recommend a prioritized list of actions, programs, and capital improvement projects to be implemented to improve management of the water system.
