CENTRAL SAN January 19, 2021 TO: ENGINEERING AND OPERATIONS COMMITTEE FROM: JEAN-MARC PETIT DIRECTOR OF ENGINEERINGAND TECHNICAL SERVICES REVIEWED BY: ROGER S. BAILEY, GENERAL MANAGER SUBJECT: RECEIVE UPDATE AND OVERVIEW OF THE CAPITAL IMPROVEMENT PROGRAM (CIP) Central San has developed a Ten-Year Capital Improvement Plan (Ten-Year CI P)for capital facilities and financing needs. The Ten-Year CI P covers the period starting July 1, 2020 and ending June 30, 2030. It incorporates the recommendations from the June 2017 Comprehensive Wastewater Master Plan (CWMP), which is updated every year. Specifically, the plan identifies and prioritizes capital projects needed to accomplish Central San's Vision, Mission, Values, and Goals. It also includes planning-level cost estimates for proposed projects and projections for the various sources of revenue needed to meet the cash flow requirements. The principal purpose of the Ten-Year Cl P is to provide the Board of Directors with the information needed to formulate a long-range policy regarding: • Priority and Schedule — Identify, prioritize, and schedule the projects necessary to accomplish Central San's Vision, Mission, Values, and Goals. • Financing — Plan for sufficient financial resources to complete the proposed projects. The CWMP is a critical tool used by staff to implement the following strategies from Central San's Strategic Plan (Fiscal Year 2020-2022): • Achieve 100 percent Compliance in all Regulations by meeting all air, water, land, and other requirements and by striving to minimize sanitary sewer overflows through the implementation of best management practices. • Reduce Reliance on Non-Renewable Energy by using sustainable practices that minimize waste, maximize resources, and improve the community. • Manage Assets Optimally to Prolong Their Useful Life by facilitating long-term capital renewal and replacement and by protecting Central San personnel and assets from threats and emergencies. • Improve and Modernize Operations through Technology and Efficiency Measures by streamlining workflows, leveraging data, and encouraging the review and pilot testing of new technology to optimize the way Central San works. Some of the potential future projects identified in the CWMP are not currently included in the Ten-Year CI P, but are included as projects and clarified during the annual update. These future projects are not included in the Ten-Year CI P and amount to approximately$920 million, of which roughly$510 million may be within the next 20 years. January 19, 2021 EOPS Regular Committee Meeting Agenda Packet- Page 9 of 66 Page 2 of 19 These projects include the following: • Nutrient Removal (Nutrient Watershed Permit): Possibly within 10 years ** • Water Exchange (Refinery Recycled Water) Project- 20 million gallons per day • Advanced Treatment/Contaminants of Emerging Concern Removal ** • Renewable Energy Projects (triggered by increased power demands from nutrient removal) ** • Concord Community Reuse Project Recycled Water Facilities Improvements • Concord Community Reuse Project Collection System Improvements * • Concord Community Reuse Project Recycled Water Distribution System (Central San's current plan is to wholesale recycled water to Contra Costa Water District who will be in charge of the new distribution system, including storage) * * Projects expected to be cost neutral to Central San ** Projects identified but not currently required by regulations This presentation of the CI P provides a general description of the plan. As projects develop and are prioritized, they are grouped into the four programs (Treatment Plant, Collection System, General Improvements, and Recycled Water Program). In total, the estimated costs for all the projects listed in the Ten-Year Cl P is $907.5 million, as shown in the Capital I mprovement Budget (CI B). Strategic Plan re-In GOAL ONE: Customer and Community Strategy 1—Deliver high-quality customer service GOAL TWO: Environmental Stewardship Strategy 1—Achieve 100% compliance in all regulations, Strategy 2—Anticipate and prepare for potential regulatory changes, Strategy 4- Reduce reliance on non-renewable energy GOAL THREE: Fiscal Responsibility Strategy 1—Maintain financial stability and sustainability GOAL FOUR: Workforce Development Strategy 1—Proactively plan for future operational staffing needs, Strategy 4—Meet or exceed industry safety standards GOAL FIVE: Infrastructure Reliability Strategy 1—Manage assets optimally to prolong their useful life, Strategy 2—Execute long-term capital renewal and replacement program GOAL SIX: Innovation and Optimization Strategy 2—Improve and modernize operations through technology and efficiency measures ATTACHMENTS: 1.
