MW-t 1tIMli L Capital Projects Division Manager 7 { U96- t.. -.- - Ts :11111111111m,ft Since 1946, Central Contra Costa Sanitary District (Central San) has provided safe and reliable wastewater collection and treatment for residents in central Contra Costa County. Today we serve over 481,600 residents and 3,000 businesses in 147 square miles. Our services include supplying recycled water for parks and golf courses, providing both commercial and residential recycled water pickup programs, operating a household hazardous waste collection facility and running a sophisticated water quality laboratory. Our core mission is to protect public health and the environment, and our customers can count on us for vital services 24 hours a day, every day. Central San's infrastructure includes a 1,540-mile collection system (including 18 pumping stations) and a wastewater treatment plant that have been well maintained, but due to their advanced ages, now require renovation and upgrades. Already, the equipment at the plant and in the system have been extended well beyond their typical useful life due to responsible and robust maintenance practices. Some of the collection system facilities are over 100 years old, and many are over 50 years. The treatment plant facilities were primarily constructed in the 1970s and some are now at the point where maintenance alone cannot maintain reliable performance. These recommended extensive renovation and improvement projects will provide for continued reliable operation. Central San funds an extensive Capital Improvement Program (CIP) designed to prepare, maintain, optimize, and enhance Central San's assets-, meet regulatory requirements, accommodate the community needs-, and protect public health and the environment. Capital improvements are construction or renovation activities that add value to Central San's fixed assets (pipelines, buildings, facilities, and equipment) or significantly extend their useful life. This report summarizes the CIP's progress and major highlights or accomplishments in Fiscal Year (FY) 2024-25, Quarter 2 (October to December 2024).

For major infrastructure projects, engineering firms with specialty or multi -discipline professionals including sub -consultants are commonly hired. Central San then solicits public bids for the project and procures a general contractor to construct the project based on the contract documents. Alternatively, Central San is working on a second method for project delivery that consists of a Design -Build approach. This delivery method contracted with a single design -build firm in which the design, cost estimating, construction is package under a final guaranteed maximum price (GMP) contract. This approach has two phases (final design and construction) for consideration and approval. Regardless of project delivery method, every project follows a consistent process of consecutive delivery stages as presented in the model below: Project Highlights - Collection System/Pumping Station Pump Station Upgrade - Phase 2A Protect Description The project involves replacing corroded steel dry pits with new wet wells at Fairview and Maltby Pumping Stations, backup generators, instrumentation, pumps, valves, gates, all piping, and concrete.

It includes rehabilitating infrastructure to ensure reliable process systems, meeting or exceeding employee safety standards, and responding to regulatory requirements for pending air emissions regulations. Additionally, the program emphasizes increasing sustainability efforts and implementing energy -related projects to support long-term environmental and operational goals. There are 33 active projects in the Treatment Plant Program. All are multi -year efforts that range from the project planning stage to nearing construction completion or yearly budgets for equipment or other needed functions at Central San. In all cases, performance can be tracked at the yearly spending level. In FY 2024-25, the emphasis is on 6 large projects which together account for $47.5 million or 78% of the total Treatment Plant Budget for the year. Each major project budget is shown below.

Program Summary - Recycled Water The Recycled Water (RW) Program this fiscal year focuses on finalizing the construction and permitting of the Filter & Clearwell Improvements — Phase 1A project to upgrade recycled water treatment and storage facilities. Additionally, Phase 1 B will complete the design for electrical replacements and filter upgrades at the Filter Plant. Efforts will continue to attract new customers in Zone 1, pursue federal and state funding for recycled water projects, and collaborate with regional water supply agencies on alternatives like the Water Exchange Project with Contra Costa Water District and discussions with other districts including EBMUD and SFPUC. There are 5 active projects in the Recycled Water Program. All are multi -year efforts that range from the project planning stage to nearing construction completion or yearly budgets for equipment or other needed functions at Central San.
