What's New at Central San




70 Years and Beyond - Central San's Comprehensive Wastewater Master Plan (CWMP)

Since 1946 ince 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.

In order to plan for the future and lay out a 20-year vision for the replacements and upgrades, Central San commissioned a Comprehensive Wastewater Master Plan (CWMP). The CWMP encompasses a $1.8 billion (2016 dollars), two-decade-long capital improvement program (CIP) for the collection system and treatment plant, with $873 million of capital improvements within the first ten years. The recommended projects from the CWMP were separated into four programs including the recycled water system, treatment plant, collection system and general improvements. It also identifies potentially needed improvements for anticipated  or pending regulations, but funding for these is not included in the CIP.
