Central Contra Costa Sanitary District is a regional public utility that collects and treats wastewater in central Contra Costa County, California. Serving nearly 500,000 residents and more than 15,000 businesses, it operates a 1,500-mile sewer network directing flow to its Martinez treatment facility, where about 13 billion gallons are processed each year. In addition to treatment, the district runs a Household Hazardous Waste Collection Facility and provides recycled water for landscape irrigation and industrial use. It also pursues pollution prevention through education, outreach, and inspection programs to protect public health and the environment.

Founded in 1946, Central San is based in Martinez, California, and functions within the utilities sector as a wastewater and environmental services provider. A recent development is a partnership with Aquasight to pilot a digital twin for wastewater treatment intended to improve process efficiency, reduce operating costs, and extend asset life.
