Delta Diablo Information

Delta Diablo is an innovative and award winning wastewater resource recovery agency providing wastewater, recycled water, street sweeping, and household hazardous waste services to an estimated 200,000 residents and businesses in communities of Antioch, Bay Point, and Pittsburg. The District is located in the heart of the Northern California Delta region, 50 miles east of San Francisco and has a service area encompassing 54 square miles with over 70 miles of underground pipeline systems. In 2014, the District treated 4.6 billion gallons of wastewater and is permitted for an average dry weather flow of 19.5 million gallons per day. Delta Diablo also operates a recycled water treatment and distribution system that supplies up to 12 million gallons of tertiary-treated water daily. Since 2001, this recycled water system has been instrumental in increasing water supply reliability by offsetting water demands from the Sacramento/San Joaquin Delta. The recycled water is used for cooling by 2 power generation plants and landscape irrigation for 12 municipal parks, 2 golf courses and 2 schools in the service area. The recycled water facility has generated over 26 billion gallons of recycled water to date. The District also oversees street sweeping services in its service area and operates a household hazardous waste collection facility for East Contra Costa County. The District’s employees are committed to the vision of making the Agency a national leader in “waste” water resource recovery. Delta Diablo is developing and expanding regional partnerships that leverage environmental stewardship opportunities, further protect the public health, and explore new ways to recover resources by the taking the “waste” out of wastewater. Delta Diablo is governed by a three-member Board of Directors, which includes the Mayors for the Cities of Antioch and Pittsburg, and a member of the Contra Costa County Board of Supervisors that represents the Bay Point community.
