The Central Contra Costa Sanitary District (Central San) has been protecting public health and the environment by collecting and cleaning wastewater from the residents and businesses of central Contra Costa County since 1946. Whatever goes down their toilets and drains travels through our vast 1,500 miles of sewer system to our award winning treatment plant in Martinez, where we clean over 13 billion gallons of wastewater each year. Most of that water is safely cleaned and released into Suisun Bay. An additional 2 million gallons each day of recycled water is produced for landscape irrigation and industrial uses. Central San also operates a one of the most highly successful Household Hazardous Waste Collection Facilities in the nation and sponsors 13 pharmaceutical collection bins. Please visit our website, CentralSan.org, for more information.
