Converting From An Individual Private Septic System To CCCSD Public Sewer Service

Central Contra Costa Sanitary District (CCCSD) is an independent special district that collects and treats wastewater for ten cities in central Contra Costa County.  Our mission is to protect public health and the environment.  One way to accomplish this mission is to assist property owners who choose to or need to convert from individual private septic systems to CCCSD public sewer service.  The following are questions about this subject frequently asked of CCCSD staff.  For additional information about CCCSD requirements and procedures, call (925) 229-7371.

The Contra Costa Environmental Health Division (CCEH), not CCCSD, is the public agency responsible for regulating septic systems throughout Contra Costa County. Information about CCEH’s requirements regarding maintenance, expansion, enhancement, replacement or abandonment of septic systems is available at http://www.cchealth.org/groups/eh or by calling (925) 692-2536.
