Orange County Sanitation District

The Orange County Sanitation District is a public agency responsible for safely collecting and treating wastewater for 2.6 million people. OC San beneficially reuses and recycles the treated wastewater and other resources resulting from the treatment process. It is a special district established by the California State legislature and governed by a 25-member board of directors. The directors are comprised of elected representatives for each of the sewer agencies or cities within OC San's 479-square-mile service area. For more information, visit our website at www.ocsan.gov.
