Cambria CSD provides wastewater treatment and disposal services to approximately six-thousand (6,000) residents in the Cambria area. Cambria CSD operates a one-million (1,000,000) gallon per day extended aeration activated sludge secondary WWTP in Cambria. The original WWTP was constructed in 1970. In 1995, a major upgrade was completed to improve the WWTP’s ability to reliably meet the discharge requirements of the Regional Water Quality Control Board (RWQCB).

The RWQCB, Central Coast Region 3, oversees the sanitary sewer system requirements as defined in State Water Quality Order NO. 2006-003 DWQ. The State Water Resources Control Board has requested the RWQCB administer compliance of its newly defined State Water Quality Order. During May 2012, the CCSD Board of Directors adopted the Sanitary Sewer Management Program. Since then, the Water Board amended the monitoring and reporting program (MRP) with the issuance of Order No. 2013-0058-EXEC. This more recent MRP modified the title of the program to "Sewer System Management Plan" (SSMP). At the regular Board of Directors meeting held on May 24, 2018, the CCSD's SSMP was re-certified to maintain compliance with the State Water Quality Order.
