Sewer System Management

Our District's sewer collections system is operated in accordance to our Sewer System Management Plan (SSMP), as required by the State Water Resources Control Board's Statewide General Waste Discharge Requirements for sanitary sewer systems.

Our SSMP was originally adopted in March 2011.  It is audited and reviewed every two years to ensure that we continue to improve in our efforts to avoid sanitary sewer overflows of any kind.  Our current SSMP was updated and adopted in November 2019.  Click the link below for a full copy and to learn about how we manage our sewer system operations.
