Sewer System Management Plan (SSMP)

The State of California requires publicly owned sanitary sewer systems to develop and implement a Sewer System Management Plan (SSMP), including measures to control and mitigate sewer spills. The City maintains and periodically audits and updates its SSMP pursuant to the State requirements. You may access the City’s current SSMP by clicking on the link below.

Pursuant to the State Water Board’s General Waste Discharge Requirements (WDRs), the City audits its SSMP once every two years to ensure continued compliance with the WDRs and effectiveness in addressing sewer spills. The City’s current SSMP was updated in January 2019 upon completion of a biennial audit. The audit team reported that the City’s SSMP is effective in controlling sewer spills and in providing mitigation measures when spills occur. The audit report is available via the following link.
