Sewer System Management Plan (SSMP)

The Sanitary Sewer Management Plan, prepared by the Public Works Department, outlines and documents the activities that we utilize to manage our wastewater collection system effectively. Effective management of a collection system includes:

  • Minimizing the number and impact of sanitary sewer overflows (SSOs)
  • Providing adequate sewer capacity to convey peak flows, and
  • Maintaining and improving the condition of the collection system infrastructure to provide reliable service into the future.
The report was prepared by in compliance with requirements of the San Francisco Bay Regional Water Quality Control Board and State Water Resources Control Board pursuant to Section 13267 of the California Water Code. The report is intended to meet the requirements of the Statewide General Waste Discharge Requirements, amended by Order No. 2013-0058, Amended Monitoring and Reporting Program.
