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 to comply with the new requirements adopted May 2, 2006, by the State Water Resources Control Board (Water Board) under Water Quality Order Number 2006-003, State General Waste Discharge Requirements (WDR) for Sanitary Sewer Systems.
