Sewer System Management Plan (SSMP)

On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Order Number 2006-0003-DWQ, Waste Discharge Requirements (WDRs), which requires all federal and state agencies, municipalities, counties, districts, and other public entities that own or operate a wastewater collection system greater than one (1) mile in length to develop and implement a system specific Sewer System Management Plan (SSMP). The SSMP must document how an agency manages its wastewater collection system.

This SSMP provides a summary of the action plan implemented by the County to comply with the requirements imposed by the WDRs and other governing agencies. It includes a description of the activities and procedures that District staff follow to efficiently manage, operate, and maintain the sanitary sewer system and to minimize the risk of sanitary sewer overflows (SSOs).

Sewer System Management Plan

The goals of the SSMP are to:

  • Minimize the frequency and impact of sanitary sewer overflows (SSOs)
  • Effectively and efficiently mitigate the impacts of SSOs should they occur
  • Provide adequate sewer capacity to convey peak flows
  • Maintain and improve the condition of the collection system infrastructure to provide continual reliable service
  • Engage and educate the public regarding programs and issues related to the wastewater collection system
