On May 2, 2006, the State Water Resources Control Board issued Order 2006-0003, Statewide General Waste Discharge Requirements (WDR) for sanitary sewer systems. This Order was issued to ensure consistent and comprehensive regulation of publicly-owned sanitary sewer systems throughout the State, and to quantify and reduce Sanitary Sewer Overflows (SSOs).

The WDR requires all wastewater collection agencies with sanitary sewer systems more than one mile in length to electronically report SSOs to the State Water Resources Control Board and to develop and implement a Sewer System Management Plan (SSMP). The SSMP is a written document that details how the agency’s sanitary sewer system is operated, maintained, evaluated, and funded.

When complete, the SSMP will include eleven elements:

  • Goal
  • Organization
  • Legal Authority
  • Operation and Maintenance Program
  • Design and Construction Standards
  • Overflow Emergency Response Plan
  • Fats, Oils, and Grease Control Program
  • System Evaluation and Capacity Assurance Plan
  • Monitoring, Measurement, and Program Modifications
  • SSMP Audits
  • Communication Program

The City's SSMP was adopted by the City Council in October 2009 and was updated in January 2015.
