Sewer System Management Truck

The State Water Resources Control Board’s adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2022-0103-DWQ on December 6, 2022. This General Order serves as statewide discharge requirements and supersedes the previous Order 2006-0003-DWQ and amendments thereafter.   The General Order regulates sanitary sewer systems designed to convey sewage. For the purposes of the Order, a sanitary sewer system includes but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures, and other pertinent infrastructure upstream of a wastewater treatment plant headworks. All sections and attachments of this General Order are enforceable by the State Water Board and the Regional Water Quality Control Board.   To comply with the terms of the General Order, owners of a sanitary sewer system greater than one mile in length must implement a Sewer System Management Plan (SSMP). The SSMP is intended to reduce the number, frequency, and severity of sanitary sewer spills, and the General Order requires that the SSMP be audited every three years and updated every six years.   The Board of Directors initially adopted and certified IEUA’s first SSMP in 2009. Under the new Order, the audit was completed in November 2024, and the SSMP update is due by May 2, 2025. IEUA’s staff, with support from a consultant, conducted the audit and the SSMP update.
