To provide a consistent, statewide regulatory approach to address the issue of sanitary sewer overflow (SSO), the State Water Resources Control Board (State Water Board) adopted Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems, Water Quality Order No. 2006-0003 (Sanitary Sewer Systems WDR) on May 2, 2006. The Sanitary Sewer Systems WDR requires public agencies that own or operate sanitary sewer systems to develop and implement sewer system management plans and report all SSOs to the State Water Board’s online SSO database.
The State Water Resources Control Board requires all agencies that own or operate a wastewater collection system, to develop and implement a Sewer System Management Plan (SSMP) that documents how the City manages its wastewater collection system. On December 6, 2022, the State Water Resources Control Board adopted the reissued Statewide General Waste Discharge Requirements and the Monitoring and Reporting Program (WDR) by issuing Order No. 2022-0103-DWQ.
This WDR requires owners and operators of publicly owned collection sewer systems to develop and present a Sanitary Sewer Management Plan (SSMP) to their governing body for approval. The WDR requires that the SSMP be updated every five years and must include any significant program changes. The City of San Dimas is required to comply with this order as it owns approximately 103 miles of sewer that are primarily maintained by the Los Angeles County Sewer Maintenance District.
The City’s Sewer System Management Plan (SSMP) can be viewed through the link below. Hard copies and copies of the attachments may be considered upon request at City Hall.
If you have any questions or concerns regarding the sewer, please contact the City of San Dimas Public Works Department at 909.394.6240. For emergencies, contact the Los Angeles County Consolidated Sewer Maintenance District directly at 1.800.675-HELP(4357).
