The State Water Resources Control Board (SWRCB) recently passed Order Number 2022-0103-DWQ on December 6, 2022. This statewide Waste Discharge Requirements (WDRs) general order for Sanitary Sewer Systems applies to all federal and state agencies, municipalities, counties, districts, and other public entities responsible for a wastewater collection system longer than one mile. The order mandates that agencies must create a Sewer System Management Plan (SSMP) specific to their system to efficiently manage their wastewater collection system.

The City of Pomona has created an SSMP that fully complies with the WDR requirements. The document outlines the City's detailed plans and programs for the operation, maintenance, and management of its wastewater collection system.

To ensure ongoing compliance and improvement, the City updates its SSMP every five years. The 2018 SSMP is a five-year update to the 2013 SSMP, and the City will conduct audits every three years according to the new order, with the next audit scheduled for May 2024. Additionally, the City will update its SSMP in May 2025, as required by the new order.
