Sewer System Master Plan
The Sewer Master Plan was updated in 2019 to identify necessary capital improvements to meet customer sewer flows over a 30-year planning horizon.
Sewer System Management Plan
The State Water Resources Control Board’s Statewide General Waste Discharge Requirements for Sanitary Sewer Systems Orders require that the City maintain a Sewer System Management Plan (SSMP) which provides a plan and schedule to properly manage, operate, and maintain all parts of the sanitary sewer system. The City’s latest SSMP update was adopted in 2022.
