Renovation of a water / sewer project in Petaluma, California. Conceptual plans call for the renovation of a water / sewer project.

The existing force main is a crucial pressurized conduit that channels wastewater from the Primary Influent Pump Station (PIPS) to the Ellis Creek Water Treatment Facility. Recognizing the importance of a reliable wastewater system, the City is currently advancing two key projects: the installation of a new PIPS Parallel Force Main (C66502023) and the PIPS Upgrade and Pump Replacement (C66501930). Upon the successful integration and operation of the new force main and pump station upgrades, the City will rehabilitate the existing force main. This proactive approach establishes a backup system, enhancing the City’s wastewater system's redundancy and overall resilience. Without such a contingency plan, any failure in the force main could jeopardize the City's ability to effectively transport wastewater to the treatment facility. This project will include a comprehensive analysis to determine the most suitable rehabilitation method, followed by the commencement of construction once the new force main is fully operational. As of Sept 3, 2025, this project is included in the City's 2026-2030 Capital Improvement Program (CIP) *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
