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

The City installed a micro turbine co-generation system at the Millbrae Water Pollution Control Plant (WPCP) in 2006. The cogeneration system uses biogas generated from the wastewater treatment process to power the micro turbine to produce electricity for use at the WPCP. The co-generation system not only reduces energy costs at the treatment plant but it also reduces greenhouse gas emissions. The co-generation produces over half of the electricity needs for the treatment plant and provides about $250,000 in energy saving annually. Unfortunately, the existing co-generation system has been decommissioned after reaching the end of its useful life. This Project is for the design and construction of a new system. The new system will utilize digester gas produced by anaerobic, produce heat to maintain digesters temperature, produce steam for treatment operation and reduce utility-electricity billing. Rehabilitate digester gas piping; replace engine, replace water heater and refurbish switchgear. As of July 30, 2024, this project is included in the city's 2025-2029 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.
