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

The Water Pollution Control Plant (WPCP) gas utilization system is designed to allow for optimum use of gas produced in the anaerobic digesters and of the gas recovered from the former Sunnyvale landfill. The gases are beneficially used in the main engines (plant influent pumps) and the Power Generation Facility (PGF). Natural gas is used as a supplemental fuel when necessary. The gas utilization system controls, meters and distributes the gases to the intended points of use. When necessary, excess digester gas can be directed to the waste gas burners and excess landfill gas can be directed to the landfill gas flare which consists of two flares. One of the landfill gas flares is automated which lights when pressure in the system exceeds the set point to relieve excess gas pressure. The other is manually operated. The waste gas burner system has had several revisions since it was first installed in 1952 including the installation of a newer flare in 1989. This project will include design and construction of upgrades necessary to support air permitting requirements and higher loads concurrent with Projects 833350 - SCWP Digester No. 5 and 833360 FOG/Food Waste Facility. This project is in included in the City of Sunnyvale FY 2022/23 Adopted Budget . As of September 22, 2022, further details regarding design and construction have not been identified. *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.
