SUMMARY
Digester gas produced at the Hayward Water Resource Recovery Facility (WRRF) fuels the City’s cogeneration engine. The gas also contains hydrogen sulfide and siloxanes from the wastewater, which can severely damage the engine if not removed. The City uses treatment media to remove these compounds, which must be replaced regularly.
On January 24, 2023, City Council awarded a contract to Carbon Supply in an amount not-to-exceed $319,800 for treatment media replacement over four years. Staff is requesting to extend this contract through June 30, 2028 using the 2023 bid pricing and add an additional $137,630.
