This project involves the replacement of the sewage‑ejector system for the Creative Arts Extension building at the San Francisco Community College campus. The work includes demolition of existing concrete and equipment, installation of two new submersible grinder pumps, associated piping, control panels, electrical upgrades, and site‑wide commissioning.
