Project Overview
San Francisco’s 884,000 residents rely on the Southeast Treatment Plant (SEP) to process about 80 percent of their wastewater—sanitary sewage and stormwater runoff at a rate of 57 million gallons per day (MGD) with peak flows of 250 MGD during large storm events.
51¹ú²úÊÓƵ and JV partner Walsh Construction are in the process of replacing the existing headworks with a new all-weather 250 MGD facility, which will include cutting-edge Hydra-Cell® technology. The upgrades will increase efficiency and protect downstream equipment, achieve the city’s Level of Service goals and minimize odors.
Since the SEP sits in the middle of a mixed industrial, commercial and residential area, with homes just across the street, these upgrades should be a welcome change for the community once they are finished. This work is part of the city’s larger Sewer System Improvement Program (SSIP), a series of capital improvement projects focused on upgrading and modernizing San Francisco’s combined sewer system.
