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.
Sundt 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.
