Southeast WPCP - San Francisco, California Wastewater Treatment Plant

Southeast WPCP is a major wastewater treatment facility located in San Francisco, California, serving a population of approximately 949,125. As a large-scale municipal plant, it plays a critical role in managing the city's wastewater within the densely populated Bay Area. The plant's designed capacity is 1. Under the US Clean Water Act, facilities of this scale are required to meet stringent National Pollutant Discharge Elimination System (NPDES) permit conditions, which typically mandate secondary treatment and may include additional nutrient removal requirements for sensitive water bodies. Treated effluent from Southeast WPCP is discharged into the San Francisco Bay, a major estuary that connects to the Pacific Ocean. The Bay supports diverse aquatic life, including fish, birds, and marine mammals, and is an important ecological and economic resource for the region. The plant's operations are essential for protecting water quality in this sensitive coastal environment.

Southeast WPCP discharges into the San Francisco Bay, which flows through the Golden Gate into the Pacific Ocean. The Bay is a large, ecologically productive estuary that supports migratory birds, fish species, and marine habitats. Protecting water quality in this watershed is critical for maintaining biodiversity and supporting recreational and commercial activities.
