VSFCD WWTF - Vallejo, California Wastewater Treatment Plant

VSFCD WWTF is a municipal wastewater treatment facility located in Vallejo, Solano County, California. Serving a population of around 115,942, the plant is a key component of the region's wastewater infrastructure, handling domestic and industrial flows from the Vallejo area. Under the US Clean Water Act, facilities of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. The plant's designed capacity is 1.00 million gallons per day, reflecting its role in managing local wastewater volumes. The plant's treated effluent ultimately discharges into the San Francisco Bay estuary, a critical ecological system that supports diverse aquatic life and migratory bird populations. The bay connects to the Pacific Ocean via the Golden Gate, making the plant's operations important for both local water quality and downstream marine environments.

The plant discharges into the San Francisco Bay, which is part of the larger San Francisco Bay-Delta estuary. This watershed drains much of California's Central Valley and supports a rich ecosystem including salmon, steelhead, and migratory waterfowl. The bay's connection to the Pacific Ocean makes nutrient and pollutant management crucial for marine health.
