MILLBRAE MADRONE WWTF - Millbrae, California Wastewater Treatment Plant

MILLBRAE MADRONE WWTF is a municipal wastewater treatment facility located in Millbrae, California, serving a population of about 21,175 residents. The plant is situated in San Mateo County, part of the San Francisco Bay Area, and operates under the regulatory framework of the United States Clean Water Act. As a medium-sized agglomeration, the plant is expected to provide secondary treatment under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. The designed capacity is 1.00 million gallons per day, indicating the plant's scale for handling local wastewater flows. The plant is subject to state and federal discharge standards. The plant's treated effluent likely discharges into the San Francisco Bay or a tributary, given its proximity to the coast. The receiving water body supports diverse aquatic life and is part of a larger estuarine ecosystem that includes migratory fish species and sensitive habitats. The plant plays a key role in protecting local water quality and public health.

The plant is located within 50 km of the Pacific coast, likely discharging into the San Francisco Bay watershed. The bay is a large estuary that supports diverse aquatic life, including fish, birds, and marine mammals. Downstream, the bay connects to the Pacific Ocean via the Golden Gate. The plant's discharge must meet water quality standards to protect this ecologically sensitive environment, which is important for migratory species and regional biodiversity.
