The Marysville Wastewater Treatment Facility (WWTF) is a municipal treatment plant located in Marysville, California, serving a population of about 13,627. Situated in Yuba County, the plant is part of the region's infrastructure for managing domestic wastewater from the city and surrounding areas. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the U.S. Clean Water Act, enforced through National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. These permits set effluent limits to protect water quality in receiving water bodies. The plant's treated effluent likely discharges into the Yuba River, a tributary of the Feather River, which flows into the Sacramento River and ultimately the Sacramento-San Joaquin Delta and San Francisco Bay. This watershed supports diverse aquatic life and is critical for regional water supply and ecosystem health.

Environmental context

This estuarine environment supports a variety of fish species, including salmon and steelhead, and is an important migratory corridor. The region's Mediterranean climate with seasonal rainfall influences flow patterns and pollutant dilution.
