Biggs Wastewater Treatment Facility (WWTF) is a municipal wastewater treatment plant located in Biggs, Butte County, California. It serves a population of approximately 1,793 residents, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater before discharge. With a designed capacity of 1,324.89 thousand cubic meters per year and an actual discharge volume of 681.37 thousand cubic meters, the facility operates well within its capacity. As a U.S. plant, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the California State Water Resources Control Board, ensuring compliance with federal and state water quality standards. The treated effluent from Biggs WWTF is discharged into local waterways that ultimately drain into the Sacramento River system, a major tributary of the San Francisco Bay and Delta. This watershed supports diverse aquatic life and provides critical habitat for migratory fish species, including salmon and steelhead. The plant's secondary treatment helps protect downstream water quality in this ecologically significant region.

Biggs WWTF discharges into the Sacramento River watershed, which flows through California's Central Valley and empties into the San Francisco Bay and Delta. This estuarine environment supports a rich diversity of fish, birds, and other wildlife, including several threatened and endangered species. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this ecologically sensitive region.
