CERES WWTP - Waterford, California Wastewater Treatment Plant

CERES WWTP is a municipal wastewater treatment facility located in Waterford, California, within Stanislaus County. Serving a population of around 37,000, the plant is part of the region's wastewater infrastructure, handling domestic and commercial flows from the community. As a US-based facility, CERES WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. For a plant of this scale, secondary treatment is typically required, with potential additional nutrient removal if discharging to sensitive waters. The plant's treated effluent is discharged to local waterways that ultimately drain into the San Joaquin River system, which flows through the Central Valley to the Sacramento-San Joaquin Delta and San Francisco Bay. This watershed supports diverse aquatic life and is critical for regional water supply and agriculture.

CERES WWTP discharges into the San Joaquin River basin, which flows through California's Central Valley to the Sacramento-San Joaquin Delta and San Francisco Bay. The downstream environment supports important fish species and migratory birds, and the river system is heavily managed for water quality and supply. Nutrient loading from wastewater can impact algal growth and oxygen levels in the Delta.
