Hamilton City WWTF - Secondary Wastewater Treatment in Merced County, California

Hamilton City WWTF is a municipal wastewater treatment facility located in Merced County, California, United States. The plant serves a small population of 1,824 residents, providing secondary treatment to meet state and federal water quality standards. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 908.50 volume units and a discharge volume of 908.50 volume units, the facility operates at full capacity. As a small-scale plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways within the San Joaquin River basin, which ultimately drains to the Sacramento-San Joaquin Delta and San Francisco Bay. The plant plays a role in protecting downstream aquatic ecosystems and supporting water quality in the region's agricultural and natural landscapes.

The plant discharges into the San Joaquin River watershed, which flows through California's Central Valley to the Sacramento-San Joaquin Delta and San Francisco Bay. This estuarine environment supports diverse aquatic life, including salmon and migratory birds. The region's agricultural runoff and urban discharges require careful management to maintain water quality and ecosystem health.
