Somerset Water Pollution Control - Wastewater Treatment in Somerset, Massachusetts

Somerset Water Pollution Control is a municipal wastewater treatment facility located in Somerset, Massachusetts, United States. The plant serves a population of approximately 12,902 people, classifying it as a medium-sized agglomeration under US EPA guidelines. It operates under the Clean Water Act, which requires NPDES permits for discharges into surface waters. As a facility serving over 10,000 people, Somerset Water Pollution Control is subject to secondary treatment standards under the Clean Water Act. The plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. Treatment processes typically include primary sedimentation, biological treatment, and disinfection to meet permit limits. The plant discharges treated effluent into local water bodies that ultimately drain to Mount Hope Bay and the Atlantic Ocean. Its proximity to the coast (within 50 km) means that nutrient removal may be important to protect downstream estuarine and marine ecosystems. The facility plays a key role in maintaining water quality in the Taunton River watershed and the broader Narragansett Bay region.

The plant's treated effluent enters local streams that flow into the Taunton River, which empties into Mount Hope Bay, an arm of Narragansett Bay in Rhode Island Sound. This coastal watershed supports diverse aquatic life, including fish, shellfish, and migratory birds. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the bay, making effective treatment critical for ecosystem health.
