Bridgewater Sewer Department - Municipal Wastewater Treatment in Bridgewater, Massachusetts

The Bridgewater Sewer Department is a municipal wastewater treatment facility located at 100 Morris Avenue in Bridgewater, Massachusetts. Serving a population of around 24,596, it operates within the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal plants of this scale. As a medium-sized agglomeration, the facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Massachusetts Department of Environmental Protection. These permits set effluent limits to protect water quality in the receiving water bodies. The plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. The treated effluent is discharged into local waterways that ultimately drain into the Taunton River watershed and then into Mount Hope Bay, part of the Narragansett Bay estuary. This region supports diverse aquatic life and is important for recreational fishing and boating. The plant's operation helps maintain water quality in the sensitive coastal ecosystem of southeastern Massachusetts.

The plant discharges into the Taunton River watershed, which flows into Mount Hope Bay and then into Narragansett Bay, a major estuary on the Atlantic coast. This watershed supports diverse aquatic habitats, including spawning grounds for anadromous fish such as river herring and American shad. The area is ecologically sensitive due to its role in nutrient cycling and as a migratory corridor for fish and birds.
