Westborough Wastewater System - Municipal Treatment in Westborough, Massachusetts

Westborough Wastewater System is a municipal treatment facility located at 225 Turnpike Road in Westborough, Massachusetts, serving a population of about 38,379. The plant is situated in Worcester County, an inland area with no coastal proximity, and treats wastewater from the local community. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the US Clean Water Act, which requires removal of at least 85% of biochemical oxygen demand and suspended solids. The facility operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Massachusetts Department of Environmental Protection, ensuring compliance with federal and state water quality regulations. The treated effluent is discharged into a local water body, likely a tributary of the Assabet River or the Sudbury River, both part of the larger Concord River watershed. This region supports diverse aquatic life and is important for recreational activities. The plant's operations help protect downstream ecosystems, including the Sudbury-Assabet-Concord River system, which ultimately drains into the Merrimack River and the Atlantic Ocean.

The plant discharges into a local water body within the Concord River watershed, which flows into the Merrimack River and eventually the Atlantic Ocean. The watershed supports diverse aquatic species and is an important migratory corridor for fish. Protecting water quality here helps maintain ecological balance in downstream rivers and estuaries.
