Rochdale Water Pollution Control - Oxford, Massachusetts Wastewater Treatment

Rochdale Water Pollution Control is a municipal wastewater treatment facility located in Oxford, Worcester County, Massachusetts. Serving a population of 1,193, the plant provides secondary treatment to domestic wastewater from the Rochdale area. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. With a designed capacity of 681.37 million gallons per year, it treats an equivalent volume, indicating full utilization. The facility is permitted through the EPA's National Pollutant Discharge Elimination System (NPDES), administered by the Massachusetts Department of Environmental Protection. The treated effluent is discharged into a tributary of the French River, which flows into the Quinebaug River and eventually into the Thames River and Long Island Sound. This watershed supports diverse aquatic life and provides recreational opportunities in southern New England.

The plant discharges into a small stream that feeds the French River, a tributary of the Quinebaug River. The Quinebaug joins the Shetucket River to form the Thames River, which empties into Long Island Sound. This watershed is ecologically sensitive, supporting migratory fish species and providing habitat for freshwater mussels and other benthic organisms. The Sound's estuaries are important nursery grounds for marine life.
