Welcome to the Upper Blackstone Water Pollution Abatement District. We are one of New England’s largest clean water treatment plants serving roughly 250,000 people in the greater Worcester area and managing biosolids for an additional 14 communities.

District member communities include the City of Worcester and the Towns of Auburn, Holden, Millbury, Rutland, West Boylston, and the Cherry Valley Sewer District (CVSD), a portion of the Town of Leicester.

The District serves our customers by providing a high level of wastwater treatment to effluent discharged near the headwaters of the Blackstone River in Millbury, Massachusetts.

The Blackstone River originates at the confluence of Middle River and Mill Brook in Worcester and flows southeast for 46 miles into Rhode Island where it joins the Seekonk and Providence Rivers, subsequently discharging to Narragansett Bay. The District’s stringent National Pollutant Discharge Elimination System (NPDES) permit limits are based on the water quality standards of both the River and Bay. To meet these standards, the District operates a biological nutrient removal (BNR) treatment process to reduce conventional pollutants as well as nitrogen, phosphorus, and metals.
