It serves a population of approximately 2,615 residents within the town, operating as a secondary treatment facility. The plant is situated inland, away from coastal areas, and its operations are part of the local infrastructure managed by the town. As a secondary treatment plant, the Sunderland Collection System employs biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 1,892.70 megaliters and currently discharges 794.94 megaliters annually, indicating it operates below its full capacity. Under the U.S. Clean Water Act, such facilities are required to meet National Pollutant Discharge Elimination System (NPDES) permit standards, which are enforced by the Massachusetts Department of Environmental Protection. The treated effluent from the plant is discharged into a local water body, likely a river or stream within the Connecticut River watershed. The Connecticut River flows southward through Massachusetts and Connecticut, eventually emptying into Long Island Sound. This watershed supports diverse aquatic life and provides habitat for migratory fish species, making proper wastewater treatment essential for maintaining water quality in the region.
