Plainfield Village Water Pollution Control Facility - Connecticut Wastewater Treatment

Plainfield Village Water Pollution Control Facility (WPCF) is a municipal wastewater treatment plant located in Plainfield, Connecticut, serving a population of approximately 3,641. The facility is situated at 28 Black Hill Road in Central Village, within the Northeastern Connecticut Planning Region. As a small-scale treatment plant, it plays a key role in managing wastewater for this rural community. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal facilities. The designed capacity of 1.00 million gallons per day suggests the plant is sized appropriately for its service population. Compliance with National Pollutant Discharge Elimination System (NPDES) permits is standard for such facilities, ensuring treated effluent meets federal and state water quality standards. The plant's treated effluent is discharged into local streams that flow into the Quinebaug River, a tributary of the Thames River, which ultimately drains into Long Island Sound. This watershed supports diverse aquatic life and provides recreational opportunities. The facility's operations help protect downstream water quality in this ecologically sensitive region.

The plant discharges into the Quinebaug River watershed, part of the larger Thames River basin that flows into Long Island Sound. This coastal estuary supports critical habitats for fish, shellfish, and migratory birds. The facility's treatment helps reduce nutrient loading and protect water quality in this ecologically important system.
