Wallingford WPCF is an advanced wastewater treatment facility located at 5 Pent Road in Wallingford, Connecticut. The plant serves a population of about 28,750 residents within the South Central Connecticut Planning Region, providing essential wastewater treatment for the community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 1.00 million gallons per day, the facility is sized to handle the wastewater generated by the local population. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permit requirements, which set effluent limits to protect water quality. The treated effluent from Wallingford WPCF is discharged into local waterways that ultimately drain to Long Island Sound. The Quinnipiac River watershed, which flows through the area, is an important ecological corridor supporting diverse aquatic life. The plant's advanced treatment helps reduce nutrient loading, protecting the sensitive estuarine environment of Long Island Sound from eutrophication.

The plant discharges into the Quinnipiac River watershed, which flows southward into Long Island Sound, a large estuary that supports diverse marine life including shellfish, finfish, and migratory birds. The Sound is ecologically sensitive to nutrient pollution, making advanced treatment crucial for maintaining water quality and preventing algal blooms.
