West Haven Water Pollution Control Facility (WPCF) is a municipal wastewater treatment plant located in West Haven, Connecticut, on the coast of Long Island Sound. Serving a population of approximately 51,654, the facility is a key component of the region's wastewater infrastructure, managing flows from residential and commercial sources in the South Central Connecticut Planning Region. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits and monitoring requirements to protect water quality. Plants of this scale typically employ secondary treatment as a minimum standard under the Clean Water Act. Treated effluent from West Haven WPCF discharges into Long Island Sound, a major estuary that supports diverse marine life, including finfish, shellfish, and migratory birds. The sound is ecologically sensitive due to its role as a nursery habitat and its proximity to urban centers. The plant's location within 50 km of the coast underscores the importance of effective nutrient removal to prevent eutrophication in coastal waters.
