Prouts Neck W P C F Wastewater Treatment Plant, Scarborough, Maine

Prouts Neck W P C F is a wastewater treatment facility located in Scarborough, Cumberland County, Maine, United States. The plant serves a population of approximately 13,200 residents in the Prouts Neck area, a coastal community along the Atlantic Ocean. As a municipal facility, it plays a key role in managing wastewater for this part of southern Maine. Under the U.S. Clean Water Act, facilities of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Maine Department of Environmental Protection. These permits set effluent limits to protect water quality. The treated effluent from Prouts Neck W P C F is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Scarborough River and nearby coastal waters. The receiving waters support diverse marine life and are part of a sensitive coastal ecosystem. Proper treatment is essential to prevent nutrient pollution and protect shellfish habitats and recreational waters in the region.

The plant discharges into the Scarborough River system, which flows into Saco Bay and the Gulf of Maine, part of the Atlantic Ocean. This coastal watershed supports important fisheries, including lobster and groundfish, and provides habitat for migratory birds. The area is ecologically sensitive due to its proximity to estuaries and salt marshes that filter pollutants and buffer storm surges.
