Eagle Lake WW TF - Fort Kent, Maine Wastewater Treatment Plant

Eagle Lake WW TF is a municipal wastewater treatment facility located in Fort Kent, Aroostook County, Maine, United States. The plant serves a small population of 795 residents, providing secondary treatment to meet Clean Water Act standards. The plant has a designed capacity of 529.96 thousand cubic meters per year and currently treats a discharge volume of 302.83 thousand cubic meters annually. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharge. Under the U.S. EPA National Pollutant Discharge Elimination System (NPDES), plants of this scale must comply with effluent limits to protect water quality. The treated effluent is discharged into local streams that drain into the St. John River, a major waterway flowing through Maine and New Brunswick, Canada, ultimately reaching the Bay of Fundy. The plant plays a key role in protecting downstream aquatic habitats and maintaining the ecological health of the St. John River basin.

The plant discharges into tributaries of the St. John River, which flows northeast through Maine and into New Brunswick, Canada, before emptying into the Bay of Fundy. The St. John River supports diverse fish populations, including Atlantic salmon and brook trout, and its estuary is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient loading and protect these downstream ecosystems.
