Orleans T La Fargeville SD STP - Secondary Wastewater Treatment in La Fargeville, New York

Orleans T La Fargeville SD STP is a municipal wastewater treatment facility located in La Fargeville, a hamlet in Jefferson County, New York. The plant serves a small population of 430 residents and operates under secondary treatment, which is the minimum standard for municipal wastewater in the United States under the Clean Water Act. The plant has a designed capacity of 242.27 million gallons per day and currently discharges 155.20 million gallons per day, indicating it operates below capacity. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids before discharge. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. The treated effluent is discharged into a receiving water body that ultimately flows into the St. Lawrence River, a major waterway connecting the Great Lakes to the Atlantic Ocean. The plant's proximity to the St. Lawrence River and Lake Ontario (within 10 km of the coast) means its discharge can affect sensitive aquatic ecosystems, including fish spawning grounds and migratory bird habitats.

The plant discharges into a tributary of the St. Lawrence River, which drains into the Gulf of St. Lawrence and the Atlantic Ocean. The St. Lawrence River supports diverse aquatic life, including lake sturgeon and American eel, and is an important migratory corridor for fish and birds. The plant's coastal location within 10 km of Lake Ontario means its effluent can influence nearshore water quality and nutrient levels in the Great Lakes basin.
