TROY WPC Wastewater Treatment Plant, Troy, Vermont | Advanced Treatment for Lake Champlain Basin

TROY WPC is a municipal wastewater treatment facility located in Troy, Vermont, serving a population of approximately 6,063 residents. The plant is situated in Orleans County, a rural area in the northern part of the state, and operates under the regulatory framework of the United States Clean Water Act. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 3,028.32 cubic meters per day and a current discharge volume of 264.98 cubic meters per day, the facility operates well within its capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Vermont Department of Environmental Conservation, ensuring compliance with water quality standards. The treated effluent from TROY WPC is discharged into a receiving water body that ultimately drains into the Lake Champlain basin. Lake Champlain is a large freshwater lake shared by Vermont, New York, and Quebec, and is ecologically significant for its diverse aquatic life and recreational value. The plant's advanced treatment helps protect this sensitive watershed from nutrient pollution and other contaminants.

TROY WPC discharges into a tributary of the Missisquoi River, which flows north into Lake Champlain. Lake Champlain is a major freshwater lake that drains into the Richelieu River and eventually the St. Lawrence River. The watershed supports diverse aquatic ecosystems, including coldwater fisheries and migratory fish species. Advanced treatment at the plant helps reduce nutrient loading, which is critical for preventing algal blooms in Lake Champlain.
