Keeseville V STP - Clinton County, New York Wastewater Treatment Plant

Keeseville V STP is a wastewater treatment facility located in the town of AuSable, Clinton County, New York, serving a population of 1,750. The plant is situated near the western shore of Lake Champlain, a major freshwater body that forms part of the border between New York and Vermont. As a small-scale municipal plant, it plays a key role in managing local wastewater for the community. Under the US Clean Water Act, facilities of this size are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. These permits set effluent limits to protect water quality in receiving waters. The plant's treated effluent likely discharges into a tributary of Lake Champlain, which ultimately drains northward via the Richelieu River into the St. Lawrence River and the Atlantic Ocean. Lake Champlain is an ecologically significant water body that supports diverse aquatic life, including native fish species and migratory birds. The plant's operations contribute to protecting the lake's water quality from nutrient pollution and other contaminants.

Keeseville V STP discharges into the Lake Champlain basin, a large freshwater lake that drains north via the Richelieu River to the St. Lawrence River and the Atlantic Ocean. Lake Champlain supports diverse aquatic ecosystems, including cold-water fisheries and migratory waterfowl. The plant's location within 50 km of the lake underscores its role in safeguarding this important water resource from nutrient enrichment and other pollutants.
