Granville V STP - Village of Granville, New York Wastewater Treatment Plant

Granville V STP is a municipal wastewater treatment plant located in the Village of Granville, Washington County, New York. It serves a population of approximately 3,041 residents, classifying it as a small to medium agglomeration under U.S. regulatory frameworks. As a U.S. facility, the plant operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. For plants of this scale, secondary treatment is typically required to meet effluent standards for biochemical oxygen demand and total suspended solids. The plant discharges treated effluent into a local waterway that ultimately drains into the Lake Champlain basin, a major freshwater lake that flows north into the Richelieu River and eventually the St. Lawrence River. The receiving waters support diverse aquatic life and are important for regional recreation and ecology.

The plant's treated effluent enters a tributary of the Lake Champlain watershed, which drains into Lake Champlain and then via the Richelieu River to the St. Lawrence River. Lake Champlain is a large freshwater lake that supports diverse fish populations and serves as a critical habitat for migratory birds. The watershed is sensitive to nutrient loading, making effective wastewater treatment important for preventing eutrophication.
