Powanl WPCF - North Pownal, Vermont Wastewater Treatment Plant

Powanl WPCF (Water Pollution Control Facility) is a municipal wastewater treatment plant located in North Pownal, Vermont, United States. The plant serves a small community of about 1,720 residents in the rural town of Pownal, situated in Bennington County near the border with New York and Massachusetts. As a secondary treatment facility, it provides biological treatment to remove organic matter and suspended solids from domestic wastewater. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Vermont Department of Environmental Conservation, governs the plant's discharge limits and monitoring requirements. With a designed capacity of 984.20 thousand gallons per day and an average daily flow of 329.33 thousand gallons per day, the plant operates well below its capacity, indicating room for future growth. Treated effluent from Powanl WPCF discharges into a local stream that flows into the Hoosic River, a tributary of the Hudson River. The Hoosic River watershed supports diverse aquatic life and provides recreational opportunities. The plant's discharge contributes to maintaining water quality in this ecologically sensitive region, which ultimately drains into the Atlantic Ocean via the Hudson River estuary.

Powanl WPCF discharges into a small tributary of the Hoosic River, which flows southward through Vermont, Massachusetts, and New York before joining the Hudson River near Mechanicville, New York. The Hudson River estuary is a critical habitat for migratory fish such as striped bass and American eel. The plant's secondary treatment helps protect downstream water quality in this ecologically important watershed, which supports diverse aquatic species and recreational uses.
