Vergennes WWTF - Wastewater Treatment Plant in Panton, Vermont

Vergennes WWTF is a municipal wastewater treatment facility located in Panton, Addison County, Vermont, United States. It serves a population of approximately 2,676 residents in the Vergennes area. The plant is situated near Lake Champlain, a major freshwater lake that drains into the Richelieu River and eventually the St. Lawrence River. As a small-scale facility, Vergennes WWTF operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For plants serving fewer than 10,000 people, secondary treatment is typically mandated to protect water quality. The designed capacity of 1.00 million gallons per day aligns with the population served. The plant's treated effluent discharges into the Lake Champlain basin, a critical water body that supports diverse aquatic life and recreational activities. Lake Champlain is part of the larger St. Lawrence River watershed, which ultimately drains into the Atlantic Ocean. Protecting this waterway is essential for maintaining regional ecological health.

The plant discharges into the Lake Champlain basin, which flows north via the Richelieu River into the St. Lawrence River and then to the Atlantic Ocean. Lake Champlain is a large freshwater lake that supports diverse fish populations, including lake trout and landlocked Atlantic salmon, and serves as an important migratory corridor for birds. The watershed is sensitive to nutrient pollution, particularly phosphorus, which can cause algal blooms.
