S Burlington Arpt Pkwy WP Wastewater Treatment Plant, South Burlington, Vermont

S Burlington Arpt Pkwy WP is a municipal wastewater treatment plant located at 700 Airport Parkway in South Burlington, Vermont. Serving an estimated population of 16,089, the plant is part of the region's wastewater infrastructure within Chittenden County. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Vermont Department of Environmental Conservation. For a population of this size, secondary treatment is the federal minimum standard, with potential for additional nutrient removal given the sensitive nature of the Lake Champlain basin. The plant's treated effluent ultimately drains into the Lake Champlain watershed, a large freshwater lake that supports diverse aquatic life and serves as a critical regional water resource. The lake drains north via the Richelieu River into the St. Lawrence River and eventually the Atlantic Ocean.

The plant discharges into the Lake Champlain basin, a major freshwater lake that spans the Vermont-New York border and extends into Quebec, Canada. Lake Champlain is ecologically sensitive due to nutrient loading concerns, particularly phosphorus, which can lead to algal blooms. The lake drains via the Richelieu River to the St. Lawrence River and the Atlantic Ocean, making local treatment practices important for downstream water quality.
