Plattsburgh C WWTP - City of Plattsburgh, New York Wastewater Treatment Plant

Plattsburgh C WWTP is a municipal wastewater treatment facility serving the City of Plattsburgh in Clinton County, New York. The plant handles wastewater from a population of about 22,616, placing it in the medium-sized agglomeration category. It is situated near the shore of Lake Champlain, a major water body that drains northward into the Richelieu River and eventually the St. Lawrence River. 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 New York State Department of Environmental Conservation. For a plant of this scale, secondary treatment is typically required, with possible additional nutrient removal to protect sensitive water bodies like Lake Champlain. The designed capacity is reported as 1.00 (likely in million gallons per day), indicating a moderate-sized infrastructure. The plant's discharge ultimately reaches Lake Champlain, a large freshwater lake that supports diverse aquatic life and serves as a critical habitat for fish and migratory birds. The lake is part of the larger St. Lawrence River watershed, which flows into the Atlantic Ocean. Protecting water quality in this region is essential for recreation, drinking water, and ecological health.

The plant discharges into the Lake Champlain basin, which drains north via the Richelieu River into the St. Lawrence River and then the Atlantic Ocean. Lake Champlain is a large, ecologically sensitive freshwater lake that supports diverse fish species, including lake trout and landlocked Atlantic salmon, and provides critical habitat for migratory waterfowl. Nutrient loading from wastewater can contribute to algal blooms, making effective treatment important for maintaining water quality.
