Dunkirk C WWTP is a municipal wastewater treatment facility serving the City of Dunkirk in Chautauqua County, New York. The plant handles wastewater for a population of about 14,013 residents, placing it in the medium-agglomeration category. It is situated near the shores of Lake Erie, one of the Great Lakes, which influences its environmental significance. As a U.S. facility, Dunkirk C WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. For plants serving populations of this size, secondary treatment is typically required, with additional nutrient removal standards applicable in the Great Lakes basin to address eutrophication concerns. The plant's designed capacity is 1.00 million gallons per day, indicating a scale appropriate for its service area. The treated effluent from Dunkirk C WWTP ultimately discharges into Lake Erie, part of the Great Lakes system that drains into the St. Lawrence River and then the Atlantic Ocean. Lake Erie supports diverse aquatic life, including important fish species, and is a vital freshwater resource for millions of people. The plant's operations are critical to protecting water quality in this ecologically sensitive Great Lake.

Dunkirk C WWTP discharges into Lake Erie, the fourth-largest of the Great Lakes, which flows via the Niagara River into Lake Ontario and then the St. Lawrence River to the Atlantic Ocean. Lake Erie is a biologically productive lake that supports a variety of fish species and migratory birds. The plant's location within 50 km of the coast means its effluent can influence nearshore water quality, making nutrient management important to prevent algal blooms.
