Chaumont V STP - Secondary Wastewater Treatment in Village of Chaumont, New York

Chaumont V STP is a municipal wastewater treatment facility located in the Village of Chaumont, Jefferson County, New York. The plant serves a small population of 592 residents and operates as part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities. With a designed capacity of 340,690 gallons per day and a current discharge volume of 227,130 gallons per day, the plant operates below its capacity, indicating room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into Lake Ontario, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's coastal location within 10 km of Lake Ontario underscores the importance of effective treatment to protect this sensitive ecosystem.

The plant's discharge enters a tributary of the Chaumont River, which flows into the Chaumont Bay of Lake Ontario. Lake Ontario is a critical freshwater resource, supporting fisheries, recreation, and municipal water supplies. The bay area is ecologically sensitive, providing habitat for fish spawning and migratory birds. Effective secondary treatment helps reduce nutrient loading and protect water quality in this coastal environment.
