Lyndonville V STP - Wastewater Treatment Plant in Village of Lyndonville, New York

Lyndonville V STP is a municipal wastewater treatment facility located in the Village of Lyndonville, Orleans County, New York. It serves a population of approximately 1,139 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal plants. The plant has a designed capacity of 567.81 million gallons per year and currently discharges 314.19 million gallons per year of treated effluent. The plant provides secondary treatment, a standard level for small communities in the United States. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale are typically permitted by the state environmental agency, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into Lake Ontario, part of the Great Lakes system. Lake Ontario is a critical freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant's proximity to the lake (within 10 km) underscores the importance of effective treatment to protect this sensitive ecosystem from nutrient pollution and pathogens.

The plant discharges into a tributary of Lake Ontario, the easternmost of the Great Lakes. Lake Ontario supports a diverse ecosystem including lake trout, salmon, and migratory birds. The lake is also a source of drinking water for surrounding communities. Effective wastewater treatment is crucial to prevent eutrophication and harmful algal blooms, which have been a concern in the Great Lakes basin due to nutrient loading.
