Byron T 3 STP s and Onsites - Secondary Wastewater Treatment Plant in Town of Byron, New York

Byron T 3 STP s and Onsites is a municipal wastewater treatment facility located in the Town of Byron, Genesee County, New York. The plant serves a small population of around 720 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 317.97 units and a current discharge volume of 208.20 units, the facility operates below its maximum capacity. The treated effluent is discharged into a local water body, likely a tributary of the Genesee River, which flows north into Lake Ontario. The plant's location more than 10 km from the coast reduces direct marine impact, but its discharge contributes to the Great Lakes basin, a sensitive freshwater ecosystem. Protecting water quality in this region is critical for drinking water, recreation, and aquatic life.

The plant discharges into a local watercourse that drains into the Genesee River, which flows northward into Lake Ontario, part of the Great Lakes system. This watershed supports diverse aquatic species and provides drinking water for millions. The secondary treatment helps reduce nutrient and pollutant loads, but the plant's location within 50 km of Lake Ontario means its effluent can influence nearshore water quality, particularly during low-flow conditions.
