The treated effluent from Lyons Falls V STP is discharged into a local receiving water body, which ultimately drains into the Black River watershed and then into Lake Ontario. This makes the plant's operations important for protecting the ecological health of the Black River and the broader Lake Ontario basin, which supports diverse aquatic life and recreational activities.

The plant discharges into a local waterway that flows into the Black River, a tributary of Lake Ontario. The Black River watershed supports diverse fish populations and provides habitat for migratory birds. Lake Ontario, part of the Great Lakes system, is a critical freshwater resource that requires careful management of nutrient and pollutant inputs to prevent eutrophication and protect drinking water supplies.
