The plant serves a population of approximately 17,600 residents, placing it in the medium-agglomeration category under US regulatory frameworks. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. For plants of this scale, secondary treatment is typically required, with additional nutrient removal in sensitive watersheds. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Long Island Sound. This water body supports diverse aquatic life and is an important ecological and recreational resource for the region.

The plant discharges into the Long Island Sound via local tributaries. The Sound is a tidal estuary that supports diverse marine life, including finfish, shellfish, and migratory birds. Nutrient loading from wastewater can contribute to eutrophication, making effective treatment critical for maintaining water quality and ecosystem health.
