The plant serves a population of approximately 2,538 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional nutrients and contaminants. Its designed capacity is 416.39 million gallons per year, and it currently discharges 416.40 million gallons annually, indicating full utilization. The facility is operated as part of the local municipal infrastructure, ensuring compliance with state and federal water quality standards. The treated effluent is discharged into a receiving water body within the Delaware River Basin, which ultimately drains to the Delaware Bay and the Atlantic Ocean. The plant plays a key role in protecting the ecological health of local streams and the downstream estuary, supporting aquatic life and recreational uses.

The plant discharges into a tributary of the Schuylkill River, which flows into the Delaware River and then to Delaware Bay. The Delaware River Basin supports diverse aquatic species, including migratory fish like American shad and Atlantic sturgeon. The advanced treatment helps reduce nutrient loading, protecting downstream water quality in the ecologically sensitive Delaware Estuary.
