The facility serves a population of 9,465 and is part of the state's correctional infrastructure. Its inland location places it within the Delaware River watershed. The plant operates under the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For facilities serving populations around 10,000, secondary treatment is typically mandated, with additional nutrient controls in sensitive watersheds. The treated effluent from this plant likely discharges to a tributary of the Perkiomen Creek, which flows into the Schuylkill River and ultimately the Delaware River and Delaware Bay. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's performance is critical for maintaining water quality in this region.

The plant discharges into the Perkiomen Creek watershed, a tributary of the Schuylkill River, which flows into the Delaware River and Delaware Bay. This region supports diverse aquatic ecosystems, including migratory fish species such as American shad and river herring. The Schuylkill River is a major drinking water source for Philadelphia, making nutrient and pollutant control essential for downstream water quality.
