As an advanced treatment plant, it provides a high level of pollutant removal to protect local water quality. The plant has a designed capacity of 264.98 million gallons per day and discharges a similar volume of treated wastewater.

Under the US Clean Water Act, the facility operates under an NPDES permit issued by the Pennsylvania Department of Environmental Protection, which sets effluent limits to safeguard receiving waters. The treated effluent from Bryn Athyn Boro STP ultimately drains into the Delaware River watershed, a major waterway that flows into Delaware Bay and the Atlantic Ocean. The plant's advanced treatment helps reduce nutrient loading and protect aquatic ecosystems in the region. The Delaware River supports diverse fish populations and serves as a drinking water source for millions.

The plant discharges into the Delaware River basin, which flows through Pennsylvania, New Jersey, and Delaware before emptying into Delaware Bay and the Atlantic Ocean. The Delaware River is a critical water resource, supporting migratory fish like American shad and providing habitat for freshwater mussels. Advanced treatment at this plant helps minimize nutrient pollution, which can cause algal blooms and oxygen depletion in the estuary.
