The plant plays a key role in protecting the ecological health of these waters, supporting aquatic life and recreational uses downstream.

The plant discharges into a tributary of the Schuylkill River, which flows into the Delaware River and then to Delaware Bay. The watershed supports diverse aquatic species and provides drinking water for millions. Advanced treatment helps reduce nutrient loading, protecting the bay's sensitive estuarine ecosystem from eutrophication.
