The plant's treated effluent discharges into a local waterway that is part of the Susquehanna River basin, ultimately draining into the Chesapeake Bay. This places the plant within a watershed of significant ecological importance, as the Chesapeake Bay is the largest estuary in the United States and supports diverse aquatic life, including critical fish and shellfish habitats.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic species and serving as a critical migratory corridor for fish and birds. Nutrient loading from wastewater treatment plants in this basin is a key concern due to its impact on bay water quality and hypoxia.
