This coastal drainage system supports diverse aquatic life and is ecologically sensitive. The plant plays a key role in maintaining the health of these downstream environments by reducing pollutant loads.

The plant discharges into the Piscataqua River watershed, which flows into the Gulf of Maine and the Atlantic Ocean. This coastal ecosystem supports a variety of marine species and is an important migratory corridor for fish. The region's cold-water habitats are sensitive to nutrient pollution, making effective wastewater treatment critical for preserving water quality and biodiversity.
