The plant's operations are critical for protecting downstream water quality and the health of Long Island Sound's estuarine ecosystem.

The plant discharges into the Quinebaug River, which flows into the Shetucket River, then the Thames River, and ultimately into Long Island Sound. This watershed supports diverse aquatic species and is an important migratory corridor for fish. The Sound's estuarine environment is sensitive to nutrient loading, making effective wastewater treatment essential for maintaining ecological balance.
