The treated effluent from Green Valley WWTP is likely discharged into a local watercourse that drains into the St. Lawrence River, which ultimately flows into the Gulf of St. Lawrence and the Atlantic Ocean. The plant's location in the St. Lawrence River watershed means its operations are important for protecting downstream aquatic ecosystems, including fish habitats and water quality in the river system.

Green Valley WWTP discharges into a local tributary that flows into the St. Lawrence River, a major waterway connecting the Great Lakes to the Atlantic Ocean. The St. Lawrence River supports diverse aquatic life, including fish species such as walleye and yellow perch, and provides critical habitat for migratory birds. The plant's effluent quality is regulated to protect this sensitive river ecosystem from nutrient enrichment and contaminants.
