The plant's operational status is confirmed, and it plays a key role in protecting local water quality. The treated effluent is discharged into a local watercourse that eventually drains into the L'Assomption River, a tributary of the St. Lawrence River. This river system supports diverse aquatic life and is important for regional ecology. The plant's operation helps maintain the health of these downstream waters.

The plant discharges into a local watercourse that flows into the L'Assomption River, which ultimately joins the St. Lawrence River near Montreal. The St. Lawrence River is a major ecological corridor supporting fish species such as lake sturgeon and American eel, and its estuary is a critical habitat for migratory birds. The plant's treatment helps reduce nutrient and pollutant loads, protecting this sensitive downstream environment.
