Overview
USINE D ePURATION MATANE is an operational wastewater treatment plant in Matane, Québec, Canada, serving approximately 6,938 people. It is located within 50 km of the coast and discharges into the St. Lawrence River estuary.
USINE D ePURATION MATANE is a municipal wastewater treatment facility located at 141 Rue Du Port in the industrial park of Matane, Québec, Canada. Serving a population of about 6,938, the plant is situated in the Bas-Saint-Laurent region along the south shore of the St. Lawrence River estuary. As a Canadian facility, it operates under provincial and federal environmental regulations, including the Quebec Environment Quality Act and the Canadian Fisheries Act, which govern effluent quality and receiving water protection. The plant's designed capacity is 1.00 million cubic meters per year, and it is currently operational. Canadian wastewater plants serving communities of this size typically employ secondary treatment or equivalent technologies to meet national effluent standards. The regulatory framework requires monitoring of key parameters such as biochemical oxygen demand, total suspended solids, and ammonia to protect aquatic life in the receiving environment. The treated effluent is discharged into the St. Lawrence River estuary, a major water body that flows into the Gulf of St. Lawrence and ultimately the Atlantic Ocean. The estuary supports diverse aquatic ecosystems, including fish species like Atlantic salmon and American eel, and is an important migratory corridor for birds. The plant's location near the coast underscores the need for effective treatment to minimize nutrient and contaminant loading to this sensitive marine environment.
Environmental context
The plant discharges into the St. Lawrence River estuary, which connects to the Gulf of St. Lawrence and the Atlantic Ocean. This estuarine environment supports a rich diversity of marine life, including fish, crustaceans, and marine mammals, and serves as a critical habitat for migratory birds. The region's cold waters and tidal dynamics influence pollutant dispersion, making effective wastewater treatment essential to protect downstream ecosystems and maintain water quality for recreational and commercial uses.
