Station d epuration is a municipal wastewater treatment plant located in La Malbaie, Quebec, Canada, along Boulevard Malcolm-Fraser in the Cap-à-l'Aigle area. The plant serves a population of approximately 5,424 residents and is part of the region's essential water infrastructure. Its designed capacity is 1.00 million liters per day, reflecting the scale of this small community. As a Canadian facility, the plant operates under Quebec's environmental regulations, which align with federal standards under the Canadian Environmental Protection Act and the Fisheries Act. For a plant of this size, secondary treatment is typically required to protect receiving waters. The plant's operational status is confirmed as active, ensuring ongoing treatment of municipal wastewater. The plant's treated effluent ultimately reaches the St. Lawrence River, a major waterway that flows into the Gulf of St. Lawrence and the Atlantic Ocean. This river system supports diverse aquatic life, including fish species such as Atlantic salmon and sturgeon, and provides critical habitat for migratory birds. The plant's location within 50 km of the coast underscores its role in protecting downstream estuarine and marine environments.

The plant discharges into the St. Lawrence River, which flows northeast through Quebec into the Gulf of St. Lawrence and then the Atlantic Ocean. This watershed supports a rich ecosystem, including fish spawning grounds and migratory bird routes. The plant's proximity to the coast (within 50 km) means its effluent can influence estuarine and marine water quality, making effective treatment important for ecological health.
