Station d epuration Wastewater Treatment Plant, Rivière-du-Loup, Québec

Station d epuration is a municipal wastewater treatment facility located in Rivière-du-Loup, Québec, Canada. The plant serves a population of approximately 17,826 residents in the Bas-Saint-Laurent region. It is situated near the St. Lawrence River, a major waterway that ultimately drains into the Atlantic Ocean. As a Canadian wastewater treatment plant, it operates under the federal Wastewater Systems Effluent Regulations (WSER) and provincial environmental standards set by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC). For a community of this size, secondary treatment is typically required to meet effluent quality standards. The plant's designed capacity is 1.00 (likely in million liters per day or similar unit), indicating its scale. The plant's treated effluent is discharged into the St. Lawrence River, which supports diverse aquatic life and serves as a critical migratory corridor for fish and birds. The river flows into the Gulf of St. Lawrence and then the Atlantic Ocean. Proper treatment helps protect downstream ecosystems, including sensitive estuarine habitats.

The plant discharges into the St. Lawrence River, a major waterway that flows through Québec and into the Gulf of St. Lawrence, a large estuary that supports diverse marine life. The river is ecologically significant as a migration route for species such as Atlantic salmon and beluga whales. The surrounding watershed includes agricultural and forested areas, and the plant's operations help maintain water quality in this important ecosystem.
