Usine d epuration de Baldwin - Secondary Wastewater Treatment Plant in Coaticook, Quebec

Usine d epuration de Baldwin is a municipal wastewater treatment facility located in Coaticook, Quebec, Canada. The plant serves a small population of 212 residents and operates as a secondary treatment facility, ensuring compliance with Canadian federal and provincial wastewater regulations. The plant provides secondary treatment, which involves biological processes to remove organic matter and suspended solids. As a small-scale facility in Quebec, it operates under the provincial Reglement sur l'assainissement des eaux usees municipales, which sets effluent standards for municipal wastewater. The plant's discharge volume of 95.00 cubic meters per day reflects its small service area. The treated effluent is discharged into a local watercourse that flows into the Coaticook River, a tributary of the Saint-Francois River, which ultimately drains into Lake Saint-Pierre and the St. Lawrence River. The plant plays a key role in protecting the water quality of these downstream ecosystems, which support diverse aquatic life and recreational activities.

The plant discharges into a local stream that feeds the Coaticook River, part of the Saint-Francois River basin. This watershed drains into Lake Saint-Pierre, a fluvial lake on the St. Lawrence River that is ecologically sensitive due to its role as a migratory stopover for waterfowl and a spawning ground for fish. The secondary treatment provided by the plant helps reduce nutrient and organic pollution, protecting downstream aquatic habitats.
