Station d'épuration de Bromptonville - Sherbrooke, Québec Wastewater Treatment Plant

Station d'épuration de Bromptonville is a municipal wastewater treatment plant located in the Brompton sector of Sherbrooke, Québec, Canada. It serves a population of approximately 5,123 residents, classifying it as a small agglomeration under Canadian wastewater management frameworks. As a small-scale facility, the plant is expected to meet provincial treatment standards set by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC) of Québec. These standards typically require secondary treatment or equivalent to protect receiving water quality, in line with the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. The plant discharges treated effluent into the Saint-François River, which flows into Lac Saint-Pierre and eventually the St. Lawrence River. This watershed supports diverse aquatic life and is an important ecological corridor in the Estrie region. The plant plays a key role in maintaining water quality in this sensitive freshwater system.

The plant discharges into the Saint-François River, a tributary of the St. Lawrence River via Lac Saint-Pierre. The Saint-François River basin supports diverse fish species and provides habitat for migratory birds. The St. Lawrence River downstream is a major freshwater ecosystem that sustains commercial fisheries and recreational activities. Protecting water quality in this watershed is critical for ecological health and human use.
