Station epuration St Benoit Labre - Wastewater Treatment Plant in Saint-Benoît-Labre, Québec

Station epuration St Benoit Labre is a municipal wastewater treatment facility located at 26, Rue Industrielle in Saint-Benoît-Labre, Québec, Canada. The plant serves a small population of 379 residents in the Beauce-Sartigan region of Chaudière-Appalaches. The plant provides secondary treatment, which is the standard biological treatment stage required under Canadian federal and provincial regulations for communities of this size. In Canada, wastewater treatment is governed by the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which sets national effluent quality standards for secondary treatment. The treated effluent is discharged into local waterways that ultimately drain into the Chaudière River, a tributary of the St. Lawrence River. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life and migratory fish species. The plant's operations help protect downstream water quality in this sensitive watershed.

The plant discharges into the Chaudière River basin, which flows northward into the St. Lawrence River near Québec City. The St. Lawrence River is a critical freshwater ecosystem supporting fish populations such as Atlantic sturgeon and American eel, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads to this important waterway.
