Station d epuration des eaux usees - Saint-Jean-de-Matha, Quebec Wastewater Treatment Plant

Station d epuration des eaux usees is a municipal wastewater treatment plant located in Saint-Jean-de-Matha, a small town in the Lanaudière region of Quebec, Canada. The plant serves a population of approximately 2,020 residents and operates under secondary treatment standards. As a secondary treatment facility, the plant uses biological processes to reduce organic matter and suspended solids, meeting the typical requirements for inland communities in Canada. Canadian wastewater facilities are regulated under provincial and federal guidelines, including the Fisheries Act and provincial environmental quality laws. The treated effluent is released into a local watercourse that drains into the L'Assomption River, which flows southward into the St. Lawrence River near Montreal. 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 river system.

The plant discharges into a tributary of the L'Assomption River, which flows into the St. Lawrence River near Montreal. The St. Lawrence River is a critical freshwater ecosystem supporting over 100 fish species and serving as a major migratory route for birds. The plant's secondary treatment reduces nutrient and organic loads, helping to maintain water quality in this ecologically significant river system.
