Usine d'epuration des eaux usees is a municipal wastewater treatment facility located in Sainte-Émélie-de-l'Énergie, a small community in the Lanaudière region of Québec, Canada. The plant serves a population of approximately 513 residents, reflecting its role in managing wastewater for a rural agglomeration. The plant provides secondary treatment, which is the standard level required under Canadian federal and provincial regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges an average daily volume of 230.20 cubic meters of treated effluent. The treated effluent is released into local watercourses that drain into the L'Assomption River watershed, which ultimately flows into the St. Lawrence River. This downstream connection highlights the plant's role in protecting the St. Lawrence River ecosystem, a major waterway supporting diverse aquatic life and serving as a critical migratory corridor for fish and birds.

The plant discharges into local streams that feed the L'Assomption River, a tributary of the St. Lawrence River. The St. Lawrence River is a major ecological corridor in North America, supporting diverse fish species, including Atlantic sturgeon and American eel, and providing habitat for migratory waterfowl. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in this sensitive watershed.
