Station d'épuration Saint-Félix-de-Valois Wastewater Treatment Plant, Québec

Station d'épuration Saint-Félix-de-Valois is a municipal wastewater treatment facility located in Saint-Félix-de-Valois, Québec, Canada. Serving a population of approximately 3,443, the plant is part of the region's water infrastructure managed under Québec's environmental regulations. As a small-scale facility, the plant is expected to meet provincial treatment standards for wastewater. In Québec, municipal wastewater treatment is governed by the Règlement sur le traitement des eaux usées (RTEU), which sets effluent quality requirements based on population served and receiving environment sensitivity. Plants serving fewer than 10,000 people typically require secondary treatment or equivalent performance. The treated effluent is discharged into local waterways that drain into the Lanaudière region's watershed, ultimately reaching the St. Lawrence River. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life and serves as a critical freshwater resource for the region.

The plant discharges into the Lanaudière watershed, which flows into the St. Lawrence River, one of North America's largest rivers. The St. Lawrence River supports a rich ecosystem, including fish species such as Atlantic sturgeon and American eel, and provides drinking water for millions. The plant's treatment performance is important for protecting downstream water quality in this ecologically significant river system.
