etangs aeres Wemotaci Wastewater Treatment Plant, La Tuque, Quebec

The etangs aeres Wemotaci wastewater treatment plant serves the community of Wemotaci in La Tuque, Quebec, Canada. This facility is operational and provides secondary treatment for a population of approximately 1,028 residents. The plant discharges an average of 650 cubic meters of treated wastewater per day. As a secondary treatment plant, it meets the standard requirements under Canadian federal and provincial regulations, which mandate secondary treatment for municipal wastewater to reduce organic matter and suspended solids. The plant's scale places it in the small community category, where lagoon-based or aerated systems are common. The treated effluent is discharged into local waterways that drain into the Saint-Maurice River, a major tributary of the St. Lawrence River. This river system supports diverse aquatic life and is important for regional ecology. The plant's operation helps protect downstream water quality in the St. Lawrence River watershed.

The plant discharges into the Saint-Maurice River basin, which flows into the St. Lawrence River and ultimately the Gulf of St. Lawrence. This watershed supports diverse fish species, including walleye and brook trout, and provides habitat for migratory birds. The secondary treatment process reduces nutrient and organic loading, helping to maintain the ecological health of the river system.
