Etangs Cadillac Wastewater Treatment Plant, Rouyn-Noranda, Québec

Etangs Cadillac is a wastewater treatment plant located in Rouyn-Noranda, Québec, Canada, serving a small population of 1,154 residents. The facility is situated in the Abitibi-Témiscamingue region, an area characterized by its boreal forest and numerous lakes. The plant provides secondary treatment, which is the standard biological treatment process required under Canadian federal and provincial regulations for communities of this size. Secondary treatment effectively removes organic matter and suspended solids, ensuring that the effluent meets environmental quality standards before discharge. The treated wastewater is discharged into the local watershed, which ultimately drains into the Ottawa River basin and then into the St. Lawrence River. This waterway supports diverse aquatic life and is an important resource for communities downstream. The plant's operation helps protect the ecological health of these waters.

The plant discharges into the local watershed within the Ottawa River basin, which flows into the St. Lawrence River and eventually the Atlantic Ocean. The region's many lakes and rivers support a variety of fish species and provide habitat for migratory birds. Maintaining water quality is crucial for both ecological balance and recreational use.
