Etangs Evain Wastewater Treatment Plant, Rouyn-Noranda, Québec

Etangs Evain is a wastewater treatment plant located at 147 Avenue Lafontaine in the Évain sector of Rouyn-Noranda, Québec, Canada. The plant serves a population of about 2,929 residents and is part of the municipal wastewater infrastructure for the Abitibi-Témiscamingue region. As a small-scale facility in Canada, the plant operates under provincial and federal regulations, including the Canadian Environmental Protection Act and Québec's Environment Quality Act. These regulations require appropriate treatment to protect receiving waters. The plant's designed capacity is 1.00 million liters per day, indicating it is sized for a small community. The treated effluent from Etangs Evain is discharged into local waterways that drain into the Lake Timiskaming watershed, part of the larger Ottawa River basin. This region supports diverse aquatic life and is important for recreational activities and local ecosystems. Proper treatment helps maintain water quality in downstream lakes and rivers.

The plant discharges into the Lake Timiskaming watershed, which flows into the Ottawa River and eventually the St. Lawrence River. This watershed supports a variety of fish species and is used for recreation. The area's cold climate and seasonal variations require robust treatment to protect sensitive aquatic habitats during low-flow periods.
