Station d'epuration - Yamaska, Quebec Wastewater Treatment Plant

Station d'epuration is a municipal wastewater treatment plant located in Yamaska, Quebec, Canada. It serves a small community of 597 residents, providing secondary treatment to protect local water quality. The plant is situated in the Montérégie region, near the Yamaska River. As a secondary treatment facility, the plant meets the standard requirements under Canadian federal and provincial regulations, which mandate secondary treatment for most municipal wastewater. The plant's discharge volume of 268.00 cubic meters per day reflects its small scale, consistent with the population served. The treated effluent is discharged into the Yamaska River, which flows into the St. Lawrence River and eventually the Atlantic Ocean. The plant plays a key role in protecting the Yamaska River's water quality, supporting aquatic life and downstream ecosystems in the St. Lawrence River basin.

The plant discharges into the Yamaska River, a tributary of the St. Lawrence River, which ultimately drains into the Atlantic Ocean. The Yamaska River watershed supports diverse aquatic habitats and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating eutrophication risks in the St. Lawrence River system.
