Bassin d epuration Wastewater Treatment Plant, Lac-Saguay, Quebec

Bassin d epuration is a wastewater treatment plant located in Lac-Saguay, a small municipality in the Laurentides region of Quebec, Canada. The plant serves a population of 9, making it one of the smallest municipal treatment facilities in the province. It is classified as operational and provides secondary treatment to the community's wastewater. The plant operates under Canada's federal and provincial wastewater regulations, which require secondary treatment for most municipal discharges. The Quebec Ministry of the Environment oversees compliance with the Provincial Water Quality Objectives. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Ottawa River basin. The plant's small scale and secondary treatment level help protect the surrounding lakes and rivers, which are important for recreation and aquatic habitat in the Laurentian region.

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 Laurentides region features numerous lakes and rivers that support diverse aquatic life, including fish species such as brook trout and lake trout. The plant's secondary treatment helps minimize nutrient and organic pollution, protecting downstream water quality.
