Les Éboulements Wastewater Treatment Plant | Quebec, Canada

Les Éboulements wastewater treatment plant is located in the municipality of Les Éboulements, Quebec, Canada, within the Charlevoix region. This small-scale facility serves a population of 434 residents, providing essential sanitation services to this rural community along the St. Lawrence River. The plant operates with secondary treatment, which is the standard level required under Canadian federal and provincial regulations for communities of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring that the effluent meets water quality standards before discharge. The plant is operational and discharges an average of 195 cubic meters of treated wastewater per day. The treated effluent from Les Éboulements is discharged into the local environment, ultimately reaching the St. Lawrence River, one of Canada's most significant waterways. The St. Lawrence River drains into the Gulf of St. Lawrence and then the Atlantic Ocean, supporting diverse aquatic ecosystems and serving as a critical migratory corridor for fish and birds. The plant's secondary treatment helps protect this sensitive downstream environment.

The plant discharges into the St. Lawrence River watershed, which flows into the Gulf of St. Lawrence and the Atlantic Ocean. This region supports diverse aquatic life, including fish species such as Atlantic salmon and sturgeon, and provides important habitat for migratory birds. The St. Lawrence River is ecologically sensitive, and secondary treatment helps reduce nutrient and pollutant loads that could contribute to eutrophication or harm aquatic ecosystems.
