Station epuration St Robert Bellarmin - Wastewater Treatment Plant in Saint-Robert-Bellarmin, Quebec

Station epuration St Robert Bellarmin is a municipal wastewater treatment facility located in Saint-Robert-Bellarmin, a small community in the Estrie region of Quebec, Canada. The plant serves a population of 285 and provides secondary treatment, which is appropriate for a small agglomeration under Canadian wastewater regulations. The plant operates under Quebec's provincial environmental regulations, which align with the federal Wastewater Systems Effluent Regulations (WSER) under the Canadian Environmental Protection Act. These regulations mandate secondary treatment or equivalent for all municipal wastewater systems, ensuring that effluent meets national quality standards for carbonaceous matter, suspended solids, and residual chlorine. The treated effluent is discharged into local waterways that drain into the Saint-François River basin, eventually reaching the St. Lawrence River. The plant plays a key role in protecting the water quality of the surrounding watershed, which supports aquatic life and recreational activities in the region.

The plant discharges into the Saint-François River watershed, which flows into the St. Lawrence River, one of North America's largest and most ecologically significant waterways. The St. Lawrence River supports diverse aquatic species, including fish like Atlantic salmon and lake sturgeon, and is a critical migratory corridor for birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream ecosystems from eutrophication and oxygen depletion.
