Saint Pierre de l ile d Orleans Wastewater Treatment Plant, Quebec

Saint Pierre de l ile d Orleans is a municipal wastewater treatment plant located on Île d'Orléans in the Capitale-Nationale region of Quebec, Canada. The plant serves a small population of 1,811 residents in the community of Saint-Pierre-de-l'Île-d'Orléans, situated along the St. Lawrence River. The plant provides 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 reduce organic matter and suspended solids before discharge. The plant operates with a daily discharge volume of 813.30 cubic meters, reflecting the scale of the small agglomeration it serves. The treated effluent is discharged into the St. Lawrence River, one of North America's most significant waterways. The St. Lawrence River drains into the Gulf of St. Lawrence and eventually the Atlantic Ocean. The plant's location within 10 km of the coast means its discharge can influence the river's estuarine environment, which supports diverse aquatic life including fish species and migratory birds.

The plant discharges into the St. Lawrence River, which flows into the Gulf of St. Lawrence and the Atlantic Ocean. The river's estuary is ecologically sensitive, supporting diverse aquatic life such as beluga whales, fish species, and migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads to this important waterway.
