etang aeree sainte luce secteur sainte luce - Sainte-Luce, Quebec Wastewater Treatment Plant

The etang aeree sainte luce secteur sainte luce wastewater treatment plant is a municipal facility located in Sainte-Luce, a small community in the Bas-Saint-Laurent region of Quebec, Canada. The plant serves a population of 423 and provides secondary treatment, which is the minimum standard for wastewater treatment in Canada under the federal Wastewater Systems Effluent Regulations (WSER). The plant discharges an average of 190 cubic meters of treated wastewater per day. As a small-scale facility, it operates under provincial regulations administered by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC) of Quebec. The plant's proximity to the coast means its effluent enters the St. Lawrence River estuary, a major ecological transition zone between freshwater and marine environments. The receiving water body is the St. Lawrence River, which flows into the Gulf of St. Lawrence and ultimately the Atlantic Ocean. The estuary supports diverse aquatic life, including fish species such as Atlantic salmon and sturgeon, and serves as a critical migratory corridor for birds and marine mammals. The plant's secondary treatment helps protect this sensitive ecosystem from nutrient pollution and pathogens.

The plant discharges into the St. Lawrence River estuary, a dynamic ecosystem where freshwater from the Great Lakes meets the saltwater of the Atlantic Ocean. This estuary supports a rich diversity of life, including fish, invertebrates, and migratory birds. The downstream environment includes the Gulf of St. Lawrence, which is an important fishing ground and marine habitat. The plant's secondary treatment reduces organic matter and suspended solids, helping to maintain water quality in this ecologically sensitive area.
