etangs Aeres Mt Carmel Wastewater Treatment Plant, Mont-Carmel, Québec

The etangs Aeres Mt Carmel wastewater treatment plant is located in Mont-Carmel, a small community in the Bas-Saint-Laurent region of Québec, Canada. The plant serves a population of approximately 690 residents and operates as a secondary treatment facility, which is standard for small communities in the province. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids from wastewater. The plant has a reported discharge volume of 310 cubic meters per day. Under Québec's environmental regulations, such facilities are required to meet effluent quality standards set by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC). The treated effluent from the plant is discharged into a local watercourse that ultimately flows into the St. Lawrence River, a major waterway that drains into the Atlantic Ocean. The St. Lawrence River supports diverse aquatic life and is an important ecological corridor in eastern Canada.

The plant's treated effluent enters a local tributary that flows into the St. Lawrence River, one of the largest rivers in North America. The St. Lawrence River and its estuary support a wide range of aquatic species, including fish, marine mammals, and migratory birds. The river's health is critical for both local ecosystems and downstream environments, including the Gulf of St. Lawrence and the Atlantic Ocean. Discharges from wastewater plants in the region are regulated to protect water quality and aquatic habitats.
