etangs aeres is a municipal wastewater treatment plant located in Saint-Zotique, Quebec, Canada. The plant serves a population of approximately 8,733 residents, making it a medium-sized facility within the region. It is situated inland, more than 50 km from the coast, and operates under the regulatory framework of Quebec's environmental laws. As a Canadian treatment plant, etangs aeres is subject to the federal Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which mandate minimum secondary treatment or equivalent for most facilities. For a plant serving around 8,700 people, typical treatment includes biological processes to reduce organic matter and suspended solids. The plant's operational status is confirmed as active, contributing to the local wastewater management infrastructure. The treated effluent from etangs aeres is discharged into a receiving water body that ultimately drains into the St. Lawrence River, a major waterway flowing into the Atlantic Ocean. The St. Lawrence River supports diverse aquatic life and is an important ecological corridor. The plant's operations help protect downstream water quality in the St. Lawrence River and its tributaries.

The plant discharges into a local watercourse that flows into the St. Lawrence River, one of North America's largest rivers. The St. Lawrence River supports a rich ecosystem, including fish species such as sturgeon and walleye, and serves as a critical migratory route for birds. Downstream, the river empties into the Gulf of St. Lawrence, a biologically productive marine environment. Protecting water quality in this watershed is essential for maintaining aquatic biodiversity and supporting local communities.
