etangs aeres de Cookshire Wastewater Treatment Plant, Cookshire-Eaton, Quebec

etangs aeres de Cookshire is a municipal wastewater treatment plant located in Cookshire-Eaton, Quebec, Canada. The facility serves a population of approximately 1,934 residents in the Le Haut-Saint-François region. As a small-scale plant, it plays a key role in managing local wastewater for this rural community. Under Canadian federal and provincial regulations, wastewater treatment plants in Quebec are subject to the Quebec Environment Quality Act and the Canadian Wastewater Systems Effluent Regulations. For a plant serving fewer than 10,000 people, secondary treatment is typically required to meet effluent quality standards. The plant discharges treated effluent into a local watercourse within the Saint-François River watershed, which flows into the St. Lawrence River and eventually the Atlantic Ocean. The receiving environment supports aquatic life and is part of the broader St. Lawrence ecosystem, which is ecologically significant for fish habitats and migratory bird populations.

The plant's treated effluent enters a tributary of the Saint-François River, which drains into the St. Lawrence River and ultimately the Atlantic Ocean. The Saint-François River watershed supports diverse aquatic species and is an important corridor for migratory fish such as Atlantic salmon. The region's mixed forest and agricultural land use means the plant helps protect downstream water quality from nutrient loading and pathogens.
