Etangs Aeres Wastewater Treatment Plant, Farnham, Quebec

Etangs Aeres is a wastewater treatment plant located in Farnham, Quebec, Canada, serving a small community of 579 residents. The plant operates under the regulatory framework of the Canadian Environmental Protection Act and provincial Quebec regulations, which set standards for effluent quality and environmental protection. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. In Canada, such facilities are typically subject to federal and provincial permits that ensure compliance with water quality guidelines. The treated effluent is discharged into local waterways that eventually drain into the Yamaska River, a tributary of the St. Lawrence River. This watershed supports diverse aquatic life and is important for regional water resources. The plant's operation helps protect downstream ecosystems from nutrient pollution and other contaminants.

The plant discharges into the Yamaska River basin, which flows into the St. Lawrence River and ultimately the Atlantic Ocean. This watershed supports a variety of fish species and provides habitat for migratory birds. The secondary treatment process reduces organic load and helps maintain water quality in the river, which is important for both ecological health and downstream communities.
