Overview
Etangs Aerés Saint Prosper is an operational wastewater treatment plant in Saint-Prosper, Québec, Canada, serving a population of 1,810. It discharges treated effluent into local waterways within the Chaudière-Appalaches region.
Etangs Aerés Saint Prosper is a municipal wastewater treatment facility located in Saint-Prosper, a community within the Les Etchemins region of Chaudière-Appalaches, Québec, Canada. The plant serves a population of approximately 1,810 residents, reflecting its role in managing domestic wastewater for a small rural agglomeration. As a Canadian facility, the plant operates under provincial regulations administered by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC) of Québec. For small communities like Saint-Prosper, typical treatment involves aerated lagoons or similar systems designed to meet effluent quality standards for organic matter and suspended solids. The plant's design and operation align with Québec's wastewater treatment objectives for smaller populations. The treated effluent from Etangs Aerés Saint Prosper is discharged into a local watercourse that ultimately drains into the Chaudière River, a major tributary of the St. Lawrence River. This watershed supports diverse aquatic life and provides habitat for fish species such as brook trout and Atlantic salmon. The plant's discharge contributes to the overall water quality management of the Chaudière River basin.
Environmental context
