Usine d'epuration Achille Gagnon - Victoriaville, Quebec Wastewater Treatment Plant

Usine d'epuration Achille Gagnon is the municipal wastewater treatment plant for Victoriaville, a city in the Centre-du-Quebec region of Quebec, Canada. The plant serves a population of approximately 48,340, classifying it as a medium-sized agglomeration under Canadian wastewater management standards. As an operational facility, the plant is subject to Quebec's environmental regulations and the federal Canadian Environmental Protection Act. For a community of this size, secondary treatment is typically required, and the plant likely employs biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is released into a local watercourse that flows into the St. Lawrence River, one of Canada's most significant waterways. The St. Lawrence River supports diverse aquatic life and is a critical migratory corridor for fish species such as Atlantic salmon and American eel. The plant's operations help protect downstream water quality in the St. Lawrence ecosystem.

The plant discharges into a tributary of the St. Lawrence River, which ultimately drains into the Gulf of St. Lawrence and the Atlantic Ocean. The St. Lawrence River is ecologically significant, supporting diverse fish populations and serving as a major migratory route. Protecting water quality in this watershed is essential for maintaining the health of downstream aquatic habitats and the broader marine environment.
