Station d'epuration Fabreville - Laval, Quebec Wastewater Treatment Plant

Station d'epuration Fabreville is a wastewater treatment plant located in the Fabreville district of Laval, Quebec, Canada. It serves a population of approximately 99,000 residents, making it a medium-to-large agglomeration within the region. The plant is part of Laval's municipal wastewater infrastructure, which manages effluent from residential and commercial sources. As an operational facility, the plant is subject to Canada's Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which mandate minimum secondary treatment standards for facilities of this scale. The regulatory framework also includes provincial oversight by the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC) of Quebec, ensuring compliance with discharge limits for conventional pollutants. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River, one of North America's major waterways. The St. Lawrence River supports diverse aquatic ecosystems and is a critical migratory corridor for fish species such as Atlantic salmon and American eel. Proper treatment at this plant helps protect water quality in the river and downstream environments, including the Gulf of St. Lawrence.

The plant discharges into the St. Lawrence River watershed, a major waterway that flows from the Great Lakes to the Atlantic Ocean. The river supports a rich aquatic ecosystem, including fish species like lake sturgeon and yellow perch, and serves as a vital migratory route for eels and salmon. Downstream, the river transitions into the St. Lawrence Estuary and Gulf, which are ecologically sensitive areas supporting marine mammals and seabirds. Effective wastewater treatment at this plant is essential to maintain water quality and protect these downstream habitats.
