Gentilly Wastewater Treatment Plant, Bécancour, Québec

The Gentilly wastewater treatment plant is located in the Bécancour region of Québec, Canada, serving a population of approximately 2,623. As a municipal facility, it plays a key role in managing wastewater for this small community within the Centre-du-Québec administrative region. Under Canadian federal and provincial regulations, wastewater treatment plants of this scale are typically required to meet secondary treatment standards or equivalent. The plant operates under Québec's environmental quality framework, which aligns with national wastewater systems effluent regulations (WSER) that set discharge quality standards for all facilities. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River, one of North America's most significant waterways. The St. Lawrence River supports diverse aquatic ecosystems and is a critical migratory corridor for fish species. Proper treatment helps protect downstream water quality and ecological health.

The plant discharges into the St. Lawrence River basin, a major waterway that flows from the Great Lakes to the Atlantic Ocean. The river supports a wide range of aquatic life, including fish species such as Atlantic sturgeon and American eel, and serves as an important migratory route. The local watershed in the Bécancour area is characterized by agricultural and forested lands, making nutrient management a key consideration for protecting downstream ecosystems.
