STEU Beaupre Wastewater Treatment Plant, Beaupré, Québec

STEU Beaupre is a municipal wastewater treatment facility located at 58 Rue Industrielle in Beaupré, Québec, within the Capitale-Nationale region. The plant serves a population of roughly 5,958 residents, placing it in the small-to-medium agglomeration category under Canadian wastewater management frameworks. As an operational plant, STEU Beaupre is subject to Québec's provincial environmental regulations and Canada's federal wastewater standards, which require secondary treatment for facilities of this scale. The plant's designed capacity is 1.00 million litres per day, reflecting its role in managing local domestic wastewater. The plant's treated effluent ultimately reaches the St. Lawrence River via local tributaries, contributing to the broader St. Lawrence watershed. This river system supports diverse aquatic life and is a critical migratory corridor for fish species. The plant's location within 50 km of the coast underscores its proximity to sensitive estuarine environments.

STEU Beaupre discharges into the St. Lawrence River watershed, one of Canada's largest and most ecologically significant river systems. The St. Lawrence River flows into the Gulf of St. Lawrence, supporting diverse aquatic habitats and migratory fish populations. The plant's proximity to the coast (within 50 km) means its effluent can influence estuarine conditions, making treatment quality important for downstream ecosystem health.
