Etang Wastewater Treatment Plant, Price, Québec, Canada

The Etang wastewater treatment plant is located in Price, a municipality in the La Mitis region of Bas-Saint-Laurent, Québec, Canada. It serves a population of approximately 2,227 people, making it a small-scale facility within the province's wastewater infrastructure. As a Canadian facility, the plant operates under Québec's environmental regulations, which align with the federal Fisheries Act and the Canadian Environmental Protection Act. For small agglomerations like Price, secondary treatment is typically required to protect receiving waters. The regulatory framework ensures that effluent quality meets provincial standards for parameters such as biochemical oxygen demand and total suspended solids. The plant's treated effluent ultimately discharges into the St. Lawrence River watershed, which drains into the Gulf of St. Lawrence and the Atlantic Ocean. The receiving environment supports diverse aquatic life, including fish species such as Atlantic salmon and brook trout, and is an important migratory corridor for birds. The proximity to the coast (within 50 km) underscores the need for effective treatment to protect downstream marine ecosystems.

The plant discharges into the St. Lawrence River watershed, which flows into the Gulf of St. Lawrence and the Atlantic Ocean. This region supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. The coastal proximity means that treated effluent must meet stringent standards to prevent nutrient enrichment and protect marine life in the downstream estuary.
