Station d'epuration - Saint-Barthélemy, Québec Secondary Wastewater Treatment Plant

Station d'epuration is a municipal wastewater treatment plant located in Saint-Barthélemy, a small community in the Lanaudière region of Québec, Canada. The plant serves a population of approximately 805 residents and operates under secondary treatment standards, which is typical for small agglomerations in the province. As a secondary treatment facility, the plant uses biological processes to remove organic matter and suspended solids from wastewater. The plant's discharge volume is 361.30 units, and it operates under the regulatory framework of the Canadian Environmental Protection Act and Québec's provincial water quality regulations. For small communities like Saint-Barthélemy, secondary treatment is the standard requirement to protect receiving waters. The plant discharges treated effluent into the local watershed, which ultimately drains into the St. Lawrence River via the Lanaudière river network. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life, including fish species such as sturgeon and walleye. The plant's operations help maintain water quality in this important freshwater ecosystem.

The plant's treated effluent flows into the local tributaries of the Lanaudière region, which drain into the St. Lawrence River. The St. Lawrence River is a major waterway that supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. The river ultimately discharges into the Gulf of St. Lawrence, a critical marine environment. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality.
