STATION D ePURATION Wastewater Treatment Plant, Saint-Ludger, Québec

STATION D ePURATION is a municipal wastewater treatment facility located in Saint-Ludger, a small town in the Le Granit region of Québec, Canada. The plant serves a population of approximately 980 residents and operates under secondary treatment standards, which is typical for small communities in the province. As a secondary treatment plant, STATION D ePURATION uses biological processes to reduce organic matter and suspended solids before discharge. In Canada, wastewater treatment is regulated under provincial and federal guidelines, with Québec's Environment Quality Act overseeing permits and effluent standards. The treated effluent from the plant is discharged into a local water body, which ultimately drains into the Saint-François River watershed and then into the St. Lawrence River. This downstream connection highlights the plant's role in protecting the broader aquatic ecosystem, including the St. Lawrence River, which supports diverse fish populations and migratory birds.

The plant discharges into a local watercourse that flows into the Saint-François River, a tributary of the St. Lawrence River. The St. Lawrence River is a major ecological corridor in North America, supporting diverse aquatic life including fish species like Atlantic salmon and lake sturgeon. The watershed is also important for migratory waterfowl and provides drinking water for downstream communities.
