Station epuration St Gedeon - Wastewater Treatment Plant in Saint-Gédéon-de-Beauce, Québec

Station epuration St Gedeon is a municipal wastewater treatment plant located in Saint-Gédéon-de-Beauce, Québec, Canada. The facility serves a population of approximately 2,038 residents in the Beauce-Sartigan region of the Chaudière-Appalaches administrative area. As a small-scale treatment plant, it plays a key role in managing local domestic wastewater. The plant operates under Canada's Wastewater Systems Effluent Regulations (WSER) and Québec's provincial environmental standards. For small agglomerations like this, treatment typically involves primary or secondary processes to meet effluent quality requirements. The facility is operational and contributes to protecting downstream water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Chaudière River and then to the St. Lawrence River. This connection to a major waterway underscores the plant's importance in safeguarding aquatic ecosystems and downstream communities.

The plant discharges into the Chaudière River basin, which flows northward into the St. Lawrence River, a major waterway supporting diverse aquatic life and migratory fish species. The watershed is ecologically sensitive, with seasonal variations in flow and temperature. Proper treatment helps prevent nutrient loading and contamination that could affect downstream habitats and water uses.
