Usine d assainissement - Saint-Charles-de-Bellechasse Wastewater Treatment Plant, Quebec

Usine d assainissement is a municipal wastewater treatment plant located at 8 Rue Saint-Denis in Saint-Charles-de-Bellechasse, Quebec, Canada. The plant serves a population of 2,103 residents in this Chaudière-Appalaches community. It is currently operational and plays a key role in managing local wastewater. As a small-scale facility in Quebec, the plant is subject to provincial environmental regulations under the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC). For agglomerations of this size, secondary treatment is typically required to meet effluent quality standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the St. Lawrence River via the Chaudière River system. This river is a major tributary of the St. Lawrence, supporting diverse aquatic life and providing habitat for fish species such as Atlantic salmon and brook trout. The plant's operations help protect downstream water quality in this ecologically significant region.

The plant discharges into the Chaudière River basin, which flows northward into the St. Lawrence River near Quebec City. The St. Lawrence River is a major waterway that empties into the Gulf of St. Lawrence, a critical marine ecosystem supporting fisheries and migratory birds. The Chaudière River itself is a designated migratory corridor for fish and supports diverse aquatic habitats. Protecting water quality in this watershed is essential for maintaining the ecological health of the St. Lawrence estuary.
