Station d eau usee de St Gervais - Secondary Wastewater Treatment in Saint-Charles-de-Bellechasse, Quebec

Station d eau usee de St Gervais is a municipal wastewater treatment plant located on Route 279 in Saint-Charles-de-Bellechasse, Quebec, Canada. It serves a small population of 929 residents in the Chaudière-Appalaches region, operating under the regulatory framework of the Canadian Environmental Protection Act and provincial Quebec standards. The plant provides secondary treatment, which is the standard level for small communities in Canada. Secondary treatment uses biological processes to remove organic matter and suspended solids, ensuring effluent quality meets federal and provincial guidelines. The plant processes an average daily flow of 417.00 cubic meters, reflecting the scale of the local population. The treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River via the Chaudière River system. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life, including fish species such as Atlantic sturgeon and American eel. The plant's operations help protect downstream water quality in this sensitive estuarine environment.

The plant discharges into the Chaudière River watershed, which flows northward into the St. Lawrence River near Quebec City. The St. Lawrence River is a critical freshwater and estuarine ecosystem that supports migratory fish, waterfowl, and diverse aquatic habitats. The plant's secondary treatment reduces nutrient and organic loads, helping to mitigate eutrophication risks in the downstream river and estuary.
