Bassin 1 Wastewater Treatment Plant, Saint-Noël, Québec

Bassin 1 is a municipal wastewater treatment facility located on Rue Saint-Joseph O in Saint-Noël, a small community in the La Matapédia region of Bas-Saint-Laurent, Québec, Canada. The plant serves a population of 245 and is classified as a small-scale treatment facility. The plant provides secondary treatment, which is the standard level required under Canadian federal and provincial regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. Located within 10 km of the coast, the plant's treated effluent likely discharges into a local watercourse that eventually reaches the Gulf of St. Lawrence. This coastal proximity means the plant plays a role in protecting the sensitive marine ecosystem of the St. Lawrence Estuary, which supports diverse aquatic life including fish, crustaceans, and migratory birds.

The plant's discharge enters a local stream or river that drains into the Gulf of St. Lawrence, a major marine ecosystem in eastern Canada. The St. Lawrence Estuary is ecologically sensitive, supporting diverse aquatic life including fish, crustaceans, and migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads to this coastal environment.
