etang de ville de desbiens Wastewater Treatment Plant, Chambord, Quebec

The etang de ville de desbiens is a municipal wastewater treatment plant serving the community of Chambord in the Saguenay-Lac-Saint-Jean region of Quebec, Canada. The plant provides secondary treatment for a population of approximately 1,169 residents, reflecting its role as a small-scale facility in a rural setting. As a secondary treatment plant, it meets the basic standards required under Canadian wastewater regulations, which mandate secondary treatment for most municipal facilities to reduce organic matter and suspended solids. The plant's proximity to the coast (within 10 km) means its discharge ultimately reaches the Lac Saint-Jean watershed, which drains into the Saguenay River and eventually the St. Lawrence Estuary. This coastal location underscores the importance of effective treatment to protect sensitive aquatic ecosystems in the region.

The plant discharges into the Lac Saint-Jean basin, which feeds the Saguenay River and flows into the St. Lawrence Estuary, a critical habitat for marine life including beluga whales and migratory fish. The region's cold climate and seasonal variations influence treatment efficiency and receiving water quality. Protecting this downstream environment requires consistent secondary treatment to minimize nutrient loading and pathogen release.
