Pekuakamiulnutsh Takuhikan etang aere Wastewater Treatment Plant, Mashteuiatsh, Quebec

Pekuakamiulnutsh Takuhikan etang aere is a wastewater treatment plant located at 247 Rue Matshetshu in Mashteuiatsh, Quebec, Canada. The plant serves the community of Mashteuiatsh, which is part of the Saguenay-Lac-Saint-Jean region, and handles wastewater for a population of about 2,405 residents. As a Canadian facility, the plant operates under the federal Wastewater Systems Effluent Regulations (WSER) and provincial Quebec environmental regulations. For a small community of this size, secondary treatment is typically required to meet effluent quality standards. The plant has a designed capacity of 1.00 million liters per day, indicating it is sized appropriately for the local population. The treated effluent is discharged into the local watershed, which ultimately drains into Lac Saint-Jean, a large freshwater lake in Quebec. Lac Saint-Jean is part of the Saguenay River system, which flows into the St. Lawrence River and eventually the Atlantic Ocean. The plant plays a key role in protecting the water quality of Lac Saint-Jean and downstream ecosystems.

The plant discharges into the watershed of Lac Saint-Jean, a large lake in the Saguenay-Lac-Saint-Jean region. Lac Saint-Jean drains via the Saguenay River into the St. Lawrence River, a major waterway that supports diverse aquatic life and is an important migratory corridor for fish such as Atlantic salmon. The lake itself is ecologically sensitive, supporting recreational fisheries and local biodiversity. Proper wastewater treatment is essential to prevent nutrient loading and maintain water quality in this freshwater system.
