etangs aeres Saint Ephrem Wastewater Treatment Plant, Saint-Éphrem-de-Beauce, Québec

The etangs aeres Saint Ephrem wastewater treatment plant is located in Saint-Éphrem-de-Beauce, a municipality in the Beauce-Sartigan region of Québec, Canada. The plant serves a population of approximately 2,157 residents and operates as a secondary treatment facility, which is standard for small communities in the province. As a secondary treatment plant, it uses biological processes to reduce organic matter and suspended solids before discharge. The plant's daily discharge volume is 970 m³, and it operates under Québec's environmental regulations, which align with the Canada-wide standards for wastewater systems. For communities of this size, secondary treatment is the expected minimum to protect receiving waters. The treated effluent is discharged into local waterways that drain into the Chaudière River, which flows northward to the St. Lawrence River. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life and migratory fish species. The plant's operations help maintain water quality in this sensitive watershed.

The plant discharges into a tributary of the Chaudière River, which flows into the St. Lawrence River, one of North America's largest and most ecologically significant waterways. The St. Lawrence River supports a wide range of aquatic species, including several fish populations that rely on clean water for spawning and migration. The region's watershed is also important for local agriculture and recreation, making effective wastewater treatment essential for preserving downstream water quality.
