Station d epuration Wastewater Treatment Plant, Eastman, Quebec

Station d epuration is a municipal wastewater treatment plant located in Eastman, Quebec, Canada. It serves a small population of 234 residents, reflecting the rural character of the Memphrémagog region in the Estrie administrative region. The plant provides secondary treatment, which is the standard biological treatment 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. The treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River via the Richelieu River or other tributaries. The plant plays a key role in protecting the water quality of nearby water bodies and the broader St. Lawrence ecosystem.

The plant discharges into the local watershed within the Lake Memphrémagog basin, which flows northward via the Magog River into the St. Lawrence River. This region supports diverse aquatic life and is part of a larger drainage system that ultimately reaches the Atlantic Ocean. The plant's secondary treatment helps reduce nutrient loading and protects downstream water quality.
