ETANG DE LOUISEVILLE Wastewater Treatment Plant, Louiseville, Quebec

ETANG DE LOUISEVILLE is a municipal wastewater treatment plant located in Louiseville, Quebec, Canada. It serves a population of approximately 7,030 residents in the Mauricie region. The plant is operational and plays a key role in managing wastewater for this community. As a small agglomeration in Quebec, the plant is subject to provincial wastewater regulations under the Quebec Environment Quality Act. These regulations require appropriate treatment to protect receiving waters. Plants of this scale typically employ secondary treatment or equivalent technologies to meet effluent standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the St. Lawrence River via the Lac Saint-Pierre area. This region is ecologically significant, supporting diverse aquatic life and serving as an important migratory corridor for fish and birds. Proper treatment helps maintain water quality in this sensitive ecosystem.

The plant's treated effluent flows into the local water system, which drains into the St. Lawrence River near Lac Saint-Pierre. This area is a biologically rich floodplain that supports diverse fish species, waterfowl, and aquatic vegetation. The St. Lawrence River eventually reaches the Gulf of St. Lawrence and the Atlantic Ocean, making effective wastewater treatment critical for downstream water quality and ecosystem health.
