Station d assainissement des eaux - Saint-Alexis-des-Monts, Quebec Wastewater Treatment Plant

Station d assainissement des eaux is a municipal wastewater treatment plant located in Saint-Alexis-des-Monts, Quebec, Canada. The plant serves a population of approximately 2,366 residents in this Mauricie region community. As an operational facility, it plays a key role in managing local wastewater and protecting public health. Given the small population served, the plant likely provides secondary treatment as a minimum, consistent with Canadian federal and provincial wastewater regulations. In Quebec, the Regulation respecting municipal wastewater treatment works (Q-2, r. 34.1) sets effluent standards for such facilities. Plants of this scale typically employ conventional activated sludge or lagoon systems. The plant discharges treated effluent into a local watercourse that ultimately drains into the Saint Lawrence River system. The Saint Lawrence River is a major ecological corridor supporting diverse aquatic life, including fish species such as walleye and yellow perch. Proper treatment helps maintain water quality in this sensitive watershed.

The plant discharges into a local tributary of the Saint Lawrence River, which flows into the Gulf of Saint Lawrence and eventually the Atlantic Ocean. The Saint Lawrence River supports diverse aquatic ecosystems, including fish populations and migratory birds. The watershed is ecologically sensitive, and effective wastewater treatment is essential to prevent nutrient loading and protect downstream habitats.
