Site de traitement des eaux usees du secteur de Shawinigan Sud is a municipal wastewater treatment plant located in the Shawinigan-Sud district of Shawinigan, Quebec, Canada. The plant serves a population of about 14,536 and is situated in the Mauricie region, an area characterized by the St. Lawrence River valley and mixed urban and rural land use. As a Canadian facility, the plant operates under provincial and federal regulations, including the Quebec Environment Quality Act and the Canadian Environmental Protection Act. The plant's operational status indicates it is actively managing wastewater from the local area. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the St. Lawrence River. The St. Lawrence River is a major ecological corridor supporting diverse aquatic life, including fish species such as Atlantic sturgeon and lake sturgeon, and is an important migratory route for birds. The plant's operations contribute to protecting the water quality of this vital river system.

The plant discharges into the St. Lawrence River watershed, which flows into the Gulf of St. Lawrence and eventually the Atlantic Ocean. The St. Lawrence River is a critical freshwater resource and supports a diverse ecosystem, including fish populations and migratory birds. The plant's treatment helps reduce nutrient and pollutant loads, protecting downstream aquatic habitats and the river's ecological integrity.
