MDN usine de traitement des eaux usees Valcartier - Saint-Gabriel-de-Valcartier Wastewater Treatment Plant

MDN usine de traitement des eaux usees Valcartier is a municipal wastewater treatment plant located on Rue Dugas in Saint-Gabriel-de-Valcartier, Quebec, Canada. It serves a population of approximately 2,731 residents in the La Jacques-Cartier regional county municipality within the Capitale-Nationale administrative region. As a small-scale facility in Canada, the plant operates under provincial and federal regulations, including the Canadian Environmental Protection Act and Quebec's Regulation respecting wastewater treatment. For agglomerations of this size, secondary treatment is typically required to meet effluent quality standards. The plant has a designed capacity of 1.00 million liters per day. The plant discharges treated effluent into the local watershed, which drains into the Jacques-Cartier River, a tributary of the St. Lawrence River. The St. Lawrence River is a major waterway that flows into the Gulf of St. Lawrence and ultimately the Atlantic Ocean. The plant plays a role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens.

The plant's treated effluent enters the Jacques-Cartier River watershed, which flows into the St. Lawrence River. The St. Lawrence River is a critical freshwater resource supporting diverse aquatic life, including fish species such as Atlantic salmon and lake sturgeon. Downstream, the river discharges into the Gulf of St. Lawrence, an ecologically productive estuary. Protecting water quality in this system is important for maintaining biodiversity and supporting local communities that rely on the river for recreation and drinking water.
