Saint Denis de Brompton Village Wastewater Treatment Plant, Quebec

The Saint Denis de Brompton village wastewater treatment plant is located in Saint-Denis-de-Brompton, Quebec, Canada, serving a small community of 334 residents. The plant operates under the regulatory framework of the Canadian Environmental Protection Act and provincial Quebec regulations, which require secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard level for small communities in Canada. As an inland facility, it is not within 10 km of the coast, reducing direct marine impact. The treated effluent flows into local waterways within the St. Lawrence River basin, ultimately reaching the St. Lawrence River and the Atlantic Ocean. The plant's operations help protect the ecological health of the surrounding watershed, supporting aquatic life and water quality in the region.

The plant discharges into local streams that are part of the St. Lawrence River drainage basin. The St. Lawrence River is a major waterway that flows into the Gulf of St. Lawrence and the Atlantic Ocean. The watershed supports diverse aquatic ecosystems, including fish species such as Atlantic salmon and brook trout, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality.
