Riverside Lagoon Wastewater Treatment Plant, Belmont, Manitoba

Riverside Lagoon is a municipal wastewater treatment facility located along Strathcona Centennial Trail in Belmont, within the Rural Municipality of Prairie Lakes, Manitoba, Canada. The plant serves a small population of 194 residents, reflecting its role in a rural community. The plant provides secondary treatment, which is the standard biological treatment process required under Canadian federal and provincial regulations for communities of this size. Secondary treatment effectively reduces organic matter and suspended solids before discharge, meeting typical environmental protection standards for small agglomerations. The treated effluent is discharged into the local watershed, which ultimately drains into the broader Lake Winnipeg basin. This region supports diverse aquatic life and is important for recreational and agricultural water use. The plant's operation helps protect downstream water quality in the Prairie Lakes area.

The plant discharges into the local watershed within the Lake Winnipeg drainage basin, one of the largest freshwater ecosystems in the world. The receiving waters support a variety of fish species and migratory birds. Protecting this watershed is critical for maintaining the ecological health of Lake Winnipeg, which faces challenges from nutrient loading and algal blooms.
