Newdale Wastewater Lagoon - Secondary Treatment Plant in Manitoba, Canada

Newdale Wastewater Lagoon serves the small community of Newdale, located in the Municipality of Harrison Park, Manitoba, Canada. With a population served of 34, this facility is designed for a very small agglomeration, typical of rural prairie communities. The plant provides secondary treatment, which is the standard biological treatment stage required under Canadian wastewater regulations for communities of this size. The plant operates under provincial environmental protection laws administered by Manitoba's Department of Environment and Climate Change. The treated effluent is discharged into local waterways that ultimately drain into the Lake Winnipeg watershed, part of the larger Nelson River system flowing to Hudson Bay. Protecting water quality in this region is important for downstream aquatic ecosystems and recreational uses.

The plant discharges into the Assiniboine River basin, which flows into the Red River and eventually into Lake Winnipeg. Lake Winnipeg is a large, shallow lake prone to eutrophication from nutrient loading, making effective wastewater treatment critical for controlling phosphorus and nitrogen inputs that fuel algal blooms.
