Teulon Wastewater Treatment Lagoon - Rural Manitoba Secondary Treatment Facility

Teulon Wastewater Treatment Lagoon is a small-scale municipal facility located on Road 14E in the Rural Municipality of Rockwood, Manitoba, Canada. Serving a population of 42, it is designed for low-density rural communities and operates under provincial environmental regulations. The plant provides secondary treatment, which is the standard biological treatment stage required for most Canadian wastewater facilities. The plant's discharge volume of 721.00 cubic meters indicates a modest flow typical of small lagoon systems. Canadian wastewater treatment is governed by the Canada-wide Strategy for the Management of Municipal Wastewater Effluent, which sets national performance standards for effluent quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Lake Winnipeg basin. Lake Winnipeg is a large, ecologically sensitive lake that experiences eutrophication challenges due to nutrient loading. The plant's secondary treatment helps reduce organic pollutants and nutrients, contributing to the protection of downstream water quality.

The plant discharges into the local watershed within the Lake Winnipeg drainage basin. Lake Winnipeg is the 10th largest freshwater lake in the world and is highly sensitive to nutrient pollution, which can cause harmful algal blooms. The facility's secondary treatment helps mitigate nutrient loading, supporting the ecological health of the lake and its tributaries.
