Lagoon Facultative Wastewater Treatment Plant - Makadewaagamijiwanoonsing/O'Hanly, Manitoba

Lagoon Facultative is a wastewater treatment plant located in the community of Makadewaagamijiwanoonsing/O'Hanly, Manitoba, Canada. It serves a small population of 377 residents, providing secondary treatment through a lagoon system. The plant is operational and discharges an average of 175.00 cubic meters of treated wastewater per day. As a secondary treatment facility, Lagoon Facultative meets the basic requirements for organic matter and suspended solids removal. In Canada, wastewater treatment is regulated under provincial and federal guidelines, with Manitoba's Environment Act governing discharge standards. For small communities like this, lagoon systems are common due to their cost-effectiveness and simplicity. The plant is located within 10 km of the coast, indicating its proximity to Lake Winnipeg or the Nelson River system. The treated effluent likely drains into a nearby water body that eventually reaches Hudson Bay. This coastal proximity necessitates careful management to protect downstream aquatic ecosystems from nutrient loading and other pollutants.

The plant discharges into a local water body that drains into the Lake Winnipeg basin, which ultimately flows into the Nelson River and Hudson Bay. Lake Winnipeg is ecologically sensitive due to eutrophication from nutrient inputs, making secondary treatment important for reducing organic and nutrient loads. The surrounding area includes boreal forest and wetlands that support diverse wildlife.
