Landmark Lagoon Wastewater Treatment Plant, Rural Municipality of Taché, Manitoba

Landmark Lagoon is a wastewater treatment facility located in the Rural Municipality of Taché, Manitoba, Canada. The plant provides secondary treatment to a population of about 1,085 residents, serving the local community's sanitation needs. As a secondary treatment plant, Landmark Lagoon meets the standard requirements for biological treatment of organic matter. In Canada, wastewater treatment is regulated under provincial and federal guidelines, with Manitoba's Environment Act and the Canadian Environmental Protection Act governing discharge quality. For small communities like this, lagoon systems are common and effective. The treated effluent from Landmark Lagoon is discharged into local watercourses that eventually drain into the Red River and ultimately into Lake Winnipeg. Lake Winnipeg is a large, ecologically sensitive lake that experiences eutrophication challenges, making nutrient removal from wastewater important for downstream water quality.

Landmark Lagoon discharges into local streams that flow into the Red River, which drains north into Lake Winnipeg. Lake Winnipeg is a large, shallow lake that supports diverse aquatic life and is a critical resource for recreation, fisheries, and tourism. The lake is prone to algal blooms due to nutrient loading, so effective secondary treatment helps reduce the plant's contribution to eutrophication.
