Overview
Aerated Lagoon is a secondary treatment plant serving 544 people in Mishi-baawitigong / Little Grand Rapids, Manitoba, Canada. It discharges 244.40 cubic meters of treated wastewater into the local watershed.
Aerated Lagoon is a wastewater treatment facility located in Mishi-baawitigong / Little Grand Rapids, Manitoba, Canada. It serves a small community of 544 residents and operates under secondary treatment standards, which is typical for remote communities in the Canadian boreal forest region. The plant uses an aerated lagoon process to treat wastewater, a common method in northern Canada due to its low operational complexity and suitability for cold climates. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The treated effluent is released into the local watershed, which ultimately drains into the Winnipeg River system and Lake Winnipeg. This water body is ecologically significant, supporting diverse aquatic life and serving as a critical resource for downstream communities. The plant's operation helps protect water quality in this sensitive northern ecosystem.
Environmental context
The plant discharges into the local watershed, which flows into the Winnipeg River system and ultimately Lake Winnipeg, one of the largest freshwater lakes in the world. Lake Winnipeg is ecologically sensitive, supporting diverse fish populations and migratory birds. The region's boreal forest and wetlands provide natural filtration, but the plant's secondary treatment helps mitigate nutrient loading that could contribute to algal blooms in the lake.
Frequently asked questions

The plant serves a population of 544 residents in the community of Mishi-baawitigong / Little Grand Rapids.
The plant uses an aerated lagoon process, which is a secondary treatment method that uses oxygen to promote biological breakdown of organic matter. This is a common approach in northern Canadian communities.
The treated effluent is discharged into the local watershed, which drains into the Winnipeg River system and ultimately Lake Winnipeg.
In Canada, wastewater treatment is regulated under the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act. Secondary treatment is the minimum standard for most systems, and the plant's aerated lagoon process meets this requirement.
