Overview
The Lagoon Facultative plant in Berens River, Manitoba, Canada, serves a small community of 674 people with secondary treatment. Its treated wastewater discharges near the coast of Lake Winnipeg.
The Lagoon Facultative wastewater treatment plant is located in the community of Mememwi-ziibiing / Berens River, within the Unorganized Division No. 19 in Manitoba, Canada. This facility serves a small population of 674 residents and operates under secondary treatment standards, which is typical for small, remote communities in the region. As a facultative lagoon system, the plant relies on natural biological processes to treat wastewater, including aerobic and anaerobic zones. The plant's operational status is active, and it discharges approximately 398 cubic meters of treated effluent per day. Given its coastal proximity, the plant's performance is subject to provincial environmental regulations to protect receiving waters. The plant discharges into the Berens River, which flows into Lake Winnipeg, a large and ecologically important lake in Manitoba. Lake Winnipeg is known for its significant algal blooms driven by nutrient loading, making effective wastewater treatment crucial for downstream water quality. The plant's secondary treatment helps reduce organic pollutants and nutrients before discharge.
Environmental context
The plant discharges into the Berens River, which flows into the northeastern basin of Lake Winnipeg. Lake Winnipeg is the 10th largest freshwater lake in the world and supports a major fishery, but it has experienced severe eutrophication due to nutrient inputs from agricultural runoff and wastewater. The plant's secondary treatment helps mitigate nutrient loading, though the lake remains sensitive to additional phosphorus and nitrogen. The surrounding boreal forest watershed provides natural filtration, but the coastal location increases the risk of nutrient transport to the lake.
Frequently asked questions
The plant is located in Mememwi-ziibiing / Berens River, within the Unorganized Division No. 19 in Manitoba, Canada, near the eastern shore of Lake Winnipeg.
The plant serves a small community of 674 people, typical of remote northern settlements in Manitoba.
The plant uses a facultative lagoon system for secondary treatment and discharges treated effluent into the Berens River, which flows into Lake Winnipeg.
In Canada, wastewater treatment is regulated by provincial authorities. In Manitoba, the plant operates under the Manitoba Environment Act and the Water Protection Act, which set effluent quality standards for discharges into sensitive water bodies like Lake Winnipeg.
For small communities like Berens River, facultative lagoons are common due to low cost and simple operation. These systems provide secondary treatment through natural biological processes, which is adequate for reducing organic matter and pathogens.
