Environmental context
Petersfield Lagoon discharges into the local watershed, which is part of the Lake Winnipeg basin. Lake Winnipeg is a large, shallow lake that supports diverse aquatic life and is a critical resource for the region. The plant's proximity to the coast means its effluent can influence the lake's water quality, particularly nutrient levels. Effective secondary treatment helps mitigate eutrophication risks in this sensitive freshwater ecosystem.
