Lagoon Aerated Mechanical Wastewater Treatment Plant, Unorganized Division No. 21, Manitoba

Lagoon Aerated Mechanical is a municipal wastewater treatment plant located in Unorganized Division No. 21, Manitoba, Canada. It serves a small population of 659 residents and operates under secondary treatment standards, which is typical for small communities in the region. The plant uses an aerated lagoon system to treat wastewater, a common and cost-effective method for rural areas. As a secondary treatment facility, it meets the basic requirements for reducing organic matter and suspended solids before discharge. The plant is regulated under Manitoba's Environment Act and likely holds a provincial permit for its operations. The treated effluent is discharged into local waterways that eventually drain into Hudson Bay. This coastal discharge point is ecologically significant, as Hudson Bay supports diverse marine life and is an important habitat for fish and migratory birds. The plant's location within 10 km of the coast underscores the need for effective treatment to protect downstream ecosystems.

The plant discharges into a watershed that flows into Hudson Bay, a large inland sea with sensitive marine ecosystems. Hudson Bay supports species such as beluga whales, seals, and numerous fish and bird populations. The coastal environment is influenced by seasonal ice cover and freshwater inflows, making it vulnerable to nutrient loading and contaminants. Effective secondary treatment helps mitigate impacts on this ecologically important water body.
