Swan River Lagoon Wastewater Treatment Plant, Kinuso, Alberta

Swan River Lagoon is a wastewater treatment facility located in Kinuso, Big Lakes County, Alberta, Canada. It serves a small population of 356 residents, providing secondary treatment for municipal wastewater. The plant is situated in a rural area near the western edge of the province, close to the shores of Lesser Slave Lake. As a secondary treatment plant, Swan River Lagoon meets the standard level of treatment required for small communities in Alberta. The province's Environmental Protection and Enhancement Act governs wastewater discharges, with permits issued by Alberta Environment and Parks. For a facility of this scale, lagoon-based treatment systems are common, utilizing natural processes to reduce organic matter and pathogens before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into Lesser Slave Lake, a large lake in northern Alberta. The lake is part of the Slave River basin, flowing northward through the Mackenzie River system into the Arctic Ocean. The area supports diverse aquatic life and is an important habitat for fish and waterfowl.

The plant discharges into the watershed of Lesser Slave Lake, a large lake in northern Alberta that drains via the Lesser Slave River into the Athabasca River, then the Slave River, and finally the Mackenzie River to the Arctic Ocean. The lake supports a diverse ecosystem, including fish species such as walleye and northern pike, and provides critical habitat for migratory birds. The region's cold climate and seasonal ice cover influence treatment performance and receiving water quality.
