Southshore WRF - Secondary Wastewater Treatment in Municipal District of Lesser Slave River, Alberta

Southshore WRF is a wastewater treatment facility located in the Municipal District of Lesser Slave River, Alberta, Canada. It serves a small population of 59 residents, reflecting its role in a rural community. The plant is operational and provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. As a secondary treatment plant, Southshore WRF meets the basic requirements under Canadian provincial regulations for wastewater treatment in rural areas. The plant's discharge volume of 100 cubic meters per day indicates it is sized appropriately for the small population served. Canadian wastewater facilities are typically regulated by provincial authorities, with Alberta Environment and Parks overseeing permits and compliance. The treated effluent from Southshore WRF is discharged into the local watershed, which ultimately drains into Lesser Slave Lake, a large freshwater lake in northern Alberta. The lake supports diverse aquatic life and is an important recreational and ecological resource. The plant's proximity to the lake (within 10 km of the coast) means its discharge must be carefully managed to protect water quality in this sensitive environment.

Southshore WRF discharges treated wastewater into the Lesser Slave Lake watershed. Lesser Slave Lake is a large, shallow lake that drains via the Lesser Slave River into the Athabasca River, which eventually flows into the Arctic Ocean via the Mackenzie River system. The lake supports a variety of fish species, including walleye and northern pike, and is an important stopover for migratory birds. Protecting water quality in this lake is critical for maintaining its ecological health and recreational value.
