Millet Lagoon Wastewater Treatment Plant, County of Wetaskiwin, Alberta

Millet Lagoon is a municipal wastewater treatment facility located on Range Road 231A in the County of Wetaskiwin, Alberta, Canada. The plant serves a small population of 236 residents, reflecting its role in a rural agricultural community within the province's interior. The plant provides secondary treatment, which is the standard biological treatment process required under Canadian federal and provincial regulations for communities of this size. Alberta's Environmental Protection and Enhancement Act governs wastewater discharges, ensuring that treated effluent meets water quality standards to protect receiving environments. The treated wastewater is discharged into local watercourses that ultimately drain into the North Saskatchewan River basin, part of the larger Hudson Bay drainage system. The surrounding area features mixed farmland and wetlands, and the plant's operations help maintain water quality in these sensitive prairie ecosystems.

The plant discharges into local streams that flow into the North Saskatchewan River, which eventually reaches Lake Winnipeg and Hudson Bay. The watershed supports diverse aquatic life, including fish species such as walleye and northern pike, and provides habitat for migratory waterfowl. Maintaining low nutrient and pathogen levels in the effluent is critical to prevent eutrophication in downstream water bodies.
