Mannville Lagoon Wastewater Treatment Plant, Village of Mannville, Alberta

Mannville Lagoon is a wastewater treatment facility located in the Village of Mannville, Alberta, Canada. The plant serves a small population of 539 residents, providing secondary treatment to meet provincial and federal environmental standards. As a lagoon-based system, it relies on natural biological processes to treat wastewater before discharge. The plant operates under Alberta's Environmental Protection and Enhancement Act, which governs wastewater discharges in the province. Secondary treatment is appropriate for this small community, ensuring that organic matter and suspended solids are reduced to acceptable levels. The facility's discharge volume of 242.00 reflects the modest scale of the community it serves. The treated effluent from Mannville Lagoon is discharged into local watercourses that ultimately drain into the North Saskatchewan River basin. This river system flows eastward through Alberta and into Saskatchewan, supporting diverse aquatic life and providing water for downstream communities. The plant's location inland, far from coastal areas, reduces direct marine impact but requires careful management to protect freshwater ecosystems.

Mannville Lagoon discharges into local water bodies that are part of the North Saskatchewan River watershed. This river flows through central Alberta and into Saskatchewan, eventually reaching Lake Winnipeg via the Saskatchewan River system. The watershed supports a variety of fish species, including walleye and northern pike, and provides habitat for migratory birds. The plant's secondary treatment helps protect these downstream ecosystems from excessive nutrient loading and organic pollution.
