Lagoon Big River Wastewater Treatment Plant, Big River No. 555, Saskatchewan

Lagoon Big River is a wastewater treatment facility located in the rural municipality of Big River No. 555, Saskatchewan, Canada. The plant serves a small population of 58 residents, reflecting its role in a sparsely populated area. It operates under the regulatory framework of Saskatchewan's Environmental Management and Protection Act, which governs wastewater discharges in the province. The plant provides secondary treatment, a standard level for small communities in Canada. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from Lagoon Big River likely enters a local watercourse that drains into the Saskatchewan River system, eventually reaching Hudson Bay. The surrounding area is characterized by boreal forest and numerous small lakes, making proper wastewater management important for protecting local aquatic ecosystems and downstream water quality.

The plant's discharge likely flows into a small stream or lake within the Saskatchewan River basin, which ultimately drains into Hudson Bay via the Nelson River. The region's boreal forest and numerous water bodies support diverse aquatic life, including fish species such as walleye and northern pike. Proper treatment helps prevent nutrient loading and maintains water quality in these sensitive northern ecosystems.
