Reston Lagoon Wastewater Treatment Plant, Reston, Manitoba

Reston Lagoon is a municipal wastewater treatment facility located in Reston, within the Rural Municipality of Pipestone, Manitoba, Canada. The plant serves a small population of 486 residents, reflecting its role in a rural community. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Canada's federal and provincial wastewater regulations, which require secondary treatment for communities of this size. The plant's design as a lagoon system is typical for small Canadian communities, offering cost-effective treatment with low energy consumption. The discharge volume of 218.00 cubic meters per day indicates a modest flow consistent with the population served. The treated effluent from Reston Lagoon is released into the local watershed, which drains into the Pipestone Creek and eventually the Souris River system. This river flows south into the United States, joining the Assiniboine River and ultimately the Red River, which empties into Lake Winnipeg. The plant plays a key role in protecting downstream water quality in this transboundary basin.

Reston Lagoon discharges into the Pipestone Creek watershed, part of the Souris River basin that flows into the Assiniboine River and ultimately Lake Winnipeg. This region is characterized by prairie agricultural land, and the plant helps mitigate nutrient loading that could contribute to algal blooms in downstream lakes. The local aquatic ecosystem supports species such as walleye and northern pike, making water quality management critical for both ecological health and recreational fishing.
