Lagoon Wastewater Treatment Plant, Mackenzie, British Columbia

The lagoon wastewater treatment plant is located in Mackenzie, British Columbia, Canada, serving a population of about 1,273 residents. The facility is situated inland near the Parsnip West Forest Service Road and operates as part of the municipal wastewater infrastructure for the community. As a lagoon-based system, the plant provides natural treatment through settling and biological processes. Canadian wastewater facilities of this scale typically operate under provincial regulations that require secondary treatment or equivalent performance. The plant's designed capacity is 1.00 million liters per day, indicating it is sized for the local population. The treated effluent is discharged into the local watershed, which ultimately drains into the Parsnip River and then into the Peace River system. This river network flows into the Mackenzie River basin, eventually reaching the Arctic Ocean. The plant plays a key role in protecting the water quality of these downstream water bodies and supporting aquatic life in the region.

The plant discharges into the Parsnip River watershed, which flows into the Peace River and then the Mackenzie River system, ultimately reaching the Arctic Ocean. This remote boreal region supports diverse fish populations, including Arctic grayling and bull trout, and provides important habitat for migratory waterfowl. The lagoon treatment helps reduce nutrient and pathogen loads to protect downstream aquatic ecosystems.
