Wastewater Plant Replacement

pre-construction

The project will replace an aging wastewater treatment facility with a new mechanical treatment plant in the Naotkamegwanning First Nation, Ontario. The scope will involve the design and construction of a new wastewater facility that encompasses primary, secondary and tertiary treatment with key components including headworks, primary clarifiers, a rotating biological contactor, ultraviolet disinfection, aerated sludge digestion, sludge dewatering, a new effluent outfall and diffuser, and ventilation upgrades. A back-up generator will be added to support the plant and existing lift station. The project will more than double capacity as the current facility is operating at 80% above its design; improve service reliability by resolving frequent failures of the rotating biological contactor and by providing back-up power; and address health and safety concerns by ensuring proper ventilation to reduce the potential for a hazardous gas build-up.
