Nahanni Butte Design-Build Water Treatment Plant
Nahanni Butte, NT
Project Overview
This design-build water treatment plant was constructed in 2019-2020 for the residents of Nahanni Butte, NT. Northern Industrial Construction was contracted to design and retrofit the existing water treatment plant which had extensive damage to the existing piping, pumps and equipment. The scope of work involved upgrades and redesign of the main process systems including raw water, pre-oxidation, pressure filtration, softeners, chemical dosing, treated water storage and truck fill. The water treatment plant control system was redesigned and updated to optimize plant operation. Upon construction completion, start up activities were completed such that NIC provided the client with a “turn-key” facility.
