Humber Treatment Plant - Rehabilitation of Digesters 1 to 6
Kenaidan's contract consisted of the removal and replacement of 4 concrete roofs and metal roofs on 6 digesters.
To prevent the base slabs from floating, a total of 1,800 rock anchors were added to all the slabs. Three new scrubber buildings, three new staircases, and one new electrical room were also constructed during the 3.5 years of phased construction, with no more than 2 digesters out of service at any one time. In addition, Kenaidan coordinated the removal and replacement of the existing gas and process piping in the digesters while maintaining the working operation of the plant.
