Rehabilitation of Large Diameter Non-Circular Trunk Sewers - 2017

AECOM Canada Ltd.

This project included the rehabilitation of two large diameter trunk sewers within the City of Winnipeg’s combined sewer network. The Selkirk Avenue trunk, a 2030 x 1630 mm brick egg sewer, exhibited signs of severe deterioration. Active deterioration of the section required the emergency bracing and shotcrete stabilization prior to completion of the rehabilitation work. The Mission Trunk, a 2980 x 1980 mm concrete egg sewer located immediately upstream of the flood pumping station exhibited signs of severe sewer fabric loss. Both were successfully rehabilitated with Glass Reinforced Polymer panels, extending their useful service life for an additional 50 plus years.
