Large Diameter Sliplining Rehabilitation of the Groat Road Storm Trunk
The Groat Road Storm Trunk Sewer services over 1,800 hectares of the north-west area of the City of Edmonton and is composed of 1,800 m of 1,727 mm, and 2,200 m of 2,337 mm diameter plate corrugated metal pipe (CMP). The trunk ranges between 7 and 17 m in depth, and includes 16 manholes, 7 drop structures, numerous laterals, and a large concrete combination chamber. This chamber links the 1,727 mm upstream to the 2,337 mm diameter downstream pipe section. Constructed in the mid 1950s, this trunk had experienced significant deterioration resulting in loss of invert, corrosion, and ovaling at numerous locations along its length. In 2018, Shanghai Construction Group (Canada) Corporation (SCG) was awarded the contract for the rehabilitation of the Groat Road Storm Trunk. SCG’s approach involved sliplining the CMP with fiberglass reinforced polymer (FRP) pipe and grouting the annular space and voids around the existing pipe. Drop structures would be replaced with new manholes, and existing chambers were rehabilitated with centrifugally cast concrete product. This paper discusses the challenges and lessons learned by the contractors engineering and construction team. It also reviews the design of the sliplining rehabilitation program and the delivery of this complex and challenging project.
