Woolloongabba sewer upgrade Brisbane

Project Owner: Queensland Urban Utilities (QUU)
Project Head Contractor: JOHN HOLLAND GROUP Pty Ltd (JHG)
Project: WOOLLOONGABBA Trunk Sewer Upgrade, Stages 2 and 3

A new sewer line has now been installed in the South Kangaroo Point which will work in parallel with the existing system to significantly increase the sewer capacity. Installation of the new sewer line took place using small diameter tunnel boring machines rather than open trenching, to reduce the impact on local roads.

The Woolloongabba Sewer at the time was the largest GRP jacking pipe project in Australian history, with over 5km of pipe installed under some of Brisbane’s busiest streets. Several individual drives were over 400 metres in length, including curved drives. Global Pipe remained on site for the initial deliveries and provided an on-site assessment of pipe with the application engineer, providing replacement pipe in under two weeks’ time and follow-up visits with project engineers. A crew was supplied to repair any ‘separation steps’ that occurred during jacking.

Global Pipe working with the WTSU project team, JHG, QUU and GHD consultants, delivered a successful result utilising existing technologies and pushing the boundaries of trenchless technology to overcome multiple issues which arise when working in a busy urban environment. The project completed five months ahead of schedule.
