The microtunnel boring machine (MTBM) constructing Urban Utilities’ Breakfast Creek Trunk Sewer Main Upgrade in Brisbane has broken through.
Microtunnelling contractor Rob Carr, on behalf of principal contractor Fulton Hogan, used a 29t Herrenknecht MTBM to excavate the new 1km long wastewater pipe running under the heart of the city.
The Urban Utilities project is part of a major infrastructure upgrade to cater for population growth in the Brisbane’s north, which is expected to increase by 37,000 over the next 30 years.
The utility said the use of trenchless technology saved “considerable time” on these essential upgrades and “drastically reduced” the impact to the community.
A trunk main will now be installed inside the tunnel and be connected to the existing S1 sewer so it can start transferring wastewater within the utility’s 19000 km network.
