Utility using trenchless to construct AU$175 million of infrastructure

The works include the construction of a new water pipeline underneath the Brisbane River from Murrarie to Pinkenba, the building of a new trunk sewer – including a 48 m deep access shaft for a tunnel boring machine – from Mansfield to Carindale, and tunnelling under the Brisbane River from Kenmore to Jindalee for new water and sewer pipelines.

The utility is also using trenchless relining to rehabilitate Brisbane’s oldest and largest sewer pipe, the S1 Main Sewer.

“We’ve always got major capital works underway, but this is the most construction we’ve seen at once in our organisation’s history,” said Queensland Urban Utilities spokesperson Sally Prosser.

“Across three major projects, more than 4.2 km of new water pipe is being laid and more than 6.8 km of new sewers, building on our existing network of more than 18,000 km of pipe.

“A fourth project involves relining 5.7 km of Brisbane’s S1 Main Sewer, which is 100 years old and buried eight storeys under busy Kingsford Smith Drive.

“These works increase the resilience and reliability of our water and sewerage network and ensure we’re catering for South East Queensland’s growing population.”

Ms Prosser said water and sewerage is an essential service that the utility’s more 1.4 million customers relied on every day.

“With all the cranes across the city, it’s easy to see the skyline changing right before your eyes. That’s not the case for the water and sewerage network,” she said.

“It’s a hidden service, but as projects like these demonstrate, a lot goes on behind the scenes to deliver fresh, clean drinking water to your tap and allow you to flush and forget.”
