Queensland Urban Utilities reaches milestone on cross-river pipeline
Queensland Urban Utilities has reached another milestone in the construction of its AU$20 million cross-river pipeline, achieving pipe pull through on 15 November 2017.
In a spectacular feat of engineering, more than 1 km of pipe was stretched along a disused rail line at Murarrie before being fed more than 20 m underground, beneath the river bed from Murarrie to Pinkenba in Brisbane.
The process began in the early hours, and took almost 11 hours to complete with the pipe successfully emerging near Holt St at Pinkenba.
The cross-river pipeline is part of a range of Queensland Urban Utilities’ major water and sewerage projects worth almost AU$175 million that are using Trenchless Technology.
Queensland Urban Utilities Spokesperson Sally Prosser said the pipe was first suspended by cranes and rollers along the railway line at Murarrie.
“Using advanced Trenchless Technology, we already bored a path for the new pipeline under the river. This step involved pulling the pipe through,” said Ms Prosser.
“It was quite an impressive sight, as the pipe is more than 1 km long and 800 mm in diameter.”
The project also includes 1.2 km of new water pipe along Holt Street at Pinkenba and around 850 m of new pipeline along Queensport Road North at Murarrie.
The works will cater for future demand in suburbs such as Hamilton and Eagle Farm, as well as the thriving Australia TradeCoast Industrial Precinct, which includes an airport.
Ms Prosser said it is the biggest water infrastructure project since Queensland Urban Utilities was formed in 2010.
“Water is an essential service that more than 1.4 million people in our region rely on every day, but it’s largely hidden underground,” she said.
“Projects like this demonstrate that a lot goes on behind the scenes to deliver fresh, clean drinking water to your tap.”
