Two years since it began its maiden voyage under Brisbane’s south side, “Sewey”, the tunnel borer, has made it to the finish line.
Weighing the equivalent of six elephants, Sewey made the breakthrough into Settlers Street Park at Carindale, marking the end of tunnelling for the Bulimba Creek Sewer Upgrade.
Queensland Urban Utilities Project Manager, Will Campbell, said it was a significant milestone for the $55 million project.
“After months of chewing her way through hard rock, Sewey emerged without the colourful design created by Easts Mt Gravatt Junior Rugby League Club member Caitlin Gamble,” he said.
“Most importantly though, she completed her mission.
“The new trunk sewer from Carindale to Mansfield will meet the needs of future growth in south-east Brisbane until 2050 and cater for an additional 271,000 people.”
The upgrade has involved installing 4.25km of new sewer main with the majority using modern trenchless (tunnelling) technology.
“As it’s a gravity trunk sewer, we’ve been working at depths of up to 50 metres below ground, so using modern technology was paramount to reduce the impact on the wider community and environment,” said Mr Campbell.
“We thank residents for their patience while we’ve constructed this essential infrastructure, which enhances the liveability of our communities.”
With tunnelling now complete, work is expected to be finished by March 2019, subject to weather and site conditions.
The new sewer will carry waste water to the Gibson Island Sewage Treatment Plant.
It will be the second largest sewer pipe in the Queensland Urban Utilities network, after the S1 Main Sewer, which runs from Toowong to Eagle Farm.
