Project progress update - August 2023
The tunnel boring machine (TBM) has finished it's 1km journey and broken through at the retrieval shaft!
About the project
Urban Utilities and our delivery partner, Fulton Hogan Utilities are building a new trunk sewer pipe which will run from Bowen Hills to Windsor.
The new pipe will cater for our growing community, with this catchment area expected to grow by around 37,000 people over the next 30 years.
With a diameter of 1.8 metres, the new one kilometre sewer will transport the wastewater from thousands of homes and businesses to the Luggage Point Resource Recovery Centre where it’s treated.
The site compound has been established near Perry Park at the corner of Folkestone Road and Edmondstone Street, Bowen Hills.
A vertical launch shaft has been constructed in the Perry Park site and the retrieval shaft is being constructed adjacent to the Airport Link northbound entry ramp and Lutwyche Road intersection to depths of approximately 14 metres below ground.
The TBM was installed on Monday, 13 March 2023 and reached the retrieval shaft on Wednesday, 9 August 2023.
The TBM was disassembled and demobilised from site later the same day.
The next stages of this project are sewer pipe completion works. This includes stripping the sewer pipe cables and hoses, grouting the external annulus, HDPE welding the pipes together and pressure testing.
Sewer pipe completion works are as follows:
- Monday to Saturday – 6am to 6pm
