Queensland Urban Utilities is committed to excellence in water and sewerage services that meet the evolving needs of our customers and enhance our communities. As part of this commitment, we are constructing a cross-river water pipeline from Murarrie to Pinkenba, which will connect two water supply zones - the Bartleys Hill reservoir in Ascot and the Wellers Hill reservoir in Murarrie.
Project update - November 2017
Construction of the $20M Murarrie-Pinkenba Cross River Water Pipeline is well underway. Once finished, the project will help cater for future demand and ensure security of water supply to Pinkenba, Eagle Farm and Murarrie. It will also make the provision of water supply more flexible and minimise customer impacts in the event of a water outage, for example, during extreme weather.
- We have installed the water pipe over the creek culverts on Holt Street using open trenching.
- Open trench installation of about 1060 metres of new water pipeline along Holt Street is complete.
- We have installed valve chambers on Kingsford Smith Drive that will enable water flow control for maintenance and supply purposes.
- Open trench construction of about 600 of 850 metres of new water pipeline along Queensport Road North is complete.
- Auger boring (drilling) to install the water pipe under the stormwater culverts on Queensport Road North is complete.
Drilling under the Brisbane River is complete. The 1.1km of water pipeline was completed using horizontal directional drilling (HDD). This form of trenchless technology has three stages as outlined below.
Starting at the entry point off Paringa Road, Murarrie, the pilot hole was drilled along the alignment using a GPS directional guidance system to navigate the drill head position. It bored 10 metres below the riverbed until it reached the southern bank and then rose to the exit point in Pinkenba.
A 500 tonne rig was based on the Pinkenba side of the river and systematically enlarge the pilot hole. Multiple reams were carried out until the diameter was large enough to install the 800mm trunk water main.
The drilled hole was cleaned and prepared for the pipeline installation. The high density polyethylene (HDPE) pipe was laid out in a single ‘string’ along the rail siding at Murarrie and placed on rollers. The pipe was then pulled back towards the entry point in Pinkenba until the pipeline was installed.
The above video shows the pipe pullback stage of horizontal directional drilling on this project.
- Connecting the new water main to the existing water network on Kingsford Smith Drive. You will receive further information about this work prior to construction.
- Road resurfacing of construction damaged areas will be complete once the pipe has been tested and all work along Holt Street is complete.
- Connecting the new water pipeline to the existing network in the Transurban land at the northern end of Queensport Road North. You will receive further information about this work prior to construction.
- Following the completion of the river crossing, a permanent switchboard will be installed and secured at the current construction site. You will receive further information about this work prior to construction.
- Road resurfacing of construction damaged areas will be complete once the pipe has been tested and all work along Queensport Road North is complete.
The project team is committed to minimising the construction impacts on our customers. We will keep the community informed and provide regular updates to directly impacted customers. We will also work closely with our contractor to ensure every effort is made to keep disturbances to a minimum.
