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 - August 2017
Construction of the $20M Murarrie-Pinkenba Cross River Water Pipeline is well underway with over 1600 metres of open trench pipe installation complete so far. We will shortly start constructing the pipeline under the Brisbane River using horizontal directional drilling.
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.
- Open trench installation of about 1060 metres of new water pipeline along Holt Street is now complete.
- We are currently installing valve chambers on Kingsford Smith Drive that will enable water flow control for maintenance and supply purposes.
- Open trench construction of about 600 metres of new water pipeline along Queensport Road North is now complete.
- Auger boring (drilling) to install the water pipe under the stormwater culverts on Queensport Road North is complete.

- Installing the water pipe over
stormwater culverts on Holt Street using open trenching.
- Establishing a horizontal
directional drill rig launch site at the river end of Holt Street.
- Road resurfacing of construction
damaged areas will be complete once the pipe has been tested and all work
along Holt Street is complete.
- Installing a horizontal
directional drill rig at the Queensport Road construction site.
- 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 and transformer 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 Brisbane River is scheduled to start in early-August 2017 and will
take about three months to complete. Work hours for site set up will
be Monday to Friday from 6.30am to 6.30pm. Once the drill rigs are set up,
drilling will be done 24/7 until the 1.1km river crossing is complete.
Starting at the
entry point off Paringa Road, Murarrie, the pilot hole will be drilled along
the alignment using a GPS directional guidance system to navigate the drill
head position. It will bore 10 metres below the riverbed until it reaches the
southern bank and then rises to the exit point in Pinkenba. Stage one is
expected to start in early-August 2017 and take about one week to complete,
weather and ground conditions permitting.
A 250 tonne rig
will be based on the Pinkenba side of the river and used to
systematically enlarge the pilot hole. Multiple reams will be carried out until
the diameter is large enough to install the 800mm trunk water main. Stage two
is expected to take about five to six weeks, weather and ground conditions
The drilled hole
will be cleaned and prepared for the pipeline installation. The high density
polyethylene (HDPE) pipe will be laid out in a single ‘string’ along the rail
siding at Murarrie and placed on rollers. The pipe is then pulled back towards
the entry point in Pinkenba until the pipeline is installed.
The above video shows the pipe pullback stage of horizontal directional drilling on one of our Scenic Rim projects. This same method will be used to pull the pipe through the tunnel under the Brisbane River.
What can you expect?
- A 250 tonne drill rig and equipment will be set up on the grassed area at the river end of Holt Street, Pinkenba.
- A 100 tonne drill rig and equipment will be set up at the existing construction site between Paringa Road and Queensport Road North, Murarrie.
- Noise from the 24/7 operation of the drill rigs.
- Removal of spoil using trucks and associated dust
will construction impacts be managed?
We will work
closely with businesses impacted by construction to address any concerns during
the project, in addition to:
- monitoring noise levels to ensure work methods are appropriate
- using approved traffic management to ensure the safety of road users and pedestrians
- dust will be managed at source using water suppression as required.
The project team is committed to minimising the construction impacts on our customers. Once construction starts, 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.
