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 built a cross-river water pipeline from Murarrie to Pinkenba, connecting two water supply zones - the Bartleys Hill reservoir in Ascot and the Wellers Hill reservoir in Murarrie.

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.

How was the pipe installed beneath the Brisbane River?

The 1.1km of water pipeline was completed using horizontal directional drilling (HDD).

  

The above video shows the pipe pullback stage of horizontal directional drilling on this project.

  • The additional infrastructure will allow us to move water between two supply zones and ensure reliable and sustainable delivery of water services for Eagle Farm, Pinkenba and Murarrie, making supply more flexible and efficient.
  • It will support demand from a growing population in the North Shore Hamilton Urban Development Area.
  • It will also provide contingency water supply in the event of an unplanned disruption or planned maintenance in one of the water supply zones.

Using horizontal directional drilling, the new pipe was fed more than 20m underground, beneath the river from Murarrie to Pinkenba.
