What's happening?

In July 2020, Urban Utilities and our delivery partner, Fulton Hogan, started construction on a new underground sewer pipeline between the Centenary Highway sewer pump station and Seventeen Mile Rocks Road, Jindalee.  

The project is expected to take up to 12 months to complete, weather and site conditions permitting.

What to expect

Temporary work sites have been established to carry out the work associated with the installation of the new underground sewer pipeline:

  • Department of Main Roads Centenary Highway road reserve: located adjacent to Centenary Highway; and Sinnamon Road, Jindalee
  • Jindalee Golf Club: Yallambee Road, Jindalee and via the existing track across the golf course, from Capitol Drive, Jindalee (opposite Pantheon Street)
  • Sinnamon Village Aged Care: site access off Oldfield Road, access track to Sinnamon Village Aged Care site compound.

Holding area for pipe used during the construction:

  • Capitol Drive Park reserve, Jindalee: located on Capitol Drive, Jindalee (next to the Jindalee Golf Club property)

Our commitment

The project team will minimise the construction impacts to the extent possible, including managing noise and dust at the source, utilising traffic control and reviewing work methods as required. 

We will keep directly impacted neighbours informed by providing regular construction updates during the project.

Work hours

The majority of the work will be carried out during the day between 7.00am and 6pm, Monday to Friday and on Saturday between 8.00am and 1pm.

Thank you for your patience and understanding while we complete this essential work.


Overview

We're installing a new under-ground sewer pipeline in Jindalee to replace the existing pipeline underneath the Centenary Highway, which will be decommissioned at project completion.

Why is the new sewer pipeline being installed at this location?

The new pipeline is being installed between the Centenary Highway sewer pump station and Seventeen Mile Rocks Road, Jindalee to allow for the new pipeline to connect to the existing sewer network.

Construction of the new pipeline

The new pipeline will be installed below ground using a combination of trenchless technology and open trench construction. Most of the construction will be completed by the trenchless technology known as horizontal directional drilling (HDD), to minimise impacts to residents and the environment.

Three temporary work sites will be established along the alignment to allow access for the HDD Rig and machinery. Most of the above-ground works will occur at these locations.

What to expect during construction?

During construction, nearby residents and businesses may experience some noise and dust from machinery increased vehicle movements and minor vibration during the drilling activities. The project team is committed to minimising the construction impacts where possible during project delivery.

 
Project delivery

The works will be delivered in partnership with Fulton Hogan.

About horizontal directional drilling

Horizontal directional drilling (HDD) allows pipes to be installed underground to minimise the need for surface disturbance through open trench activities.

Drilling activities require an entrance pit to be excavated adjacent to the drill rig, size of the pit is determined by the depth and width of the pipe.

The HDD process uses a mud material to keep the cutting drill head cool, lubricates the borehole and flushes the excavated soil back to the entrance pit. The returned mud material is sifted to remove bulk particles and reused.

To track and guide the drill head to the designated location, a transmitter or steering tool is located within the drill head which sends a signal with the exact coordinates. Once the drill is near the designated location, an exit pit is excavated and the drill comes to the surface.

Once the initial borehole is completed, drilling activities continue to increase the size of the borehole to the required diameter.Polyethylene pipe is the preferred choice for trenchless installations because of its flexibility and strength using directional drilling construction.
