The tunnelling stage
of the Kenmore-Jindalee Cross River Pipeline project is now underway.
Tunnelling is nearing completion with break-through of the tunnel borer into the shaft at Jindalee expected early next week (w/c 7 August 2017). Approximately 530 metres of the 560 metre drive has now been completed.
Following break-through, there will be 3 days of continuous work (24hrs/day) at the worksite in Jindalee (behind the Scout Hall), to extract the tunnel borer from the shaft under hyperbaric conditions.
24 hour work hours are required to remove the tunnel borer as there is a risk of flooding the shaft during this operation and damaging the machine.
There may be noise impacts from crane movements onsite during night works.

Once tunnelling is complete, the new water and sewer pipes will be constructed above ground in Kingfisher Park, Kenmore and ‘pulled’ through the tunnel. The tunnel will then be filled with concrete grout to seal the pipes in place and the final connections to our existing networks made on each side.
Over the coming months, further connection work in Jindalee will also take place, including installing a new aerial pipe over the creek behind Kooringal Drive, which will connect the new sewer main to existing infrastructure. Further updates will be provided as work is scheduled.
- Construction noise in Kingfisher Park, including the operation of tunnelling machinery, truck movements including reversing safety beepers, and generators.
- Dust may be visible during shaft excavation and backfilling activities and will be monitored and managed at source, using water suppression, as required.
- Changed traffic conditions including reduced speeds on Gem Road and Sunset Road in Kenmore.
- Lighting in Kingfisher Park during night works.
- Increase in truck movements in Kenmore (please see truck route map below) with approximately 15 truck movements anticipated per day.
How will impacts be managed?
We will work closely with residents impacted by construction during the project, as well as:
Monitoring noise levels to ensure work methods are appropriate.
A sound wall will be constructed around the worksite to suppress noise during night works.
Truck movements will be restricted to no later than 6pm daily to minimise noise during night work.
- Directing site lighting away from residential properties.

- Full restoration of Kingfisher Park, Kenmore and the area behind the Scout Hall in Jindalee, including landscaping will be carried out on completion of the project.
