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 investing around $350,000 into replacing the sewer maintenance holes and relining the existing sewer system at Somerset Dam.

What is happening?

From week commencing 29 May 2017, for approximately three weeks, our contractor, Interflow, will begin replacing the existing sewer maintenance holes at Somerset Dam as they are nearing the end of their operational life. This work will be completed Monday to Saturday between 6am and 6pm. Work will occur in Main, King and Gully Streets.
Following the construction of the new sewer maintenance holes, Interflow will reline the sewer by using an innovative trenchless technology called spiral-winding that eliminates the need to dig up damaged pipes. Sewer relining will commence in late-June/early-July 2017. Residents will receive further information about the relining work, including the construction start date, relining impacts and work hours closer to the time.

What can I expect during the sewer maintenance hole replacement work?

Noise and dust

This work involves noise and dust generating activities including:

  • excavating, potholing and drilling
  • heavy construction vehicle movements
  • engine and vacuum noise.


The work may cause some odour when lids on maintenance holes are removed to allow access, and when pipes are ventilated to ensure the safety of workers in confined spaces.

Traffic management

There may be changed traffic conditions while work is underway. Residents are asked to travel through the area with care and observe all signposting, speed limits and any directions given by traffic controllers.

How will maintenance hole construction impacts be managed?

The project team will manage the construction impacts by:
  • monitoring noise levels to ensure work methods are appropriate
  • managing dust at source, using water suppression, as required
  • using approved traffic management to ensure the safety of road users and pedestrians
  • odour will be monitored and mitigated, to the extent possible, without compromising safety.
  • temporarily restoring disturbed roads, driveways and footpaths to allow for continued use while work is in progress
  • fully restoring all work areas, including driveways and footpaths, as close to original condition as possible, once the work is completed.
