South Sewer Main Relining

Project description

TasWater’s sewer relining program is a result of previous CCTV investigations that were undertaken to analyse sewerage “hot spots” across southern Tasmania that require relining to improve the security and performance of the sewerage pipeline system.

To reline the sewer, TasWater’s contractors will access maintenance holes to insert a liner into the sewer pipe. The pipe is then exposed to steam, through the sleeve, to cure and restore the pipe. This process clears the pipes of debris and roots.

Southern locations include:

  • Kingborough
  • City of Hobart
  • Clarence
  • Glenorchy
  • Sorell
  • Derwent Valley
  • Central Highlands

Community impact

To perform these works, we will be accessing maintenance holes to insert a new liner inside the existing sewer pipeline, then applying steam to cure the liner before restoring the pipeline for use. This is a trenchless method of sewer renewal to minimise impacts; however, residents may notice some temporary odour, construction vehicle movements and additional vehicle noise if you are in the vicinity of the works.

No interruptions to your sewage service are planned as part of these works.

Temporary traffic management directions may be placed in your area for the safety of our contractors. Please follow all signs and drive safely.

If any works may impact short term access to your property via the driveway, our contractor will discuss this with directly by door knocking when works are about to commence. All authorised personnel will carry a TasWater induction card, which you may ask to see.
