Trenchless delivers critical pipeline in Tasmania

TasWater HDD, trenchless technology

Trenchless technology played a critical role in delivering an important water pipeline in Launceston, Tasmania.

The 3km pipeline was installed 40m underneath the Tamar Estuary River (also known as Kanamaluka) in Launceston, redirecting sewerage and stormwater flows to the Ti Tree Bend sewerage treatment plant. This is expected to help preserve the river for years to come by preventing overflow events.

Delivered as part of the $140.7 million Tamar Estuary River health action plan (TERHAP), the pipeline will increase TasWater’s ability to manage Launceston’s combined sewage and stormwater system.

TERHAP is a key initiative of the collaborative $603 million Launceston city deal, which saw funding to the tune of $49 million from the Australian Government, $42.5 million from the Tasmanian Government, $33.2 million from TasWater, and $11 million from the City of Launceston.

Delivery of the project was made possible by TasWater, as well as a range of government bodies and suppliers, including principal contractor Pipeline Drillers Group, an expert in trenchless technology. It is understood that horizontal directional drilling was used to construct the pipeline.

“The estuary is incredibly important to our community, and the City of Launceston is proud to support TERHAP with a funding commitment of $11 million,” City of Launceston Deputy Mayor Hugh McKenzie said.

“This is one of the largest infrastructure projects of its type in the southern hemisphere, and once completed the pipeline will significantly improve the overall health of the waterway by reducing the frequency and volume of overflow events.

“We congratulate TasWater for the extensive work that’s been done to reach this important milestone, in what will prove to be a transformative project for our city’s combined sewer and stormwater network.”
