Unitywater has announced a tendering opportunity for two major trenchless pipeline projects in Queensland.
The two projects include the construction of sewer rising mains totalling 5,730 metres, as well as three significant pump station upgrades at two sites.
Approximately 60 per cent of the sewer rising mains will be constructed using trenchless methods.
The Nicklin Way, Caloundra Project consists of constructing approximately 2470 metres of OD900mm PE100 sewer rising main on Nicklin Way.
Engineers from Unitywater have identified approximately 1520 metres of the rising main and two 60 metre micro-tunnels that require trenchless construction.
Unitywater said these projects provide an exciting opportunity for experienced drilling companies to work with Unitywater in the delivery of critical network infrastructure for the growing community.
The second project, Mountain Creek, will see the construction of approximately 3260 metres of OD900mm PE100 rising main from north of the Mooloolah River through to the Kawana Sewage Treatment Plant.
Four sections of the Mountain Creek rising main, totalling 1690 metres, will use horizontal directional drilling (HDD).
The alignment includes an 890 metre and a 350 metre drill under the separate sections of Mooloolah River and a 75 metre micro-tunnel under Kawana Way.
The two tenders equal approximately $30million in value.
The design and construct tender packages are scheduled for release on the QTenders website in late March 2016.
