Unitywater set to release significant drilling tender

The Queensland utility is planning to release a tender for two large pipeline projects on the Sunshine Coast, both of which will include significant lengths of trenchless construction.

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.

Engineers from Unitywater have already identified large sections of these project were Trenchless Technology will be the best construction method.

Overview of proposed projects

Nicklin Way, Caloundra Project

The project will include the construction of approximately 2470 m of OD900 mm PE100 sewer rising main on Nicklin Way.

Approximately 1520 m will be installed using horizontal directional drilling (HDD) over two sections along the Nicklin Way, located at Sugarbag Road (990 m) and Seagull Avenue (530 m).

In addition to this, two 60 m section will be constructed under Caloundra Road using microtunnelling.

Mountain Creek Project

The Mountain Creek project will see the construction of approximately 3260 m of OD900 mm PE100 rising main from north of the Mooloolah River through to the Kawana Sewage Treatment Plant.

Work will include the HDD installation of four sections of pipeline totaling approximately 1690 m.

The alignment includes an 890 m and a 350 m drill under the separate sections of Mooloolah River, and a 75 m section under Kawana Way that will be installed using microtunnelling.
