Pipeline Drillers have delivered the final horizontal directional drill (HDD) of the 3.2 kilometre Mountain Creek to Kawana Sewerage Pipeline, pulling through the new 900 millimetre high-density polyethylene pipe adjacent to one of the Sunshine Coast’s most utilised roadways, Kawana Way, in under 15 hours.

 

At 1,200 metres, this is the longest HDD, representing 37.5 per cent of the upgraded Kawana main which will improve flows to the growing areas of Sippy Downs, Mountain Creek and South Buderim.  
 

Pipeline Drillers Director John Whitbread said the location and ground conditions of this Kawana Way section presented significant challenges.
 

“Significant planning by the project team was required to overcome constraints of positioning the rig within an area less than 500 square metres, the bend in the alignment, in addition to ground conditions of sands and clays,” said Mr Whitbread.
 

“Innovative HDD design, working together with government stakeholders, and community engagement throughout the delivery phase of this project to keep close to 500 residents, three over 50’s lifestyle resorts and two schools informed were all critical elements to ensure a safe and efficient installation.”
 

Pipeline Drillers deployed a trenchless technology fleet comprised of the Gallagher HDD660, Herrenknecht 250t and CMS180 drill rigs, various combination tooling, and fibre optic gyro for accurate tracking. This ensured disturbance to the above ground environment was minimised while completing the pilot and drilling of the hole to enlarge it to its final diameter of 1200 millimetres in under 12 weeks.
 

Tie-in works will conclude this week and see equipment demobilise, with final restoration of the transport corridor, and sites between the Parrearra Channel bridge and Kawana Island Boulevard commence.
