Pipeline Drillers has accomplished the highly anticipated 1.6 kilometre Nicklin Way section of the new Caloundra Sewerage Pipeline, said to be the largest and longest horizontal directional drilling installation in Australia. The HK HDD250t drill rig endured extremely hard rock to enlarge the borehole to a final diameter of 1200 mm, before the American Augers DD1100 pulled through the DN 900 mm HDPE within 72 hours.
