The cousins Kane and Nathan O’Meley, aged 19, work for Arogen who was contracted for Country Energy’s project to connect Three Chain Road to Country Energy’s South Lismore zone substation, with high-voltage underground cables.
Directional drilling was required in two locations, in the area outside the South Lismore Sewage Treatment Plant in the western area of Tree Chain Road and underneath the Bruxner Highway.
The site of the possible world record, South Lismore Sewage Treatment Plant, used 2 bores in basalt 1.5 m separation with a minimum casing size of 600 mm internal and a bore length of approximately 220 m. The bore is to contain 7 x 180 mm plus 2 x 110 mm orange conduits and 2 x 100 mm white conduits.
The work was completed with a D100X120 Series II Vermeer Drill.
Two more bores were used for under the Bruxner Highway with 1.5 m separation, a minimum casing size of 600 mm internal steel casing and a bore length of approximately 100 m. The bore is to contain the same as above.
Country Energy is planning a seven year, $A70 million upgrade of its electricity network in Ballina Shire, Byron Shire and Lismore City local government areas to secure power supply for the future.
The Lismore to Mullumbimby upgrade is part of Country Energy’s almost $A4 billion network investment program over the next five years.
