Geothermal Industries Australia (GIA) was engaged to deliver the geothermal drilling scope for a residential project in Wildes Meadow, located in New South Wales’ picturesque Southern Highlands. The project required drilling seven geothermal probes to a depth of 120 metres each on a site known for its challenging terrain and testing geological conditions. The Southern Highlands is characterised by elevated topography, cold winter temperatures, and complex underlying geology including shale, sandstone, and basalt intrusions. Working through variable ground conditions and the region’s notorious weather, GIA’s experienced team successfully drilled all seven boreholes to the full 120‑metre specification. Our team employed real‑time geological logging and adaptive drilling techniques to navigate the subsurface complexities, ensuring each borehole was completed with precision and without compromise to the surrounding environment.
For this installation, GIA utilised our 45DN Muovitech Turbo pipe as the geothermal probe material. The 45DN diameter was selected for its excellent thermal transfer characteristics and hydraulic efficiency over the 120‑metre depth, critical for a Southern Highlands property where heating demand dominates for much of the year. Muovitech Turbo pipe’s robust construction and high burst pressure ratings proved invaluable given the hard rock and variable ground conditions encountered at Wildes Meadow. Each of the seven probes was carefully installed, thermally grouted to maximise ground contact, and pressure‑tested to verify system integrity. The combination of GIA’s drilling expertise and the high‑performance Muovitech Turbo pipe delivered a reliable, energy‑efficient geothermal loop field that will provide consistent, silent heating and cooling for the residence through the Southern Highlands’ cold winters and mild summers.
Finally, GIA extends its sincere thanks to the residential plumbing contractor and homeowner for engaging us on this Wildes Meadow project. Their trust in GIA’s ability to deliver on a challenging Southern Highlands site was greatly appreciated. We look forward to future opportunities to bring our geothermal drilling expertise to more projects across the Southern Highlands and surrounding regions.
