Golf Course Pond Leak Detection in Auckland
Lined ponds pose many challenges once underground loss occurs. Utility Works was contracted to assist with the locating of pond leaks at a large Auckland golf course ahead of the dry summer months, when the irrigation system relied on the water supply. The process involved underwater diving and installation of pipe air bags to block the balance pipe and separate the two ponds, enabling accurate loss calculation, followed by GPR and IR works to determine likely areas of loss. The ponds were pumped out to enable locating of the defects for repair. We also assisted with the irrigation flow and isolation testing during the process.
