South Auckland
After the aged water mains at a residential property in South Auckland had many failures, Utility Works was contracted to renew the system. The project involved services detection, concrete cutting, and hydro-vac trenching to minimise risk and damage to other services in the work zone. The new water mains were installed with a new inlet valve, toby, and relayed concrete, and the property reinstated to its original condition.

South Auckland
A large retirement village of 58 units in South Auckland had been experiencing underground water loss. Utility Works conducted system loss testing, system mapping, mark-out and CCTV/sonde pinpointing of joint and tapping band positions, isolation point installation, followed by acoustic and infrared detection works. Once leak positions were located, we implemented strategic excavation and pipe repairs, followed by ground reinstatement and site clean-up. This successful project resulted in the accurate locating and repair of five leak positions, and provided substantial water savings to the client.
