What it is
Once a leak has been located, we open the ground at that one spot, cut out the damaged section of pipe, fit a permanent repair and put the surface back the way it was — concrete, asphalt, grass or paving.
When you need it
- A leak has been pinpointed under a driveway, path or lawn.
- A burst pipe is losing water and needs a permanent fix, not a clamp.
- Your plumber has located the loss but does not do excavation.
What you get
- The damaged pipe section replaced with a watertight, permanent repair.
- The hole backfilled, compacted and the surface reinstated to match.
- Photos of the exposed pipe, the fault and the finished repair.

South Auckland
Retirement Village Water Leak Detection & Repair
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.

West Auckland
Campus Leak Detection & Repair
After suffering long-term issues with water loss, system configuration and location, Utility Works was engaged to find and repair the leaks at a West Auckland campus. The site spanned over 150 acres with extensive buildings and intertwining historic and modern piping networks. The project involved extensive system isolation and configuration testing, GPR and pipe tracing, re-mapping and full leak detection surveying. Once the losses were located, over 14 underground leaks were excavated and repaired. From initial engagement to completion of the first stage of repairs, the campus saw an 83% reduction in minimum night-flow loss.

Who Owns the Pipe From the Street to Your House? Point of Supply, Responsibility and Leak Remissions in NZ
When water starts pooling in the berm or the bill doubles, the first question is who has to fix it. The answer depends on which side of the point of supply the problem sits, and that line is drawn in a slightly different place on urban, rural, cross-lease and unit-title properties. This guide explains where it is, what the water supplier will and will not do, how shared pipes and tenancies work, and how to claim back some of the water a leak cost you.
