021 108 6789Underground Leak Detection & Water Main Repair Auckland
Unexplained water bill or a wet patch that never dries? We locate leaks in buried water pipes, repair damaged water mains, and keep the digging to a minimum.
Find the Leak First, Then Dig Only Where It Counts
Underground water main leaks are very common in Auckland, often caused by a single failed fitting beneath a lawn, driveway or concrete slab. Because the water soaks away out of sight, the first sign is usually a shock on your water bill.
Digging a whole pipe run to find one leak is slow, messy and expensive. We use specialist equipment to pinpoint the leak from the surface, then open up only the small area needed for the repair. We cover all of Auckland, including South Auckland, and homes, rentals and commercial sites.
Signs of an Underground Water Leak
How We Find and Repair Buried Leaks
Acoustic detection
Pressurised water escaping a pipe makes a distinct sound. Acoustic ground microphones let us listen along the pipe route and narrow down the exact spot, even under concrete.
Thermal imaging
Thermal imaging shows temperature differences caused by escaping water, which helps trace leaks in slabs and walls and shows how far the water has travelled.
Lasting repair
We replace failed fittings and damaged pipe, upgrade old manifolds where needed, and reinstate the area. When a pipe is beyond repair, we can install a new water main, including by thrust boring.
We Help You Claim Back Wasted Water Charges
If a hidden leak has pushed up your bill, you may be able to get some of it back. We regularly issue a leak rebate letter for your network utility operator, Watercare or Veolia Water in Auckland. This can save customers up to around $1,000 in unnecessary water charges. On one concrete slab job, our report helped void $600 of charges for water the client never used. The operator makes the final decision on each application.

Leak under a concrete slab
Acoustic ground microphones pinpointed the leak so only a small section of concrete had to be opened. The report we supplied supported a leak rebate that voided $600 of charges for unused water.

New watermain for a Glen Innes school

Underground Leak & Water Main FAQs
How do I know if I have an underground water leak?
The simplest check is your water meter. Turn off every tap and water-using appliance, note the meter reading, and check it again after an hour or so without using any water. If it has moved, you probably have a leak. A high water bill, a permanently wet patch of ground or a sudden loss of pressure are other common signs.
Who is responsible for a leak on my water main in Auckland?
Generally, the pipe on your side of the water meter is the property owner's responsibility, and the network on the street side belongs to the water network operator. If you are not sure where the leak is, we can locate it and tell you which side of the meter it is on.
Can I get a rebate on my water bill after an underground leak?
Often, yes. We regularly supply a leak rebate letter for your network utility operator (Watercare and Veolia Water in Auckland), and this can save customers up to around $1,000 in unnecessary water charges. The operator decides each application, so it pays to keep your repair invoice and report.
Will you need to dig up my lawn or driveway?
Some digging is usually needed to reach and repair a buried pipe, but finding the exact location first keeps it to a minimum. We excavate carefully and reinstate the area afterwards. For longer pipe runs, thrust boring can install a new pipe with very little surface disruption.
How much does underground leak detection and repair cost?
It depends on the length and depth of the pipe, what it runs under and what is needed to reach it, so we confirm pricing for your property before work begins. The cost of a leak left running can be significant, so it is usually worth getting it checked quickly.
Is a broken water main an emergency?
If water is flowing freely or the property has lost supply, treat it as urgent. Turn off the main valve at your water meter if you can, then call 021 108 6789. We take emergency calls 24 hours a day, 7 days a week.
