If you suspect an underground water leak, don’t panic– our expert team at ACS Drainage Services is here to help. 


We specialise in locating and repairing leaks on external water mains with speed, accuracy and minimal disruption to your garden. Using cutting-edge ground microphones, our trained technicians pinpoint the source of leaks: no guesswork, no unnecessary excavation.

Whether you’ve noticed a sudden drop in water pressure, a notably high bill, or water pooling in your garden, don’t ignore the signs. Leaks can waste thousands of litres of water a day and cause significant damage over time. 


Our leak detection service gets to the root of the problem fast, so you can act before the damage spreads.


What We Do


Leak Detections for External Water Mains


Our services include finding leaks on water mains that run from the external meter up to your property. This stretch of pipework is often you, homeowner’s, responsibility. Unfortunately, it can be one of the most vulnerable to leaks due to age, ground movement, or wear and tear.


We use highly sensitive ground microphones to listen for the acoustic signature of escaping water. These specialist tools allow us to ‘hear’ the leak beneath soil, concrete, tarmac or paving. That’s true even if the leak is hidden a metre underground. 


By narrowing down the source to within inches, we avoid unnecessary digging and reduce disruption to your home or business.

The Initial Consultation


We’ll discuss the symptoms you've noticed, whether it’s unusual damp patches, low water pressure or high bills. Our experts then assess whether an external leak is the likely culprit.


Professional Site Visit & Survey


One of our skilled engineers will carry out a survey using sensitive ground microphones. If needed, we may also use pressure testing or tracer gas methods to confirm the location.


Pinpointing the Leak


Once we’ve narrowed down the location of the leak, we mark it on-site and advise on the next steps for repair.
