Water Leak Detection in Dorset
Specialist leak location for commercial sites, insurers, property managers and domestic water supplies
An underground water leak can waste significant volumes of water while causing disruption, increased costs and damage to surrounding ground.
Dorset Drainage Services uses specialist equipment and experienced engineers to locate underground supply-pipe leaks before carrying out or planning repair work.

Commercial & Industrial Leak Detection
Locating an unknown leak across a large site can otherwise involve significant exploratory excavation.
Our leak-detection service can assist:
- Industrial sites
- Commercial premises
- Managed estates
- Schools
- Healthcare and public buildings
- Construction sites
- Insurers and loss adjusters
- Farms and rural properties
- Housing developments
- Domestic properties

How We Locate Underground Leaks
No single method is appropriate for every site. One technique used by Dorset Drainage Services is an electronic ground microphone, which amplifies sound generated by pressurised water escaping from buried pipework.
Depending on the situation, engineers may combine several detection technologies to narrow down the likely source.
Our leak-detection capability can include:
- Ground microphones
- Leak correlators
- Acoustic data loggers
- Cameras
- Trace equipment
- Sensing equipment
The objective is to investigate intelligently before unnecessary excavation is undertaken.
Leak Detection for Insurance Claims
Water leaks can require evidence of likely leak location, damaged pipework, required excavation, repair undertaken and reinstatement required. For insurers, loss adjusters and property owners, we can combine investigation with practical repair capability.
Request an insurance investigation
Provide the claim reference, property details and any information already supplied by the water company or another contractor.
Locate, Repair & Reinstate
Dorset Drainage Services does more than locate leaks. Where required, we can expose the defect, complete water-pipe repair and reinstate affected surfaces or hard landscaping.
Where longer pipe replacement is preferable, impact moling may also reduce the amount of open excavation required.

Signs You May Have an Underground Leak
- Unexplained water usage
- A continuously running meter
- Damp or unusually wet areas
- Reduced supply performance
- Sound of running water
- Surface movement
- Previous supply-pipe failures
- A suspected leak identified by your water provider
These symptoms do not by themselves confirm the location of a leak, which is why investigation is important before repair.
Commercial Site Investigations
On larger sites, tracing the route of a supply and narrowing down a suspected leak can reduce unnecessary disruption to operational areas. Where available, site drawings, meter data and previous repair records can all help the investigation.
Domestic Leak Detection
We also investigate leaking underground water supplies serving individual properties. Where possible, locating the problem before excavation can reduce unnecessary disturbance to gardens, drives and other finished surfaces.
