Leak Detection
Specialist leak detection services for water pipelines across the UK.
Leak detection testing is essential for locating leaks that may not be immediately visible during standard pressure testing. By pinpointing faults accurately, we help reduce unnecessary excavation, minimise water loss, and keep repair work focused and efficient.
What Is Leak Detection?
Leak detection uses specialised equipment and techniques to identify leaks, weak joints, or hidden failures within water pipelines. While hydrostatic testing can show that water is being lost, leak detection finds where it is being lost, allowing targeted repair and minimal disruption to the network.
Key Benefits
Confirms Hidden Leaks
Identifies small or hard-to-find leaks that may not be obvious during initial pressure testing.
Reduces Excavation & Costs
Accurate location of leaks means less digging, shorter repair times, and lower overall costs.
Minimises Disruption
Targeted repairs help maintain supply, reduce interruption, and keep projects on programme.
Our Leak Detection Methods
We select the most suitable leak detection method based on the pipe material, diameter, and site conditions. Techniques include acoustic leak detection, which listens for the sound signature of escaping water, pushrod camera systems for close-range visual inspection, pulley-driven systems for longer pipe runs, and floating camera units designed for large trunk mains. Using these approaches, we can locate leaks with high accuracy while keeping disruption to a minimum.
Compliance & Reporting
All leak detection work is carried out in line with UK water industry expectations for potable water safety, pressure testing, and infrastructure integrity. Each investigation is supported by a clear report detailing the methods used, leak locations, and recommended next steps, providing a solid basis for repair, further testing, or handover.
When Is Leak Detection Required?
Leak detection is needed when pressure tests indicate water loss, when there are unexplained drops in pressure or flow, or when there are signs of possible pipeline deterioration. It is also valuable before major repairs or refurbishment work, and when investigating persistent wet areas, ground movement, or unexplained increases in consumption. Early, accurate leak detection helps protect assets, control costs, and maintain reliable supply.
