Mains water leaks
Acoustic detection can help narrow leak locations on pressurised mains water supplies.
Technology
Acoustic Leak Detection
Acoustic leak detection uses specialist listening equipment to identify sound patterns created by escaping water from pressurised pipework, underground services and concealed water systems.
It is especially useful for mains water leaks, underground pipework, external supply pipes and hidden leaks where visual evidence is limited.

Investigation method
What Is Acoustic Leak Detection?
Acoustic leak detection uses specialist listening equipment to identify sound created by escaping water from pressurised pipework. The equipment helps engineers listen for leak noise through floors, pipe routes, fittings and external ground surfaces.
Ground microphones or acoustic sensors can be used to narrow the likely location of hidden leaks, especially where pipework is concealed and visible evidence is limited.
Investigation principle
Listen For Leak Noise
Escaping water can create sound in pressurised pipework. Acoustic equipment helps identify where that sound is strongest so access or repair work can be better targeted.
Use cases
When Is Acoustic Detection Used?
Underground pipework
Listening equipment can identify leak noise from concealed pipework below external surfaces.
External supply pipes
Supply pipe routes can be investigated before excavation is planned.
Commercial water systems
Pressurised pipework in commercial properties can be assessed with minimal disruption.
Leaks under concrete
Acoustic testing can support investigation where pipework is hidden below solid floors.
Trace and access investigations
Acoustic evidence can help inform access recommendations for concealed leaks.
Advantages
Advantages Of Acoustic Detection
Non-destructive
Acoustic detection helps assess leak locations before opening up or excavation.
Useful externally
The method is well suited to external supply pipes, hardstanding and underground services.
Supports underground leak location
Leak noise can help narrow the likely position of hidden underground water leaks.
Helps reduce excavation
Targeted findings can help avoid unnecessary digging across large areas.
Works with pressurised systems
Acoustic investigation is most useful where escaping water creates detectable sound.
Can support insurance investigations
Results may contribute to written findings, photographs and trace and access evidence.
Method limits
Limitations Of Acoustic Detection
Acoustic detection is effective on many pressurised leaks, but results can be affected by pipe material, depth, water pressure, background noise and surface conditions.
Ground conditions, pipe routes and surrounding building noise can all influence readings. For that reason, acoustic detection may be combined with tracer gas, thermal imaging or moisture mapping.

FAQs
Acoustic Leak Detection FAQs
What is acoustic leak detection?
Acoustic leak detection uses specialist listening equipment to identify sound created by escaping water from pressurised pipework.
Can acoustic detection find underground leaks?
Yes. Acoustic detection can help locate underground leaks where water escaping from pressurised pipework creates detectable noise.
Does acoustic leak detection damage property?
No. Acoustic testing is non-destructive and is used to narrow likely leak locations before excavation or access work.
Does acoustic detection work on all pipework?
No. Results depend on pipe material, pipe depth, pressure, background noise and surface conditions. Other methods may also be required.
Is acoustic detection used with tracer gas?
Yes. Acoustic detection is often used alongside tracer gas, thermal imaging or moisture mapping to build a clearer investigation picture.
