Water Main Leak Detection Across BC
Find leaks in buried water mains without excavating the entire line
About This Service
Water main leaks waste thousands of litres daily and can cause sinkholes, road failures and foundation damage if left undetected. We locate leaks in municipal-size and private water mains using acoustic correlation, ground microphones and tracer gas — marking the exact spot above the leak so excavation is a single targeted pit, not a trench across a property or road.
Signs You May Have This Leak
Detection Process
- 1
We confirm the leak with meter observation and pressure testing.
- 2
Ground microphones sweep the main's route, locating the loudest acoustic signal.
- 3
A leak-noise correlator calculates the exact position between two access points.
- 4
GPR confirms the main's route and maps any surrounding void or saturation.
- 5
We mark the surface directly above the leak and provide a depth estimate.
What You Receive
- Exact leak position marked on the surface
- Estimated depth and pipe diameter for excavation planning
- Correlation measurements and confidence assessment
- GPR scan if void or saturation mapping is needed
- Written report for property owner or municipal maintenance

Frequently asked questions
Can you find a leak on a pressurised main without shutting it down?
Yes. Acoustic methods detect the sound of escaping water from a pressurised line without interrupting flow.
What size of main can you locate leaks on?
We work on lines from residential service pipes to large-diameter distribution mains. The method scales to the main size and material.
How precise is the location?
Leak-noise correlation typically places the leak within a metre or less of the actual point, reducing excavation to a single small pit.
