Transmission & Trunk Main Leak Detection in British Columbia
Transmission and trunk mains are the large-diameter pipes that move bulk water between sources, reservoirs and districts. Their size and depth make leaks quieter and harder to localize, while the volumes they carry make any leak a significant loss. Specialized correlation, in-line acoustic methods and careful sensor placement are used to locate them.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
- Correlation tuned for large-diameter, low-frequency leak signals
- Extended sensor spacing using valves and chambers as access
- In-line and tethered acoustic methods for the longest runs
- Coordination with operations to survey under controlled conditions
- Major bulk-supply losses located before they become failures
- Critical infrastructure protected with minimal disruption
- Targeted intervention on high-consequence assets
Transmission & Trunk Main Leak Detection — FAQ
Large-diameter mains carry leak sound at lower frequencies that attenuate quickly, and access points are far apart, so a leak can be quiet at the surface despite losing large volumes. Correlation tuned for large pipe, wider sensor spacing and in-line acoustic methods address this.

Pinpoint leaks on buried distribution and transmission mains without excavating the whole street.
Recover treated water lost to leaks before it reaches customers — and target the worst losses first.
Walk the network listening at every valve and hydrant to surface hidden background leakage.
Two sensors on the main, one mathematical fix — leak position to within inches on long runs.
Divide the network into measured zones so rising night flow flags leakage early.
Right-sizing pressure cuts both leakage volume and the rate of new breaks.
Hydrants and valves are the network's listening posts — and assets worth checking themselves.
Deploy loggers across a zone to listen overnight and report where new leakage appears.
Before a main renewal program, know which segments are actually leaking and failing.
Locate the break, find any related leakage, and document the failure for the record.
Know exactly where the buried main, valves and connections run before any work.
