Municipal Water Main Leak Detection in BC
Every litre of treated water lost to a hidden main leak is water a community paid to source, treat and pump for nothing. This is British Columbia's educational hub for finding and reducing those losses across the distribution network.
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.
Recover non-revenue water
Locate the background leakage that quietly drains treated supply before it's billed.
Reduce main breaks
Find weakening pipe and manage pressure to slow the rate of new failures.
Target capital
Survey before renewal so investment goes to the pipe that's actually failing.
Municipal Leak Detection Services
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.
Large-diameter supply mains carry huge volumes — a single leak is a major, hard-to-hear loss.
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.

Municipal Leak Detection FAQ
It is the systematic location of leaks on a municipality's buried water network — distribution mains, service connections and transmission lines — using acoustic listening and leak-noise correlation. It lets a utility pinpoint and repair leaks before excavating, recovering treated water lost to background leakage and reducing main breaks.
A large share of treated water is lost before it reaches customers — non-revenue water — much of it through hidden leaks on aging mains. Across British Columbia, freeze-thaw in the Interior and North, soft delta soils in the Lower Mainland and aging cast-iron and asbestos-cement pipe all drive leakage. Detection recovers that water and the energy used to treat and pump it.
Acoustic surveys (listening at valves and hydrants), leak-noise correlation (pinpointing to within inches), acoustic noise loggers (continuous monitoring), district metered areas (zone-level leakage trends) and utility locating (mapping the buried network) are combined based on pipe material, diameter and depth.
Leaks.ca is the educational hub. Professional, on-site municipal leak detection and water-loss surveys across British Columbia are provided by our service partner Leak.ca.
