Municipal Water Mains · Active breaks
Water Main Break Location for BC utilities.
Water is up through the pavement on 4th Avenue — but the break is rarely under the puddle. Precise location of active main breaks before the excavator arrives: one hole, the right hole, with the road closed for hours instead of days.

Why utilities choose it
- Stops the second and third exploratory holes
- Confirms which pipe is actually broken before digging
- Cuts road-closure and restoration hours directly
- Same crews, calm method, under pressure

How it runs
- 1
Rapid triage
Pressure data, surfacing pattern, and system maps frame the suspect span. Active breaks get scheduling priority — when a municipality is losing supply and a road, we move.
- 2
Correlate the span
Sensors bracket the suspect length and correlate the break noise — loud and broadband on a true break, which is the one mercy of the situation. Surfacing location is treated as a clue, never the answer.
- 3
Confirm at the mark
Ground microphone over the correlated position verifies maximum intensity at the mark, not at the puddle. Where utility congestion warrants, our locating and GPR capability confirms what else lies in the dig box.
- 4
Hand off to the excavator
Paint, coordinates, depth context, and the evidence trail — handed to your crew or contractor. One excavation, the right excavation; the road reopens on the short schedule.
Ground crews + aerial screening, one company
Leak.ca has pinpointed BC water leaks on the ground since 1999 — and now screens whole corridors from the air first when the network scale justifies it. Our drone thermal water main survey ranks kilometres into suspect zones; the crews on this page turn those zones into paint marks. One accountable program from flight to dig sheet — see the full municipal water main hub.
Utilities ask
Why is the break never under where the water surfaces?
Because pressurised water escaping a main takes the path of least resistance through the trench — and pipe bedding gravel is a superb conduit. Water travels along the bedding, sometimes tens of metres, until it finds a weak spot in the surface: a utility cut, a trench edge, a low joint. Digging at the puddle finds wet gravel and an intact pipe. Correlating the noise finds the break. Every veteran works crew has a story about the second and third hole; the correlator is how those stories end.
How fast can you attend an active break?
Active municipal breaks get priority in our scheduling — typically same or next day across our BC coverage, subject to crew position and travel; Lower Mainland response is fastest. Honest note: we are the location specialists, not the repair contractor — the win is that when your excavator arrives, it digs once, in the right place. Mon–Sat, 8am–6pm PT: 604-239-9934.
Can you find a break that hasn't surfaced at all?
Yes — those are routine: pressure drops or meter spikes say a main let go, but the water is disappearing into a storm drain, a gravel seam, or soft ground. The acoustic approach is identical (a break that size is loud); without surface clues the correlation simply does all the work. These hidden breaks are also the expensive ones if left — finding them within days instead of weeks is real money.
Do you check what else is in the ground before our crew digs?
On request, yes — and on congested corridors we recommend it. The same visit can include electromagnetic locating and GPR over the dig box, so the excavation that fixes the water main doesn't find the gas service the hard way. One mobilisation: break position plus a cleared dig window. See our utility locating services for the full discipline.

Acoustic Water Main Leak Survey
Systematic acoustic survey of municipal distribution networks — correlators, ground microphones, and listening points worked block by block until every leak on the route list has a paint mark and a record. The backbone method of every serious water loss program since long before anything flew.
View serviceTrunk & Transmission Main Leak Detection
The big pipes play by different rules: low-frequency leak noise, long runs between contact points, and failure consequences nobody wants to meet. Specialist acoustic methods for transmission and trunk mains — found early, while the fix is still a scheduled repair instead of a crater.
View serviceHydrant & Valve Leak Survey
The fittings leak too — and they lie. Passing gate valves mimic main leaks, hydrant drain weeps run for years uncounted, and chamber floods get blamed on groundwater. A systematic appurtenance survey cleans up both the losses and the false signals confusing every other method.
View serviceStep Testing & Zone Isolation
Close valves in a planned sequence, watch the zone meter, and the leak tells you which segment it lives in. Step testing is the old, unglamorous, devastatingly effective way to shrink a leaky zone to a few hundred metres of main — before acoustic crews finish the job.
