Municipal Water Mains · BC Region
Water main leak detection across the Fraser Valley.
Valley municipalities largely own their sources and balance urban cores against working agricultural land — long rural mains, floodplain soils that hide surface expression, and systems that grew outward fast through the postwar AC-pipe era. Leak.ca crews have worked BC water systems since 1999 — acoustic surveys, logger programs, zone analysis, break location, and full NRW campaigns, with aerial thermal screening when network scale calls for it.
Long runs with sparse connections suit logger campaigns and aerial corridor screening; floodplain ground means leaks can run a long time before anyone sees water.

Fraser Valley communities we serve
Every community carries dedicated service pages with local ground-condition context:
Langley
Till and gravel scan 2–3 m cleanly across most of the township; lowland silt pockets shorten range locally.
Acoustic survey·Break location·NRW program·All Langley services
Maple Ridge
Bench neighbourhoods scan conventionally; floodplain and river-corridor properties run wet with reduced depth.
Acoustic survey·Break location·NRW program·All Maple Ridge services
Pitt Meadows
Among BC's wettest GPR ground; shallow imaging works, deep targets need EM and acoustic support. Drainage infrastructure density is the defining local feature.
Acoustic survey·Break location·NRW program·All Pitt Meadows services
Mission
Hillside till scans well between rock outcrops; the floodplain industrial flats are wetter. Slope properties put services shallow and traceable.
Acoustic survey·Break location·NRW program·All Mission services
Abbotsford
Upland till and gravels scan deep and clean; Sumas Prairie's silts (former lake bed) restrict depth and stay seasonally saturated — flood-recovery work taught us every corner of it.

Chilliwack
Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland.

Hope
Coarse gravels scan deep but cobble scatter adds clutter — interpretation experience matters more here than equipment.

The municipal service set
Network surveys
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 serviceContinuous listening
Leak Noise Logger Programs
Noise loggers deployed across the network — magnetically mounted in valve chambers and on hydrants, listening through the quiet hours night after night. Lift-and-shift campaigns or permanent coverage, with every point of interest ranked before a crew ever mobilises to correlate.
View serviceZone metering
District Metered Area (DMA) Leak Detection
Carve the network into measurable zones and the leaks have nowhere to hide. DMA support from boundary design and minimum night flow analysis through to the acoustic work that converts a high-MNF zone into pinpointed repairs.
View serviceNarrowing the search
Step 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.
View serviceLarge diameter
Trunk & 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 serviceAppurtenances
Hydrant & 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 serviceActive breaks
Water Main Break Location
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.
View serviceThe full campaign
Non-Revenue Water (NRW) Program
Treated water that earns nothing — leaked, unmeasured, or unbilled — commonly runs 10–30% of production. The NRW program is the umbrella: water balance to size the problem, zone data to rank it, every detection method in this hub to locate it, and re-measurement to prove what came back.

What makes Fraser Valley water systems distinctive for leak detection?
Valley municipalities largely own their sources and balance urban cores against working agricultural land — long rural mains, floodplain soils that hide surface expression, and systems that grew outward fast through the postwar AC-pipe era. Survey design here starts from those realities — methods, sensor spacing, and timing matched to the region rather than copied from somewhere flatter.
Which Fraser Valley communities do you serve?
Dedicated local coverage for Langley, Maple Ridge, Pitt Meadows, Mission, Abbotsford, Chilliwack, Hope — and the surrounding systems between them. Every community page carries its own ground-condition and water-system context; province-wide pricing applies with no regional premium.
Why run a leak program in Fraser Valley now?
Long runs with sparse connections suit logger campaigns and aerial corridor screening; floodplain ground means leaks can run a long time before anyone sees water. Distribution systems commonly lose 10–30% of treated water to leakage — the free phone consult (604-239-9934) scopes what a ranked program would look like for your network in one conversation.
