Municipal Water Mains · BC Region
Water main leak detection across the Metro Vancouver.
Member municipalities receive treated water from the regional Capilano, Seymour, and Coquitlam sources and run their own distribution systems — which range from century-old cast iron under the region's first streetcar suburbs to brand-new PVC in growth corridors. North Shore and hillside systems add aggressive pressure zones that work mains hard. 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.
Dense hydrant and valve spacing makes Metro systems ideal acoustic territory, and every recovered cubic metre is water the region didn't have to treat and pump over the mountains.

Metro Vancouver communities we serve
Every community carries dedicated service pages with local ground-condition context:
Vancouver
Till and sand image well — 400 MHz reaches 2–3 m across most of the city; signal shortens in fill zones around False Creek and the port lands.
Acoustic survey·Break location·NRW program·All Vancouver services
Burnaby
Till slopes give clean 2–3 m penetration; peat and high water table near Burnaby Lake and Big Bend cut effective depth — survey design accounts for it.
Acoustic survey·Break location·NRW program·All Burnaby services
Surrey
Upland till scans 2–3 m reliably; the Serpentine and Nicomekl floodplains run wet and silty, so deep targets there lean on EM pairing and tighter grids.
Acoustic survey·Break location·NRW program·All Surrey services
Richmond
Richmond is BC's most depth-limited GPR environment — saturated silts attenuate signal fast. Shallow targets still image well, and we compensate with EM, acoustic, and tracer methods for deeper work.
Acoustic survey·Break location·NRW program·All Richmond services
North Vancouver
Coarse till scans cleanly until bedrock ends penetration — often within 1–2 m on upper slopes. Services squeezed into that shallow band image sharply.
Acoustic survey·Break location·NRW program·All North Vancouver services
West Vancouver
Thin rocky soils put most utilities shallow and image crisply; granite below returns nothing, which itself maps where rock starts — useful for excavation planning.
Acoustic survey·Break location·NRW program·All West Vancouver services
Coquitlam
Bench till gives standard 2–3 m performance; river-adjacent alluvium runs wetter with moderate depth loss.
Acoustic survey·Break location·NRW program·All Coquitlam services
Port Coquitlam
Floodplain silts limit deep imaging south of the rail corridor; northern till scans conventionally. Shallow residential services image well throughout.
Acoustic survey·Break location·NRW program·All Port Coquitlam services
Port Moody
Inlet-edge fill is variable and can hide debris layers; the till slopes above scan cleanly. We grid fill zones tighter to separate utilities from rubble.
Acoustic survey·Break location·NRW program·All Port Moody services
New Westminster
Hilltop till scans well; the riverfront flats are historic fill with brick, timber, and rail-era debris that demands experienced interpretation.
Acoustic survey·Break location·NRW program·All New Westminster services
Delta
Lowland silts behave like Richmond — shallow water table, limited depth; the North Delta till ridge scans conventionally. Farm drainage networks add target density.
Acoustic survey·Break location·NRW program·All Delta services
White Rock
Dry marine sands are excellent GPR country — 3 m+ penetration on the upper benches; bluff-face properties need slope-aware survey planning.
Acoustic survey·Break location·NRW program·All White Rock services
Ladner
High water table keeps effective GPR depth shallow; fortunately Ladner services run shallow too. Drainage mapping relies on dense gridding plus EM.

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.
View serviceMetro Vancouver questions, answered
What makes Metro Vancouver water systems distinctive for leak detection?
Member municipalities receive treated water from the regional Capilano, Seymour, and Coquitlam sources and run their own distribution systems — which range from century-old cast iron under the region's first streetcar suburbs to brand-new PVC in growth corridors. North Shore and hillside systems add aggressive pressure zones that work mains hard. Survey design here starts from those realities — methods, sensor spacing, and timing matched to the region rather than copied from somewhere flatter.
Which Metro Vancouver communities do you serve?
Dedicated local coverage for Vancouver, Burnaby, Surrey, Richmond, North Vancouver, West Vancouver, Coquitlam, Port Coquitlam, Port Moody, New Westminster, Delta, White Rock, Ladner — 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 Metro Vancouver now?
Dense hydrant and valve spacing makes Metro systems ideal acoustic territory, and every recovered cubic metre is water the region didn't have to treat and pump over the mountains. 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.
