Your network is telling you where it leaks. We listen for a living.

The systematic location of leakage on public distribution and transmission systems — mains, services, hydrants, and valves — using acoustic correlation, noise loggers, zone flow analysis, step testing, and aerial thermal screening. The goal is a ranked, pinpointed repair pipeline rather than reactive break-chasing: utilities commonly lose 10–30% of treated water to leakage, and nearly all of it is findable.

Scale, method mix, and accountability. A house leak is one search; a municipal program is hundreds of kilometres of pipe, mixed materials, sparse access, and numbers that must survive council scrutiny. Network work runs on survey routes, night windows, zone meters, and statistical listening — then ends exactly like every Leak.ca job since 1999: a paint mark accurate enough to dig once.

Sequenced for payback: appurtenance cleanup first (cheap wins, false signals removed), noise loggers and aerial thermal screening to rank the network, acoustic correlation surveys to pinpoint, DMA night-flow analysis and step testing where acoustics struggle, specialist low-frequency work on trunk mains, and the water-balance accounting that wraps it into an NRW program. No single method wins alone; the sequence does.

Yes — that is the structural advantage. Our drone thermal surveys screen kilometres of corridor into ranked suspect zones; our ground crews correlate and pinpoint them to dig accuracy. One vendor, one evidence chain, no gap between a 'finding' and a repairable location. Drone-only operators can't confirm; survey-only crews can't screen at network scale. We do both.

Quoted by network size and scope, province-wide pricing with no regional premium — single investigations start in the high hundreds, systematic surveys are priced per kilometre or per zone, and programs are structured so located-leak recovery outruns program cost. The free phone consult (604-239-9934) with your system length and material mix produces a firm number quickly.

They're often where the math works best — small systems have proportionally high losses, thin staffing, and no in-house detection capability, so a focused survey week delivers years of catch-up. We scope to delegated purchasing limits, and several services (appurtenance surveys, logger campaigns) are deliberately structured as small, provable first engagements.

Active breaks get scheduling priority — typically same or next day across our BC coverage depending on crew position, fastest in the Lower Mainland. The deliverable is precision: the break correlated and marked so your excavator digs once, in the right place, and the road reopens on the short schedule. Mon–Sat, 8am–6pm PT.

All 47 cities in our coverage and the regions between them — Metro Vancouver, Fraser Valley, Vancouver Island, Okanagan, Sea-to-Sky, Sunshine Coast, Kootenays, Cariboo, Thompson-Nicola, Shuswap, Columbia, and the North. Every city carries dedicated service pages; every region has its own program page with local system context.
