Underground Water Main Leak Survey in Nanaimo, BC

Not the pipe itself — the surface expression of the leak. Water escaping a pressurised main saturates the surrounding soil, and saturated soil heats and cools differently than the dry ground beside it. A radiometric sensor with ≤50 mK sensitivity measures that differential along the corridor. It is a screening method: it tells ground crews where to listen, which is exactly what makes network-scale surveys affordable.

Utilities commonly lose a meaningful share of treated water to distribution leakage — industry reporting puts typical systems anywhere from 10 to 30 percent. The expensive part of recovering it is finding the leaks. Aerial screening compresses kilometres of network into a ranked shortlist of suspect zones, so acoustic crews spend their hours confirming leaks instead of hunting for them.

Ground-based acoustic correlation — the same Leak.ca crews who have pinpointed BC water leaks since 1999. We deliberately keep both halves in-house: the aerial survey ranks the corridor, the correlator puts a paint mark on the road. You get one accountable report, not two vendors pointing at each other.

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Nanaimo flights run under whatever airspace authorizations the location requires. Harbour city with hospital-area densification; YCD-adjacent operations under authorization. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

Nanaimo ground is predominantly till and sandstone benches — with documented historic coal workings beneath parts of the city. Standard till performance at surface, but Nanaimo's defining subsurface feature is its coal-mine legacy: old workings and shafts underlie several neighbourhoods, making void detection a local specialty. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.

Province-wide pricing — no regional premium for Nanaimo. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
