Underground Water Main Leak Survey in Prince George, 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 Prince George flights run under whatever airspace authorizations the location requires. Northern capital with pulp, energy, and institutional campuses — industrial thermal work anchors the book; YXS airspace per authorization. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

Prince George ground is predominantly glaciolacustrine clays and silts of the Nechako plateau. Northern clays are depth-limiting when wet and frost-bound in winter — survey windows and antenna choice matter. Shallow services still image reliably year-round. 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 Prince George. 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.
