Irrigation System Leak Mapping in Chilliwack, BC
Golf courses, sports fields, parks, and agricultural operations — buried irrigation leaks, broken laterals, and chronic overwatering zones mapped across the whole property in one flight instead of weeks of walking. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Chilliwack and the Fraser Valley region — since 1999 as BC's leak detection specialists.

Flying Chilliwack: local context
Agri-industrial corridor with large low-slope roofs and military-heritage buildings.
Local property profile: Dairy and berry operations, fast-growing Sardis subdivisions, and military lands with legacy buried infrastructure.
Ground conditions: Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland.

How the Chilliwack survey runs
- 1
System review
Irrigation as-builts, zone maps, and the operator's trouble list focus the survey — which zones run long, where pressure sags, what the water bill says.
- 2
Property flight
Thermal and visual capture across the full irrigated area in the right moisture-contrast window — typically pre-dawn or evening, after a defined dry-down period.
- 3
Moisture anomaly mapping
Saturated zones that should be dry (leaks, stuck valves, broken laterals) and dry zones that should be wet (blockages, failed heads) are mapped and keyed to the zone-and-valve layout.

Operator report
A property-wide moisture map with ranked repair targets — the superintendent or parks crew fixes from a list, not from symptoms.
Chilliwack questions, answered
How does aerial imaging find buried irrigation leaks?
Two signals, flown together. Thermal shows soil moisture directly — a leaking lateral keeps its surrounding soil saturated and thermally distinct through dry-down periods. Visual imagery shows the vegetation response — the lush stripe over a leak, the stressed patch behind a blockage. Where both signals agree, confidence is high enough to dig.
How much water does a leaking irrigation system actually lose?
A single broken lateral can pass thousands of litres per irrigation cycle, invisibly, for an entire season — multiplied across a property with hundreds of zones. Under metered municipal rates and summer watering restrictions, operators consistently find the survey pays for itself in one billing cycle when it catches even one significant leak.
When is the best time to fly an irrigation survey?
During the irrigation season, after a scheduled dry-down — long enough that properly functioning zones have surface-dried while leak-fed soil stays wet. Pre-dawn flights give the cleanest thermal contrast. We coordinate the dry-down schedule with your superintendent so the survey reads true.
Can you legally fly drone leak surveys in Chilliwack?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Chilliwack flights run under whatever airspace authorizations the location requires. Agri-industrial corridor with large low-slope roofs and military-heritage buildings. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How do Chilliwack ground conditions affect what the survey reads?
Chilliwack ground is predominantly Fraser floodplain gravels and sands with mountain-fan gravels at the valley edges. Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland. 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.
What does irrigation system leak mapping cost in Chilliwack?
Province-wide pricing — no regional premium for Chilliwack. 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.
