District Energy & Buried Heat Loop Survey in Nanaimo, BC
Buried hot-water and steam distribution mapped by thermal drone — line losses, failed insulation, and active leaks on district energy systems, hospital and university campuses, found from the air in a single evening flight. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Nanaimo and the Vancouver Island region — since 1999 as BC's leak detection specialists.

Flying Nanaimo: local context
Harbour city with hospital-area densification; YCD-adjacent operations under authorization.
Local property profile: Harbour-city mix of heritage districts, mid-century suburbs, and rapid hospital-area densification.
Ground conditions: 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.

How the Nanaimo survey runs
- 1
Network mapping
Routing drawings and operating temperatures define the loop. Where drawings are stale, the first flight itself recovers the true alignment — buried hot lines trace themselves thermally.
- 2
Contrast-window flight
Flown on cool evenings when the ground has shed solar gain: supply and return lines appear as clean linear signatures, and anomalies — hot spots, plumes, lateral spread — stand out against them.
- 3
Anomaly classification
Uniform warmth is normal line loss. Localised intensity, asymmetric spread, or surface wetness signatures are classified as insulation failure or active leakage and ranked by severity.
- 4
Dig-sheet report
Each actionable anomaly delivered with RTK coordinates, thermal evidence, and severity ranking — the document your mechanical contractor digs from, first time, right spot.
Nanaimo questions, answered
How well does thermal imaging work on buried heating lines?
It is the single best application of aerial thermography on buried utilities. A line running 60–120 °C under a metre of soil produces a clear, continuous surface signature in the right window — and a breach or failed insulation section produces an unmistakable local intensification. We routinely recover the routing of loops whose drawings were lost decades ago, then rank every anomaly along them.
What does a leak cost a district energy operator compared to this survey?
A buried heat-loop leak wastes treated, chemically dosed, heated water continuously — energy, make-up water, and treatment, around the clock. Operators typically find a single confirmed leak repays the survey many times over within a season, before counting the avoided excavation of wrong-spot exploratory digs.
When should campuses fly this survey?
Late fall through early spring, on cool, dry evenings — peak season for both thermal contrast and heating load. An annual flight in the same conditions builds a year-over-year baseline, so the question shifts from 'do we have leaks?' to 'what changed since last year?' — the cheapest maintenance posture there is.
Can you legally fly drone leak surveys in Nanaimo?
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.
How do Nanaimo ground conditions affect what the survey reads?
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.
What does district energy & buried heat loop survey cost in Nanaimo?
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.
