The BC One Call gap in Duncan
BC 1 Call marks public utilities to your property line — always request it, it's free. But every service inside the line is private and stays unmarked. That gap is where most utility strikes happen, and liability lands on whoever dug. This service closes the gap.
Locating conditions in Duncan
Ground: Duncan sits on Cowichan Valley alluvium — sands and silts with seasonal saturation. Summer scans reach well into the alluvium; winter saturation shortens range. Farm and First Nations lands carry generations of undocumented lines.
What's buried here: Compact heritage downtown, surrounding farm parcels, and valley acreages with legacy water systems.

How the Duncan locate works
- 1
Inventory the systems
Controllers, panels, and devices reveal what wires exist — gate operators, valves, cameras, lighting.
- 2
Tone each run
Direct-connection toning traces each wire precisely, even hair-thin irrigation control cable.
- 3
Sweep for orphans
Passive and radar passes catch abandoned and undocumented runs the inventory missed.
- 4
Mark and schedule
Marks colour-coded by class, with a wire schedule in the report tying each run to its system.
How to read the marks we leave
CSA/APWA uniform colour code. Standard practice: mechanical digging stays 60 cm clear of any mark; the last hand-width is exposed by hand or hydrovac.
Duncan questions, answered
Can you really trace irrigation controller wire?
Yes — multi-strand irrigation control cable tones cleanly from the controller. On larger properties we trace valve-by-valve, which doubles as documentation of which wire feeds which zone — information most owners have never had.
Why bother locating low-voltage before digging?
Because cutting it stops the project just the same: dead gate, blind cameras, drowned zone valves, and a fault-finding bill that exceeds the locate many times over. Low-voltage is cheap to locate and tedious to repair — easy math.
Do you find pet fence and lighting loops?
Yes — buried pet containment loops and 12 V landscape lighting runs tone like any other conductor. Both are shallow, everywhere, and shredded by edging and fence projects weekly across BC.
Can you identify a mystery wire we dug up?
Usually — toning it back to its source panel or controller identifies the system, and the report documents it for next time. Unknown wires get treated as live until proven otherwise.
Does BC One Call cover my Duncan property?
Only partially. BC 1 Call marks registered public utilities up to your property line — free, and you should always use it. Everything inside the line is private and unmarked: irrigation, gas runs to outbuildings, landscape lighting, old septic, abandoned services. Duncan's stock — compact heritage downtown, surrounding farm parcels, and valley acreages with legacy water systems. — is exactly where those private surprises accumulate. Private locating closes that gap before you dig.
How do Duncan ground conditions affect the locate?
Duncan sits on Cowichan Valley alluvium — sands and silts with seasonal saturation. Summer scans reach well into the alluvium; winter saturation shortens range. Farm and First Nations lands carry generations of undocumented lines. Where local conditions limit one technology, the survey leans on the others — EM tracing, sonde work, and acoustic methods — so the locate objective is met regardless of soil.
