Hydrovac trucks keep digging through an Okanagan winter by heating the water they cut with, which breaks through frozen ground that stops a backhoe, and by winterizing their pumps, water lines and air systems so nothing freezes on the job. That keeps utility locates, repairs and emergency digs moving all year.
Why winter excavation is harder
Okanagan winters are milder than much of Canada, but the ground still freezes. Frozen soil is hard to cut, snow hides locate marks and site hazards, and short days and cold snaps squeeze the working window. Planning for those conditions keeps a winter job on schedule.
How heated water cuts frozen ground
D&L Environmental runs modern hydrovac trucks built for cold weather. Powerful coil heaters warm the water we cut with, and operators adjust the temperature and pressure to suit the ground, so we can work through the frost to the depth your job needs. The vacuum lifts the thawed soil and water into the debris tank as we go, leaving a clean excavation.
Frozen ground takes longer to cut than thawed soil, so a hole that’s quick in July can take longer in January. Build that into your schedule.
How we winterize our trucks
- Insulated, heated water lines connected to a heater near the pump cabinet
- Lubricating and winterizing procedures that operators are trained to follow
- Antifreeze, so units don’t go out of commission in the field
- Air tanks drained several times a day so they can’t freeze
- Good winter tires, with chains added when conditions call for them
- Trucks started about half an hour before heading out, so the engine and systems are warm
In extreme cold, our operators are trained to warm up in the cab at regular intervals, so we can work long shifts without putting the crew’s safety at risk.
Planning a winter dig: a checklist
- Allow extra time. Frost slows cutting, and the colder the stretch, the deeper the frost.
- Watch the forecast. Leave room in the schedule to move work around a hard cold snap.
- Clear access. Plow and sand a route for the truck, and clear snow from the dig area so the crew can see the ground.
- Protect the locate marks. Snow covers paint, so ask for flags or stakes. If you can’t find the marks, ask the owner or the locate service for a re-mark before anyone digs.
- Plan for short days. Arrange lighting if the work will run past dark.
- Protect open holes. Cover or barricade them so they don’t fill with snow or refreeze, and so no one steps into one hidden under fresh snow.
No frozen spoil piles
Machine digging in winter leaves a pile of spoil beside the hole that freezes solid overnight, which makes backfilling slow and messy. With a hydrovac, the loosened soil and water go straight into the truck’s debris tank and are hauled away, so the site stays clear. When it’s time to backfill, use the material the project specifies rather than trying to break up frozen chunks.
Emergency digs in the cold
Water main breaks and gas leaks don’t wait for spring. Our emergency line is answered 24/7, so a winterized hydrovac can be on its way when a line fails in the middle of a cold snap, and heated water means the crew can expose the line even when the ground is frozen hard.
What winter hydrovac is used for
Winter doesn’t stop utility work. We daylight lines before repairs and new installs, dig emergency excavations for broken water and gas lines, and keep HDD and construction sites clear of slurry. Read more about hydrovac daylighting, or see our guide to hydrovac excavation.
Winter hydrovac from D&L Environmental
With the right equipment, precautions and a little extra maintenance, our trucks keep working through the coldest months. D&L Environmental has more than 35 years of hydrovac and vacuum truck experience, two full-time heavy-duty mechanics who keep the fleet ready for winter, and 24/7 emergency response. We work from Kamloops and Merritt through the Okanagan and take hydrovac work across British Columbia.

Don’t guess. Ask the owner or the locate service for a re-mark, or for flags and stakes that stand above the snow, before anyone digs.
