Frequently Asked Questions about Hydro Vacuum Trucks

How does a vac truck work?

Our vac trucks use pressurised water to break up soil which is then removed through a vacuum system and deposited into a debris holding tank to be safely disposed of.

What size vac trucks do Provac have in their fleet?

At Provac we have a selection of vac trucks ranging from as little as 1000L trailer-mounted units to as big as 12,000L truck-mounted units. Our most commonly used truck size ranges between 5,000L – 8,000L units.

Will my job require non destructive digging with a vac truck?

Digging safely with a vac truck is highly recommended when underground utility services are present within the area of digging. If you're unsure what lays underneath the ground, you should always call Provac to locate and map the area out.

How long does it take to dig with a vac truck?

Depending on the job's scopes, it can sometimes be quicker, easier and safer to use a Vac truck to excavate. The type of ground can also affect the time it takes to dig with a vac truck. For example, it can be much quicker to dig in and trough sand instead of digging in and through a rocky subsurface.

How long is the vac truck hose and gerni wand?

Our Vac trucks are all equipped with a suction hose and gerni wand extensions. All of our trucks carry a minimum of 20m of extension hose but can carry up to a 60m of hose extension on board. Our gerni wands can be adjusted from 1.5m in length up to 3.0m.

How deep can you dig with a vac truck?

Depending on the type of ground you are digging in, one of our vac trucks can typically dig up to 3.5m deep. On some projects, our vac trucks are used to dig in holes that have been mechanically excavated and properly shored and benched for our operator's safety.

Can you dig a service trench to install new underground services?

Yes, our services are often called upon by electricians and plumbers, who are installing new pipes and cables. We have dug trenches for some of our electrical clients that have been 1m deep and up to 80-100m long.

Can you dig footings/post holes for fences and platforms?

Yes, we are often called upon by fencing and signage contractors to dig the footings for new fences and signs that need to be erected around other underground services.

Do you have a vac truck small enough to access tight areas?

Yes, we have a top of the range Vermeer trailer mounted unit with a 2000L holding capacity. This trailer unit is towed by a 4WD and is used to access properties and all the hard to reach places where a regular vac truck may not be able to reach.

Can you suck away sewer waste?

We deal with sewer waste on a case by case basis only. We can work safely around damaged sewer infrastructure, but we do not suck sewer slurry away from holding tanks and portable toilets.
