Basics of hydrovac

Question 1

1. The Vac truck has a hydro line and a vacuum line…
2. the vac line is often remote controlled and an actual operator runs the high pressure water gun to make the hole/trench.
3. The operator must wear PPE.
4. The Temperature and pressure of the water can be adjusted and the water gun carves the soil out making a smooth sided excavation.

Answer 1

5. The vacuum runs simultaneously sucking up the “slurry” created by the water and soil being excavated. 6.The excavation stops once the utility is exposed and or the legal capacity of the truck has been reached. 7. The truck then leaves to dump the slurry in a pre-approved location or into storage to be taken to a disposal waste facility at another time. 8. If the hole is to remain open it must be covered and signed/flagged for safety reasons.

Answer 7

The Vac truck has a hydro line and a vacuum line…

the vac line is often remote controlled and an actual operator runs the high-pressure water gun to make the hole/trench.

The operator must wear PPE.

The temperature and pressure of the water can be adjusted and the water gun carves the soil out making a smooth-sided excavation.

he vacuum runs simultaneously sucking up the “slurry” created by the water and soil being excavated. The excavation stops once the utility is exposed and or the legal capacity of the truck has been reached.

The truck then leaves to dump the slurry in a pre-approved location or into storage to be taken to a disposal waste facility at another time.

If the hole is to remain open it must be covered and signed/flagged for safety reasons.
