Hydro excavation is also called potholing, vacuum excavation, soft digging or hydro-trenching. The process involved in hydro excavation uses high pressured air or water and a vacuum supply to eliminate the objects or materials. It is the safest way to expose underground utilities or other buried structures.
Hydro excavation is a non-injurious and controlled procedure of excavating and removing soil that does not use any mechanical mechanism or tool. The water and soil suspension are carried to a debris tank mounted on a truck by a tube 8 inches in diameter and is powered by high pressured air or water. This procedure is a rapid, accurate and clean process which produces a reduced amount of backfill, less labor, not as much restoration and fewer negative environmental effects over traditional digging techniques. It is the controlled stream of water that accounts for a very accurate process that will only remove the materials required for inspection and repair.

The Hydro Excavator
A hydro excavator is a totally self-contained item which has several parts or units. The total package is necessary to be able to supply the most competent service.
- Vacuum excavator or suction excavator – This is a construction truck that takes out the soil from an opening in the earth. It eliminates heavy rubbish or trash from the land from several places by a strong suction via a large suction pipe which is around 1 foot in diameter. The speed of the air suction is around 100meters per second or 224 mph.
- Suction nozzle – A suction nozzle has two handles for the technician to hold. The handles could be placed on the collar that is swiveled or spun to expose a suction-discharge aperture. There are grilles covering the opening to let the suction nozzle release items it has hoisted that could be too large to enter the tube.
- The tip of the tube – The tip of the tube is usually equipped with teeth to incise the soil when it is used to dig.
- Compressed air and Water jets – Compressed air and water jets are used to loosen or move rocks and soil that are deposited into a rubble tank. The rubble will be disposed later or used to back-fill the hole made in the ground.
Other Uses of Hydro Excavators
- To expose on a large–scale buried utility systems rapidly and safely.
- To rapidly clean under and over utilities which would be scraped by hand if a hydro excavator is not used. With the hydro excavator, the resulting excavation is cleaner, safer and neater.
- Fast trenching work can be done with a hydro-excavator. The trenches created on landscaped fields and through underground utilities are neat and clean and will need very little restoration compared to other digging methods.
