Hydro vac excavation is a mechanical means of using water to break up earth, simultaneously removed by a powerful vacuum. When utilized properly the method is a safe, non destructive means of excavation. Super Sucker Hydro Vac personnel are extensively trained in safe practice procedures and are equipped with the tools to enable safe excavation.

As the underground distribution network becomes increasing complex the cost to employ a hydro-vac is extremely affordable when compared to hydraulic equipment and the potential for fatalities, cost to repair damaged plant and possible fines to recover loss of service. Hydro vac excavation is a proven method that, to date, has not incurred injuries, utility damage or loss of service.

In general, hydro vac excavations either expose a utility or remove earth in close proximity to a utility. An example of exposing the utility would be daylighting or potholing a gas main to determine its exact vertical and horizontal position, also known as Quality Level A in the field of Subsurface Utility Engineering. An example of the second general use of hydro vaccing would be an excavation for a pole installation that is within one meter of an existing utility.When excavating in the proximity of buried utilities, hydro vaccing is a safe alternative to hydraulic methods and an efficient alternative to hand digging.
