Definition - What does Vacuum System mean?
A vacuum system, as it pertains to hydro excavation, is the system responsible for transporting debris from the excavated site to a storage tank located on the vacuum truck. The vacuum system itself consists of a suction hose and a holding tank. The size of the hose and tank, as well as the suction power required, depends on the type and amount debris being removed from the site.

The vacuum system is the second, and most essential half of hydro excavating. As high-pressure water cuts through and excavates the soil, the suction hose simultaneously removes the slurry from the site into a holding tank to be transported and disposed of elsewhere. This system is especially beneficial in exposing underground utilities due to their efficient and non-destructive nature.
In addition to performing hydro excavations, vacuum systems are also commonly used to provide suction for the removal sewage, industrial liquids, and slurries from animal waste.
