What Does Holding Tank Mean?

A holding tank, as it pertains to hydro excavation, is a large capacity vessel used for receiving and storing debris removed from an excavated site. The holding tank, which is usually mounted on a truck, is then transported to another location where the collected waste material is either disposed of or treated.

A holding tank is also known as a vacuum tank or debris tank.


Trenchlesspedia Explains Holding Tank

The holding tank is part of the vacuum system used in hydro excavations. As high-pressure water excavates the surrounding soil, a suction hose (which is attached to the tank) removes the slurry material from the site and transports it to the holding tank.

Holding tanks are also used to store and transport other types of waste material including, but not limited to untreated sewage, industrial waste, slurries from animal waste, and other contaminated waste material.

Holding tanks are available in different capacities depending on the volume and type of debris being vacuumed at the site.
