If you have liquid, sludge or slurry to relocate to a disposal site, you will most likely use a vacuum truck or tanker. Equipped with a pump and a tank, these vehicles can come with an assortment of attachments and may have the ability to be equipped with a high-pressure pump. Vacuum trucks also can be used to expose underground utilities: the ground is jetted with water, which is then sucked up by the vacuum, exposing the buried utility without the risks associated with using heavy digging equipment (backhoes, excavators, etc.) Vacuum trucks are often used by municipalities, governments and commercial businesses and have capacities ranging from a few hundred gallons to several thousand gallons. Vacuum trucks are regularly used to service septic systems, airplanes, sewer systems and mining sites. Popular manufacturers of vacuum trucks include Caterpillar, Ditch Witch, Ford, Freightliner, Hino, International, Kenworth, Mack, Mercedes-Benz, Sterling, Volvo and Western Star.
