What are water trucks used for?

15 May 2015
Water trucks are different from regular trucks in that they have special tank specifications

Water trucks are a vital part of mining and construction operations. Dust control, compaction, even fire prevention are among the uses of these powerful machines. Water trucks are different from regular trucks in that they have special tank specifications, custom chassis design and mounting apparatuses, and associated pumping equipment.


Water trucks come in a range of sizes and designs, with larger trucks able to haul as much as 36,000L. Some are even specially designed for mining applications and come with off-road tyres, safety equipment and are reinforced for stability over rugged terrain.

The spraying and filling capabilities also vary from truck to truck, depending on the purpose. For starters, filler pipes are typically mounted on the truck’s near side or via an opening on top of the tank. As for spaying capabilities, spray nozzles can be situated on the front, side and/or rear of the truck, and are typically controlled from inside the driver’s cab. There are also drip bars, hose reels, water cannons and more.


Dust Suppression: In Australia’s dry and dusty outback, dust control can be a real problem not least because it presents hazard to workers. Dust suppression is especially important when undertaking large-scale earthmoving operations such as in mining and civil construction works. In these cases, water trucks such as the Caterpillar 769Dare used to spray the dry earth and reduce billowing dust.

Compaction: Adding moisture to soil can make it easier to compact. That’s why you’ll often see water trucks and big roller compactors working together to compress the surface, making it smooth and even.

Fire Prevention: As most mining operations occur in extremely remote inland Australia, water trucks can also serve to prevent fires from spreading. Sometimes, commercial water trucks are called upon to support fire trucks in containing bush fires. Also, when weather conditions present a severe fire danger, these trucks may also be used to wet the area as a preventative measure.
