Construction and mining sites kick up a lot of dust that would impede progress without water trucks with 2,000-4,000-gallon tanks that tamp down dust very efficiently by following a grading equipment that is leveling and preparing soil for work. Dusty jobsites not only slow down work but increase health risks such as eye and lung irritation, bronchitis, asthma and heart disease, and by dampening dust, water trucks remove them from the air that miners and construction workers are breathing.http://www.tongyatrailer.com/sanitation-vehicle/water-truck/
