Man has always been in a natural habitat. Since ages, man has taken from nature and stayed with nature and this nature has been the core to his existence. With the growth of civilizations, he started creating his own small world, though that world also existed in the nature. With development and growth, man started using more and more of nature to gain more profits and live happily. But while doing so, he forgot that nature has its own limitations. It cannot be used beyond a certain limit. Even the usage to that limit has certain restrictions. When individuals started setting up factories, they neglected the concern of air and water pollution. With phenomenal growth of such factories, the environment has been depleted to the extent that the world is now facing a severe problem of global warming. Thus, staying with nature and maintaining the natural balance is the most crucial requirement. It is not only a requirement for the sake of environment, but primarily it is a mandatory requirement for sustaining the human living on this earth.

A vacuum truck helps in fulfilling this objective of cleaning the pollutants and waste and maintaining the ecological balance. It is primarily a type of truck which has a huge tank loaded over it. This tank is a heavy duty truck which has a heavy vacuum system attached to itself. This truck has a suction pump attached to it which helps in pulling the waste and the polluting materials into the tank and de-loading it at a safe site. The suction pump used in such a truck is most often the rotary vane vacuum pump. This vacuum tank is specifically designed to load all solid or liquid waste and pollutants. It can also be used to dispose off sludge or slurry. This tank basically works on the concept of pneumatic science where a suction line with a diameter of 2€-4€ is used. Preferably, a suction line with a 3€ diameter along with a suction pump is used to load the solid and the liquid wastes pneumatically.

Such tanks find great use in a variety of industrial requirements. The local authorities can use such trucks to clean the sewers or the street. It can also be used to clean the septic systems and for cleaning up soil which is contaminated with pollutants. The companies involved in sanitation use this tank truck extensively to lift sanitary sewer wastes. The vacuum trucks also find an important requirement in many restaurants where it is used to lift the greasy wastes out of the grease interceptors. The petroleum mining and refining industry also widely uses this tank truck. This vacuum truck is used to clean the spills while petroleum drilling and is also used to clean the crude oil or other such storage tanks. In fact, these vacuum trucks are so important in the natural gas and oil drilling industry that such trucks are permanently stationed at the drilling site for cleaning and removing the spills, cement, drilling mud, brine water, drilling cuts and all such industrial waste and pollutants from the site. The trucks then off-load these wastes in the specified sump sites or in case the wastes are within considerable limits of pollution, they are dumped at farms and fields where farming is done.
