A sewage tanker is installed on a large truck and is intended for providing widespread solutions for problems of blockages, cleaning boreholes and transporting effluents. The trucks on which the sewage tankers are installed have a high and strong power accumulation and pumping capability. The sewage tanker pumps at the highest pumping rating and, therefore, manages to solve complex problems quickly and easily. The sewage tanker pumps thousands of liters of liquids per
minute. The sewage tanker has an ability to execute two actions. On the one hand, the sewage tankers can pump water rapidly and, on the other hand, they can also inject water efficiently, by activating an especially high pressure. The sewage tankers’ ability to execute these two actions is a substantial advantage of the sewage tanker. Therefore, sewage trucks can be used for both clearing blockages and cleaning boreholes and transporting effluents.
