PROBLEM TO BE SOLVED: To rapidly feed drinking water in case of emergency, etc., by providing a truck with a pump or pumping up a raw water, a device for adding chlorine for disinfection of the raw water, a cleaning device and an ultraviolet rays irradiating device for sterilization of clean water. SOLUTION: On a movable truck, a pump 1 for pumping up a raw water such as water for fire fighting and water in a pool and a cleaning device 3 are arranged and a chlorine adding device 2 is disposed on the midway of a pipeline between the pump 1 for pumping up and the cleaning device 3. The cleaning device 3 is a cleaner consisting of three kinds of filter media and as the first layer, the second layer and the third layer, an ion exchanging body 6, an active carbon 7 and a hollow fiber membrane module 8 are respectively used. A low pressure mercury lamp is inserted into an outlet 9 of the treated water of the cleaning device 3 as an ultraviolet rays irradiating device 4 and the treated water discharged from this ultraviolet rays irradiating device 4 is used as a drinking water from a water supply tap. In addition, in this case, under a condition where a clean water tap is closed, a safety valve 5 is worked and the pumped-up raw water is returned to a raw water tank. |
