PURPOSE: A water level alarm collecting tank of a vacuum suction vehicle is provided to separate a sensor unit and an operating unit for complementarity and to efficiently intercept excessive filth by electrically operating a valve. CONSTITUTION: A water level alarm collecting tank in a vacuum suction vehicle moves sludge or filth with the suction force of a vacuum pump and contains a suction hose(1) connected to a body(2). The sludge or the filth is moved to the body through the suction hose. Then, the sludge or the filth floats along an electromagnet bar(30). A float(32) vertically moved by height adjusters(34, 36) and a sensor unit(20) with a sensor(38), sense the amount of the sludge or the filth. When the sludge or the filth is filled up to a setting level, a keystone valve(40) stops an air discharge hole(42) by the operation of the sensor so that the sludge or the filth is no more flowed.
