A device for processing the residual water of a ship block is provided to increase the closure force of a cover and an outlet by opening the outlet to discharge the residual water at the right time. A device for processing the residual water of a ship block comprises a tank, a cover(120), an opening and closing switch(130), a drifting unit(140), a magnet sensor(150) and a controller(160). The tank is filled with the residual water(10) and has an outlet discharging the residual water. The outlet is controlled by the cover. The opening and closing switch opens and closes the outlet with the up down driving of the cover. The drifting unit is installed within the tank. The drifting unit comprises a drifting(141) and a magnet(142). The drifting is risen with the buoyancy of inside of the tank the residual water. The magnet is installed on the top of the drifting. The magnet sensor is installed on the top of the tank.
