PROBLEM TO BE SOLVED: To provide a water suction device which has high discharge amount per unit time, and can efficiently drain water, even if only high pressure water is jetted into a water suction pipe.SOLUTION: A water suction device 1 is equipped with a water suction pipe 2 which has a water suction port 20 at one end, and immersed in water on at lease one end side; and a jet pipe 3 for jetting high pressure water into the water suction pipe 2. The jet pipe 3 has a jet port 30 for jetting the high pressure water, and the jet port 30 is disposed in a space on the one end side in the water suction pipe 2, so as to turn to the opposite side to the water suction port 20. |
