To provide a circulating equipment for water area which can reduce the running cost by suppressing the electric power consumption and mechanical loss to a lower level.

An air bubble pump 1 is constituted of water lifting pipes 2 which have perpendicular axes, water guiding pipes 3 which are disposed in communication with the lower sides of the water lifting pipes 2 and extend horizontally and an air ejection means 4 which ejects air for lifting into the water lifting pipes 2. This air bubble pump is installed in the water area 5 and the water in the water lifting pipes 2 is risen and drained by drive of an air supply source 41 of the air ejection means 4. The water in the water area 5 is sucked into the water guiding pipes 3 accompanying the drainage to generate a flow(f) heading toward the suction ports 3A of the water guiding pipes 3 in the water of the water area 5. The water of the water area 5 is circulated F by such flow(f) and the water of the water area is circulated by the continuing of the circulating flow F, to clean the water.
