Abstract

PURPOSE: To ensure cost reduction by eliminating a water pressure difference by providing a impermeable membrane that separates a seawater section from a fresh water section and can be moved up and down in a water tank surrounded by an external revetment wall and furnished with seawater passing holes, provided in coastal seawater. CONSTITUTION: The reservoir surrounded by an external revetment wall 1 is formed in seawater Ws, and seawater passing holes 2 are provided in the lower portion of the wall 1. A grit chamber 17 communicating with a rainwater introduction route 3 to introduce fresh water Wp such as rainwater and the first, second and third water storage tanks 7, 8 and 10 are provided. An impermeable membrane that separates vertically seawater Ws from fresh water Wp is provided in the tank 7 or the like. When a lot of both kinds of water from the ground is involved, fresh water Wp above the membrane 14 pushes down seawater Ws below through the membrane, and if freshwater Wp decreases, seawater Ws is flowed into the hole 2, equalizing the water level of the tank with the seawater level outside the tank. Therefore, equipment cost can be reduced by reducing the thickness of the wall 1.
