To quickly supply a large quantity of water for living to a height by connecting the terminal end of a high pressure hose connected to the discharge side of plunger pumps to a hose of lower pressure resistance than the high pressure hose, and arranging it toward the height.

Two plunger pumps 1 sending water in a storage tank 2 provided on a low district or a piedmont to a height are provided side by side, and high pressure hoses 3, 3 are respectively connected to the discharge side of both pumps 1, 1. Next, the two high pressure hoses 3, 3 are arranged toward the height in parallel, the terminal ends are connected to one flexible super high pressure hose 4 through a connector, and it is arranged toward the height. Next, the terminal end of the super high pressure hose 4 IS connected to a high pressure hose 5, further the terminal end of the high pressure hose 5 is connected to a pressure hose 6 of lower pressure resistance than the high pressure hose 5, and it is arranged toward the desired height. In this case, two wire-braid reinforcing layers are arranged on the outer circumferential face of the high pressure hose 3, 5 and the outer face cover is covered with weatherproof rigid rubber. The number of the reinforcing layer of the super high pressure hose 4 is over four.
