An irrigation system for supplying water to land (4), which is to be cultivated, through main pipe (3) and diversion pipes. The upper end of pipe (3) is arranged to a water supply located higher than the land which is to be cultivated. The diversion pipes are buried under the ground reaching to the cultivated land (14) and the end part of the main line is blockaded so as to utilize normal hydraulic pressure to supply the water to the cultivated land. |
