PROBLEM TO BE SOLVED: To provide a water feeding system capable of efficiently and easily feeding water to vegetation or the like provided on a concrete base, such as on the rooftop of a building or a veranda part. SOLUTION: A water-impervious sheet 12, drainers 14, and a water-permeable sheet 16 are laid on the concrete base 10 and water-pumping blocks 18 are arranged thereon. Part of the water-permeable sheet 16 is connected to a water source and water supplied therefrom is allowed to diffuse and penetrate through the sheet by capillary phenomenon. Extra water on the water-permeable sheet 16 is collected by the drainers 14 and the collected water is absorbed by the part 22 of the water-permeable sheet 16 hanging into a clearance 20 between the drainers 14 and is again introduced into the water-permeable sheet 16. Water can be quickly diffused by use of the drainers 14 and can be quickly and evenly fed to even places distant from the water source. |
