PROBLEM TO BE SOLVED: To prevent environmental pollution without using gas, chemical and the like and defog a road at a low cost by sprinkling water from a water sprinkling nozzle to make a state close to natural rainfall, thereby adsorbing fog generated on the road to be eliminated. SOLUTION: A water storing tank 1 is buried under the ground of a road R, and water drops with a particle diameter of 1.52 mm is sprinkled from a sprinkling nozzle 6 through a supply mechanism 7 formed by a water feed pump and various valves by water drop distribution with a water content of 30 g/m to adsorb and eliminate fog on a road R. A fog detecting sensor 8 is provided on the road R to detect generation and extinction of fog, and the supply mechanism 7 is automatically controlled through a controller 9. The water storing tank 1 is supplied with city water and river water through a supply path 2, and the road R is made water permeable so that water on the road R is recovered in a water permeable receiver B by a collecting path 3, and drain in a side groove P is recovered through a filter 5 by a collecting path 4 to be collected in the water storing tank 1. Accordingly, gas and chemicals are not used to prevent environmental pollution and the road R can be defogged at a low cost.
