Abstract
A system comprises a facility for which snow is used, a snow producing unit for producing snow from water, and a collection section for collecting meltwater and supplies the collected meltwater to the snow producing unit as water used for producing snow. According to such a system, since snow is again produced from meltwater and used, artificial snow can be supplied to a facility for which artificial snow is used without using a large amount of water.
