This paper reports on the outline of snow-flowing (melting) facilities, their effects on snow removal, characteristics of operating with the cooperation of the local residents, and how snow melting gutters utilize locally available energy. A snow flowing gutter is a channel built under the road along the edge of the sidewalk wherein snow removed from the road is dumped and carried by water flowing in it. Where this gutter is constructed, the road is almost always free of snow. From the viewpoint of securing walking space, this is an effective facility. This system is a good example of snow removal activity operated in cooperation with citizens who dump snow. Since snow is dumped on a daily basis, snow removed from roadways is also dumped along with snow on sidewalks. Thus, this system provides road administrators with the great merit that they do not need to transport snow to dumping sites. Construction of new snow flowing gutters is difficult due to difficulty in securing water source for flowing snow and the limits of manual snow dumping. If a new snow transport system or mechanized snow dumping method is developed as a solution to these problems, it would be possible that snow transport system will be established as new social infrastructure.
