INITIAL RESPONSE AND BUSINESS CONTINUITY IN THE EVENT OF FLOOD DAMAGE AT WATER SUPPLY FACILITY -CONSIDERATION FROM DISASTER CASES OF WATER SUPPLY FACILITIES CAUSED BY THE HEAVY RAIN EVENT OF JULY 2018

The heavy rain event of July 2018 caused several severe flood disasters and landslide disasters. Some water supply facilities were damaged and the water supply was interrupted. Since water supply became difficult at water facilities, they received support from other facilities and responded to temporary facilities. We conducted interview surveys on the affected water supply facilities and summarized the way of initial response and the business continuity in the event of inundated damage. In the event of flood damage or landslide damage, the procedure from the initial response to the resumption of recovery was organized, and proactive measures for achieving early recovery were proposed.
