On Tuesday, November 19, EBARA held a site tour of the Kinugawa Upper Dam Collaboration Facility (hereinafter referred to as "this facility") for fourth-year students at Kinugawa Elementary School in Nikko City, Tochigi Prefecture. This facility is the only unusual facility in the country that adjusts the water volume of the two dams. Usually, we supply water stably to the fields and cities downstream of the dam. In the event of floods and droughts, we protect the town from flood damage by controlling the flow rate.
