KOEI DW is a company which split off from KOEI SETSUBI KOGYO CO. LTD, which was one of the major
plumbing contractors in Yamagata. Currently, there is no method for checking the condition of the pipes in detailwhen repairing the pipes, and thus unnecessary work would be performed. However, using services providedby KOEI DW made it possible for the condition inside the pipes to be ‘observed’ using robots which can beinserted into the pipes. These robots can identify locations which need to be repaired, eliminate unnecessarywork, and utilize resources effectively to reduce the cost. KOEI DW was awarded the grand prize of theTOHOKUDX Award sponsored by the Tohoku Bureau of Economy, Trade and Industry in November 2021.
