令和元年東日本台風通過後の首都圏外郭放水路

This video focuses on "Metropolitan Area Outer Underground Discharge Channel" ("Shutoken-Gaikaku-Hōsuiro") in Kasukabe City, Saitama Prefecture. This facility is a flood control facility to take water from five rivers and guide it to the Edogawa River when a flood occurs. As a downstream resident who is a beneficiary of this project, I am grateful and proud to have an underground dam like this facility in my neighborhood. See below for more information on how our facility worked during this flood. https://kasukabe.keizai.biz/headline/... https://www.sankei.com/affairs/news/1... https://www.fnn.jp/posts/00048550hdk/... https://kasukabe.keizai.biz/headline/...
