Tokyo Metropolitan Government develops unique model for flood disaster management

Updated:4 years, 7 months ago

Tokyo (Japan), Nov 26 (ANI): Tokyo is a densely populated city. It has unique flood control facilities that help prevent rainwater disasters. To prevent flooding during the rainy season, there is a huge underground water storage facility in the city. “Wada Yayoi Trunk Sewer” is one of the largest rainwater storage lines in Japan. It is a huge storage facility with an inner diameter of 8.5 meters, a length of 2.2 kilometres and a storage capacity of 150,000 tons. To prevent noise from falling energy, the system also uses a "drop shaft" that rotates and drops water to the bottom so that it does not damage the facility’s power. This is a model of “Wada Yayoi Trunk Sewer”. In times of heavy rainfall, the river rises and flows into the sewers to prevent flooding. On “Wada Yayoi Trunk Sewer”, water is poured into the reservoir to prevent disaster. The "drop shaft" method allows water to move smoothly. Tokyo's sewage system is prepared in a way that prevents all kinds of rainwater disasters and guarantees life safety to the citizens.
