Rural Chofu flooding cause the pump did not move for 10 hours October 17th 13:23
In Ota Ward, where the Tama River overflowed due to the impact of Typhoon No. 19 and flooded damage to houses, etc., all drainage pumps could not be moved for about 10 hours from 7pm on the 12th when the typhoon was approaching. I understood that. Ota-ku explains, “The evacuation instruction was issued and the staff on site had to be evacuated.”
Due to the impact of Typhoon No. 19, water overflowed from the Tama River and Maruko River in Tokyo and Ota Ward, and flood damage on the floor and under the floor was confirmed in about 590 cases near Denenchofu 4-chome and 5-chome.
According to Ota Ward, drainage work started using emergency drain pumps and pump cars around 5pm on the 12th with the approach of the typhoon, and a sluice gate to prevent backflow from the Tama River around 6pm. Closed.
However, because Ota Ward was instructed to evacuate Ota Ward at the time of the typhoon approach at 7:00 pm, the staff was evacuated from the site, and all the drainage pumps were unable to move.
After that, the sluice was opened around 5am on the 13th and the drainage work was resumed. However, a large amount of water was flowing into the residential area while drainage was not possible for 10 hours.
Ota Ward said, “The staff were in charge of drainage activities with the residents' safety first, but they were forced to evacuate to ensure safety because they were instructed to evacuate. In the future, I would like to discuss with the facility manager, the Tokyo Metropolitan Sewerage Bureau and related organizations, so that continuous drainage activities can be conducted. "
A 67-year-old woman living in Ota-ku, Denenchofu 5-chome, said that the drainage pump could not be moved for about 10 hours. However, the residents around here know that the Maruko River overflows when the sluice is closed, which is why I wanted to provide information as soon as the sluice was closed. ”
