In Wakayama City, water was found leaking from an underground water pipe on the 8th of this month, and the city has decided to repair it.
Because it is necessary to completely stop the flowing water during construction, the water supply will be cut off in a wide area in the city from 10 o'clock on the 19th, and according to the city, about 35,000 units, one fifth of the city, according to the city. Water can no longer be used.
In Wakayama City, three evacuation centers have been opened outside of the water supply cutoff area, and water stations will be set up in 30 places including elementary and junior high schools and parks from the morning of the 20th.
It is said that the cutoff is scheduled until 10 pm on 22nd of this month, but depending on the situation of the place where the water is leaking, the scale of the cutoff may be smaller or the cutoff period may be shorter. It is to say that there is.
A man from a 40-year-old office worker living in the city said, "I escaped running out of water, but I was very anxious because my friends and acquaintances cut off. I feel the importance of storing water regularly." I was talking.
Water pipe laid nearly 60 years ago
There is a reason that Wakayama City decided to cut off the water so far this time.
It was because the leaking water pipe was considered to be the main line.
According to the city, the water pipe was laid about 60 years ago in 1962.
Wakayama City decided on a large-scale water cut because the damaged part was a large water pipe on the main line.
However, in the case where the pipe was actually dug during the construction work on the night of the 19th and the branch was a narrow water pipe, the scale and period of water cutoff may be shorter than planned.
According to the Wakayama City Board of Education, the 13 municipal elementary schools and three junior high schools are planning to reduce classes only in the morning for two days on the 20th and 21st due to the impact of water outages.

With the renewal of aging facilities, more than 20,000 water leaks and damages occur annually nationwide.
