Disaster Water Supply Station

Final update date: January 6, 2021

In Water Works Bureau City has developed a reservoir, an underground water tank for disasters, and an emergency water tap as a water station for disasters in order to provide emergency water to evacuation shelter gather for emergency water supply. In case of emergency, let's confirm familiar water station with evacuation shelter in case of emergency.

Reservoir: 22 locations

This facility distributes drinking water made at the water purification plant to each household.
During an earthquake disaster, approximately 190,000 cubic meters of drinking water can be secured, equivalent to what citizens need for a week, and Water Works Bureau drinking water equivalent to the amount that citizens need for one week.
water vehicle ※It is also used as a place to replenish water.
Reservoirs that are ready for water supply will be announced on the banner.
※water vehicle puts water in reservoir and supplies water preferentially in disaster medical base hospitals.

Underground water tank for disaster: 134 units

The underground water supply tank for disasters has been developed so that drinking water can be secured within a radius of approximately one kilometer in total, including reservoirs, and has been installed in elementary and junior high schools such as evacuation shelter along with the reservoir.
This is an underground water tank where tap water flows as part of a normal water pipe. When the water pressure drops, the inflow and outflow valves close, and the drinking water is stored.
For about three days after the disaster, local residents can install temporary faucets and supply water.
In addition, Yokohama-shi pipe construction cooperative assists establishment.
A "sign" is installed where there is an underground water tank for disasters.

In the event of a disaster, this facility installs a temporary water supply device on a pipe that is resistant to earthquakes and supplies water.
Water Works Bureau City staff will install temporary faucets sequentially with the Yokohama City Pipe Works Cooperative based on the water outage situation after the fourth day of the disaster.
Emergency hydrants prepared for water supply will be notified by "Nobori".

Seismic hydrants: 12 locations (total of 48 locations will be installed by 2023)

Seismic water taps are installed in evacuation shelter City, where facilities such as underground water tanks for disasters and school water tanks are not installed.
We are working to make emergency water supply possible by making the water pipe from the water pipe to the outdoor drinking fountain earthquake-resistant, and the installation of all 48 locations is scheduled to be completed by 2023.
A "signboard" is installed where there is an earthquake-resistant hydrant.
