[Registered Business Operators] Businesses who have applied for registration of this system during the recruitment period of cooperating companies of the "Yokohama City Water Supply Safety and Security Partner (Materials Supply)" system (currently not recruiting)
[Contents of cooperation] In the event of an emergency, Water Works Bureau will request registered operators to cooperate in supplying necessary materials. In addition, for necessary materials, we will supply materials to the extent that we can supply them. (There is no obligation to cooperate in supply under this system.)
[Materials to be supplied] Distribution pipes, water supply pipes, fittings, water leakage prevention fittings, valves, etc.
[Main delivery locations] Water treatment plants, distribution reservoirs, Water Works Bureau Government Building, etc.

In Water Works Bureau, we are replacing aging water pipes with earthquake-resistant pipes, but the rate of seismic pipes throughout the city is not yet sufficient. Therefore, in the event of a disaster such as an earthquake, a lot of damage is expected to occur to the water pipe.
In order to quickly restore these, a large number of materials used when repairing water pipes are required.
