We conclude agreement about cooperation such as emergency patrol about public sewer facility at the time of disaster and emergency measures.

The Yokohama City Sewerage Management Cooperative and the Yokohama City Public Sewerage Manager have concluded an agreement in preparation for an earthquake disaster since 2001. On the other hand, in recent years, large-scale floods have occurred frequently due to large typhoons and heavy rains caused by linear precipitation zones, and there is a need to strengthen measures against flood damage. Therefore, with the aim of realizing the early restoration of sewerage functions even in the event of a disaster including storm and flood damage, we plan to strengthen the system that responds to all disasters.
