News of firefighting water use facility setting subsidy grant system

Final update date March 3, 2020

In the event of a large-scale earthquake, fire hydrants may not be available due to damage to water pipes. For this reason, in addition to fire hydrants, various types of fire prevention water tanks, rivers, ponds, etc. that are effective for fire fighting are required.
In Yokohama City, we are systematically developing fire prevention water tanks, but since it is becoming increasingly difficult to secure land for installation, we have newly established the “Firefighting Water Use Facility Installation Subsidy Grant System” and started in April 2005. Started on the 1st.
For those who are planning to build a fire-resistant building that can install a water tank (underground water tank) that utilizes the foundation, please understand the fire prevention water tank maintenance business and use this system.

Maintenance area

The city is divided into 500-meter meshes, and the risk of fire spread is evaluated based on the non-combustible area ratio (inflammableness) in the mesh and the approximate wooden protection coverage ratio (the amount of combustible materials), and each mesh is ranked.
In addition, the “base water volume” (the amount of water required for each mesh) is determined for each rank, and maintenance is carried out for meshes where the total amount of existing fire-fighting water other than the fire hydrant owned by each mesh is less than this standard water volume To do.
We assume 149 mesh as maintenance area, but please confirm concrete place with Fire Bureau Security Division.
