We conducted a sounding-type market survey accompanying the renewal of existing fire prevention water tanks.

Final update date November 15, 2019

For establishment of "renewal business of existing fire prevention water tank", we carried out dialogue with private companies!

To establish a renewal business for existing fire prevention tanks, we conducted a “Sounding-type market survey” to widely hear ideas and know-how from private businesses.

<Implementation period>
From February 29, 2016 (Monday) to March 25, 2016 (Friday)
<Participation status>
6 business operators
<Result of Implementation>
In this dialogue, six companies participated and we were able to hold a dialogue.
Each company provided suggestions on construction methods and construction periods from a professional point of view, repair and repair methods inside the fire prevention water tank, and new renovation methods.
The issues facing the authorities are not only the problem of one part of the fire prevention water tank installed in a specific place, but also the future redevelopment of the fire prevention water tank with different installation conditions. And proposals were all helpful.
In the future, we will refer to the proposed construction methods for specific locations and promote the fire prevention water tank maintenance business.


Toward the Establishment of an Existing Fire Tank Renewal Project
Through dialogue with private business operators
"Sounding-type market research"

In Yokohama City, it will be time to renew (remain) existing public fire prevention water tanks that have been installed for more than 50 years in the future with the aim of securing water usage for large-scale disasters such as earthquakes. The installation status of the fire prevention water tank in Motoichi is difficult to secure a construction area for redevelopment (removal and new installation at the same place), and the cost is large.
Therefore, we conducted a “Sounding-type market survey” to widely listen to ideas and know-how that can be realized from private businesses regarding new redevelopment methods utilizing all or part of the skeleton. We would like to refer to the establishment of the method, so please join us.
