Reduction of water charges associated with the operation of mist equipment, etc.

As a part of measures against summer heat, the Water Bureau has installed and spread a “mist device” with a cooling effect in the city, and has an effort to protect the city and tourists visiting the city from the heat (social contribution business). In order to install mist equipment, management fee is required to maintain initial costs such as equipment and installation costs, as well as water charges, electricity charges and maintenance costs. The Water Works Bureau will reduce or exempt "water charges used for mist".
