In Yokohama City, water is supplied by a water distribution block system that divides the city into 25 districts, and each block has a reservoir and a pumping station. The reservoir can store about half of the amount of tap water used a day, and can respond to a sudden increase in usage. In addition, the pump station adjusts the amount of water and water pressure by following the pump according to the amount used, and supplies water to citizens stably.
In order to respond appropriately to such changes in water volume, we monitor these controls in the management room of the water purification plant 24 hours a day, 365 days a year, and strive for stable water supply.
