[0007]

[Action]

 In the water storage device according to the present invention, rainwater that falls on the roof of the building is collected and poured into the lower part of the uppermost water tank. When the uppermost water tank is almost full, the surplus water of the uppermost water tank is poured from the upper part of the uppermost water tank to the lower part of the water tank immediately below. When the water storage tank directly below the water storage tank is almost full, the surplus water is injected into the lower part of the water storage tank below the upper part of the water storage tank directly below the water storage tank. After that, similarly, the surplus water in the upper storage tank is sequentially injected into the lower portion of the lower storage tank from the upper portion. Excess water in the bottom water tank is drained from the upper part to the outside of the building through the drainage system of the building. Rainwater is injected into the lower part of each water tank, and surplus water is supplied to or drained from the upper water tank to the lower water tank. Will be replaced automatically. Users of the water tank on each floor may use the water in the water tank for watering plants and the like during normal times. In this case, the user may replenish the water tank with tap water or the like, but if the water is not replenished, the water tank is automatically replenished with rainwater at the next rainfall.

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 indicates a building having multiple floors. The building 1 in the example shown in FIGS. 1 and 2 is a 5-story condominium, and has a flat roof as the roof 3. Water storage tanks 7a to 7e are arranged on balconies or balconies 5a to 5e on each floor of the building 1. These water tanks 7a to 7e may be directly attached to the floors of the verandas or balconies 5a to 5e (FIGS. 1 and 2), but may be attached to the walls of the building 1 on the verandas or balcony 5a to 5e. Good (Figure 3). Further, in order to secure an evacuation passage for the veranda or balconies 5a to 5e on each floor in an emergency, it is desirable that each of the water storage tanks 7a to 7e has a relatively thin shape and a vertically long shape.
