  The water storage tank 32 is an emergency water storage tank, is designed to be earthquake resistant, and is embedded in the ground in the site as shown in the figure. Moreover, since it is connected to the water pipe of normal water supply through the water supply valve 30 and daily water supply to the apartment is performed through the water storage tank 32, it is always replaced with new water. Specifically, a drinking water combined earthquake-resistant water tank (manufactured by JFE Engineering Co., Ltd.) can be used.

  In addition, an external building energy environment management system (BEMS) equipped with a generator (for example, a micro gas turbine) operable in an emergency for supplying electricity and hot water to the building and apartment 10 in an emergency. An emergency cogeneration unit 40 that can communicate with the control center 38 is provided. The emergency cogeneration unit 40 includes a heat exchanger 42 for heat recovery. The hot water heated by the heat exchanger 42 is used by the pump 44 and the valve 46 to supply hot water to the building / mansion 10 in an emergency.

  In the present embodiment, the drainage from each door of the building / condominium 10 is normally turned on and flows to the sewer, and the valve 50 is turned on in an emergency and flows to the drainage storage tank 60 according to the present invention. A valve 52 is provided.

  As shown in detail in FIG. 2, the drainage storage tank 60 includes a drainage inflow nozzle 61 connected to the valve 52 and a valve 48 for heating the drainage flowing in by the drainage inflow nozzle 61 to reduce moisture. In the event of an emergency that is turned on, the heat exchanger 62 in which hot water from the heat exchanger 42 of the cogeneration unit 40 flows in and out of the nozzle 63, and the odor of the evaporated vapor heated by the heat exchanger 62 is diffused into the atmosphere.
