Drainage from various drainage sources (hereinafter referred to as drainage equipment etc.) such as toilets, bathtubs, washing machine pans, etc. on each floor of medium- and high-rise buildings, etc., has traditionally used the slope of indoor drainage branch pipes in the underfloor space Natural flow method (gravity drainage method) was common (for example, see Patent Document 1)
. However, the height of the underfloor space is only the minimum height required for maintenance due to restrictions on the structure of the building, and the height of the underfloor space increases as the distance from the indoor drainage pipe or drainage tract increases. The slope of the indoor drainage branch becomes gentle due to restrictions. Therefore, the installation position of the drainage equipment and the like is inevitably limited to a position near the indoor drainage pipe or drainage basin where the indoor drainage branch pipe connected to the drainage equipment and the like can secure a prescribed water guiding gradient. . In recent years, there has been a movement in the construction industry to renovate used office buildings that have been oversupplied and convert them into condominiums. In such a case, the internal structure of the existing building is used as it is, and the internal walls and the drainage equipment arrangement are modified so as to be suitable for living. However, in the case of condominiums (condominiums), unlike office buildings, drainage equipment and the like must be provided for each door, and for the reasons described above, it is desirable to install indoor drainage pipes or drainage basins at suitable locations. It is where However, although the wall can be repaired relatively easily, the change in the arrangement and expansion of the indoor drainage pipe or drainage basin is a major change accompanied by a change in the structure of the skeleton, making it difficult work. It is difficult to renovate the equipment corresponding to the drainage equipment.

Therefore, instead of the conventional natural flow method (gravity drainage method) using an inclined gradient, a kind of forced transfer method called a drainage pumping method is being used. In this drainage pumping system, drained sewage from each drainage source is temporarily stored in a large-capacity tank called a storage tank that houses the drainage pump, and this stored sewage is driven into the indoor drain branch pipe by driving the drainage pump. (For example, refer to Patent Document 2). However, it is difficult to secure storage space for each house in condominiums (condominiums), and it is necessary to lift the drainage pump from the storage tank where sewage is accumulated when the drainage pump fails or is inspected. Not only is there a problem in maintainability, but also the amenity of an apartment (apartment house) is significantly deteriorated due to leakage of sewage and the spread of odor.
