  The drainage channel forming tool used in the conventional drainage wastewater treatment device only closes the drainage channel formed by the groove portion of the groove forming base material by fitting or attaching the lid member to the groove forming base material. Therefore, when the flow rate per unit time of drainage drainage is temporarily increased or the drainage channel is clogged with foreign matter, the drainage drainage in the drainage channel is at the location where the groove forming base material and the lid member are aligned. There is a problem of leaking outside through a certain mounting surface.

  Moreover, since the drainage forming device of the drainage wastewater treatment device is arranged on the floor of a common corridor or a veranda of an apartment house, there is a possibility that external force is applied to the lid member by stepping on the drainage forming device or dropping an object. The external force at this time may cause damage to the lid member or the groove forming substrate.
