Abstract

PURPOSE: To prevent local permeance rise dependent upon temporary much supply to filter and always filter sewage uniformly, by forming the boundary between the conglomeratic layer and the covering earth layer of the trench groove type sewage disposal device into a concave.
CONSTITUTION: Tank 1 consisting of water unpermeable materials such as rubber and synthetic resin is put on the bottom of trench groove 2, and sand 3 is filled beyond this tank 1, and conglomeratic layer 4 and covering earth layer 7 are filled in order on this sand 3, and the boundary between conglomeratic layer 4 and covering earth layer 7 is formed into a convave, and the thickness of covering earth layer 7 between the upper face of the conglomeratic layer and water exhaust pipe 9 is made uniform approximately. Thus, since sewage is filtered back by covering earth layer 7 of the almost same thickness as conglomeratic layer 4 even if sewage is supplied much temporarily from pipe 5, local permeance rise is prevented.
