Origin of "day of septic tank"

In commemoration of this, the Ministry of Health and Welfare, Ministry of the Environment, the Ministry of Construction (in those days) advocated from 1987, and October 1 was established every year with "day of septic tank". We assume this day opportunity and will think about domestic septic tank.



Type and function of septic tank

 Because septic tank cleans dirty water found at home using function of microbe, it is facilities which are important at all in protecting water regime of the earth. Well, do you know that there are "independent processing septic tank" and two kinds of "merger processing septic tank" to this septic tank? Which is septic tank of your home?



Independent processing septic tank

 We handle only drainage of restroom, and processing septic tank releases life waste water from miscellaneous sources (※) such as kitchen or washing, bath to river and the sea as non-processing alone. Therefore, much dirty water will just flow into river and the sea.

 ※ Life waste water from miscellaneous sources: We excluded drainage of restroom from drainage to be given from everyday life of ordinary household.



Merger processing septic tank

 Merger processing septic tank processes including life waste water from miscellaneous sources such as kitchen or washing, bath as well as water of restroom.
