We exhaust various dirty water (life waste water from miscellaneous sources) in everyday life such as kitchen and bath, washing.
River and the sea become dirty when we discharge this life waste water from miscellaneous sources as non-processing.
In facility handling life waste water from miscellaneous sources from home, there is septic tank (merger processing septic tank) processing at each home other than the public sewer and agriculture fishing communities drainage facility.
In area without plans such as the public sewers, we install septic tank and clean life waste water from miscellaneous sources, and let's discharge.
With septic tank (merger processing septic tank)
Merger processing septic tank matches human waste with life waste water from miscellaneous sources such as kitchen and bath, washing using function of microbe and processes.
We can install septic tank in space for about one car, and, as for the water after processing, it is about a one-tenth of dirt before processing.
There is independent processing septic tank processing only human waste to septic tank other than merger processing septic tank, but life waste water from miscellaneous sources discharges into rivers as non-processing with this septic tank.
Where processing septic tank is installed in alone will change to merger processing septic tank.
(as a general rule, new setting of processing septic tank is not accepted alone from 2001.)

Attention by daily life when we use septic tank
We disintegrate, and septic tank purifies dirt of water by microbe. We are careful about next, and let's use septic tank to make environment where microbe is easy to act on.
(1) Water of restroom plays enough quantity.
(2) We do not use drug influencing microbe for toilet cleaning.
(3) We do not drain thing except toilet paper into restroom.
(4) We do not drain vegetable paring and tempura oil from kitchen.
(5) We do not cut power supply of septic tank
(6) We close cover properly without putting thing on the manhole
