Small-scale onsite wastewater treatment system was proposed below a new thought. In other words, current type is oblong in a horizontal direction and the proposed type is lengthwise in a vertical direction. The proposed type may be called deep type. And the current type has one inflow mouth, but the proposed type has two inflow mouths. The nightsoil that is high density wastewater flows into tank for only nightsoil. The small-scale onsite wastewater treatment system planned below such thought was established in general home and was examined. Several experiments were carried out to find a way acting effectively for the inflow load changes and the experiment result was examined comparison. As a result when discharge was regulated in last settling tank, the good quality of the water provided. Water was turned over from last settling tank to anaerobic tank and flow regulation was carried out, but this way was equal with the current way.
