PURPOSE:To treat waste soil liquid at low cost by a method in which a treating tank having a netted surrounding wall and openings on its upside and downside is set on the ground, and waste soil liquid is supplied to the treating tank for natural dewatering. CONSTITUTION:A dewatering tank A having openings it upside and downside is formed by forming an outer frame 1a of a channel part and by attaching a punched metal 1b and an expanded metal 1c only to the four-surrounding faces of the inside. The tank A is set on the ground of the construction site where waste oil liquid is produced and drain pits 6 are provided around the tank A. Excess waste soil liquid is orderly supplied to the tank A for natural dewatering. Afterwards, dewatered soil lumps (a) are taken out of the tank A. The waste soil liquid can thus be disposed at low cost.
