ABSTRACT:
A method is provided which permits incorporating large quantities of pumpable liquid wastes in the form of sludges, slimes and slurries, in the surface of the earth. The method involves the steps of continuously excavating earth from one region and transporting it to and depositing it at another region and thereafter depositing the liquid waste on the earthen material. The earth is initially excavated to depths which substantially exceed the normal agricultural tillage depths, i.e. to depths of the order of at least six feet, by digging the earth from one side of a trench and then transporting it and depositing it at the other side of the trench after which the waste liquid is deposited on the earthen material so transported. This permits very large quantities of liquid waste to be incorporated in a relatively small surface area.
