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.
The method is disposing of a pumpable liquid waste comprising the steps of continuously and simultaneously (i) excavating earth to a depth of at least six feet from one region and (ii) transporting it to and depositing it at another region, and depositing liquid waste on the excavated earth after it has been deposited at said another region and while the porosity thereof is greater than that of the earth prior to excavation.

Claim 4
Independent Claim

A method of disposing of a pumpable liquid waste comprising the steps of causing an excavator to continuously excavate earth to a depth of at least six feet at one side of a trench and transporting the earth as it is excavated to and depositing it at the other side of the trench, and depositing liquid waste on the excavated earth after it has been deposited at said other side of the trench and while the porosity thereof is greater than that of the earth prior to excavation.
