ABSTRACT:
A method for cleaning waste collection systems of solid materials using normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from a collection point in the waste collection system up to a pressurized container where the water content of the slurry is decanted and reused as injection water while the particulate material settles to the bottom of the pressurized container. When the container is filled with solid material it may be removed for emptying at a waste dump.
