Apparatus for cleaning sewers

摘要

An apparatus and method for cleaning sewers of solid materials using normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from the bottom of the sewer 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.
