An apparatus for cleaning waste collection systems of solid materials. The apparatus is capable of cleaning waste systems in two known ways. First, a pumping method uses normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from a collection point 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. Second, a vacuum system may be used to move the slurry from the waste system to the waste container. The vacuum system creates a negative pressure differential, causing material to be pulled through a vacuum tube and into the waste container. When the container becomes substantially full of solid particles, it may be emptied at a dumpsite.
