The Self Emptying Vacuum Vessel is an apparatus for collecting and discharging solid and or liquid material. The system is used to transfer said material from an undesirable area to a more preferred location. The Self Emptying Vacuum Vessel comprises a containment vessel which collects said material by a vacuum means and a screw conveyor as a means for continuously expelling said material from said vessel. Continuous flow is insured into said vessel by a vacuum regulating means and out of same vessel by an anti-bridging means.
