A collapsible containment vessel, preferably made from a suitable plastics material such as polyvinyl chloride is constructed from a bladder having a surrounding side wall, a top end and a closed bottom end. Inflation chamber means is positioned about and attached to at least one of an interior or exterior facing of the surrounding side wall and which extends from the bottom end to approximate the top end. A closable access port communicates with the inflation chamber means in order to facilitate the inflation and deflation of the chamber. When deflated, both the surrounding side walls of the bladder and inflation chamber are collapsed significantly reducing the volume of the containment vessel. When inflated, both the surrounding side wall of the bladder and the inflation means are rendered in a semi-rigid condition such that the bladder at its top end can be filled with liquid or solids material.
