A containment pond comprising: an impermeable membrane having a bottom, and continuous sides forming an open-top container. Each side is adapted with a loop of same impermeable membrane so as to form a sleeve longitudinal to all sides. Each side sleeve is adapted with primary and secondary forming members slidably engaged within each said sleeve. The two primary forming members facing each other have a length equal to its mating sleeve, and the two secondary forming members perpendicular to the primary members are each in two sections, divided at the center of their length. When the secondary forming members are pulled apart slightly from each other, the containment pond can be collapsed into a much smaller package by gathering the secondary center portion toward each other. Conversely, said pond can be erected in mere seconds by reversing the above.
