Abstract

A liquid containment apparatus which has an automatically resilient, collapsible wall whereby vehicles can drive into and out of the apparatus. The side walls are supported by brace members having a generally vertically oriented upper member joined by a resistance-type hinge to a base member, such that the upper member can be flexed in either an outward or inward direction. The upper members preferably support the side walls such that they lean inwardly, and preferably the brace members are removable.
