Abstract
Abstract A containment structure for controlling flood water or spilled liquids comprising an elongated, triangular flexible container to be placed where needed to form a stable, water-tight barrier. The containment structure has a spout for introduction of water into the container, a front flap for anchoring the container, and has end pieces adapted to be used for sealing the end of the container against irregular objects or another container. A floating pump assembly can be provided for filling the container with flood waters.
