  • Patent number: 6390154
    Abstract: A portable levee system includes a bag having a preselected geometric shape. The bag is continuous in that it has a length at least equal to its width, and is preferably many times as long. A top portion of the bag is open for receiving fill material. A preferred geometric shape is a trapezoid. The bag is removably mounted to a dispenser and the dispenser dispenses the bag from a rear portion of the dispenser. A preferred dispenser is towed behind a tractor or truck and the bag is filled within the dispenser and deposited onto the ground. A method of providing a portable levee is taught wherein a levee is created in a fraction of the time required to build an equivalently-sized levee utilizing current emergency levee construction systems.
