Abstract: What is disclosed is a portable, modular, and dynamically sized and shaped, above-ground, industrial liquid-containment system. Typically, the system has an outer-containment perimeter and an inner-containment perimeter (a reservoir), thus providing two barriers for environmental protection. A reservoir is comprised of a plurality of substantially A-framed segments that are hinged at the top and allows for folding together when the center and bottom braces are removed. A key feature for the A-frame segments is in their lack of steel cladding on the water side of most A-frames segments. Instead, fabric and/or cargo netting is used because it reduces weight and grips the A-frame purlins as the weight of contained liquids exert stabilizing downward force on A-frames. In addition, a steel grid system can run along the reservoir floor to compensate for expansion forces due to both temperature and water-weight.

Abstract: A portable, modular, and dynamically sized and shaped, above-ground, industrial-liquid-containment system is disclosed. In an exemplary embodiment, the system includes a plurality of elongated curbs, each of which has a substantially inverted-V-shaped cross-section. In variations, each curb can have a flat top surface, from which two walls extend downwardly at a predetermined angle. At the bottom of each of the curb walls, is a foot surface extending substantially parallel to the ground and to the flat top surface. The plurality of curbs are detachably coupled together to define a perimeter for a liquid-containment area. The height of the curbed boundary can be increased by installing curb-height extender members onto the first-layer of curb members. The defined containment-area floor and the plurality of curbs is continuously covered by liquid-impermeable sheeting in order to prevent leakage into the outer-ground environment.
