Abstract: An above-ground containment system comprises a plurality of truss assemblies, a band coupled to the truss assemblies, and a flexible liner. The truss assemblies are disposed in an arrangement defining a storage area. The band is coupled to the truss assemblies and encircles the storage area, and tensionably maintains the tress assemblies in the desired position. The liner is coupled to the truss assemblies and includes a central portion covering a base of the storage area.
