Abstract: A modular berm system and method for installing the berm system about a containment area are provided. The berm system is formed by interconnecting a plurality of panels in an end-to-end arrangement. Corner pieces which enhance the modularity, stability and rigidity of the berm system are also provided. A continuous liquid barrier liner overlies the containment area and the supporting perimeter of panels. The liner blocks any discontinuities between panels. Discontinuities can be overlapped with flaps for protection of the liner.

Abstract: A storage tank system stores liquid containing debris. The sidewalls of the tank have a curved lower portion for receiving debris settling out of the liquid and for directing at least some of the debris to a base of the tank. The tank is also provided with a plurality of nozzles spaced longitudinally along the curved lower portion the sidewalls for directing flush liquid downwardly against the curved lower portion for flushing any residual debris remaining thereon towards the bottom of the tank. The tank has a skid equipped with rollers for improved manoeuvrability in a berm environment and manifolds for improved interconnectability with other tanks.
