Abstract: The present invention relates to a fluid retention station for receiving a fluid that may be washed, flushed or drained from a vehicle and retaining the fluid. The station includes a plurality of layers for providing a floor to overlie existing terrain and includes at least a berm pad layer and a porous layer. The berm pad layer contains a floor and walls which provide a fluid tight enclosure. The porous layer overlays the berm bad layer and receives the fluid and allows the fluid to flow through to the berm pad layer. The porous layer removes any contaminants too large to pass through the porous layer or which have an affinity for a surface of the porous layer. A ground pad layer may also be used to underlie the berm pad layer. In addition, a track layer may be used to overlay a portion of the flooring to protect it from the vehicle or other equipment.

Abstract: A portable equipment wash station employing a retractable flooring system. The retractable flooring system typically utilizing three layers. The first pad being a ground cover layer which employs a heavy duty material suitable for protecting the other layers from the ground. The second pad being a berm pad which is constructed so as to incorporate containment walls along the perimeter of the pad. The containment walls serving to contain contaminated water and route such contaminated water to recycling, storage, or disposal as desired in the given application. The third pad being a track pad. The track pad employing a mesh material and track strips. The mesh material allowing for the flow of contaminated water through the track pad for containment in the berm pad. The track strips providing an area on which the tires or tracks of a vehicle or other equipment may be driven.
