ABSTRACT:
The invention provides a method for washing an article and collecting the used wash water as well as a wash pad and a mobile apparatus. A wash truck is modified to include a water treatment unit and a submersible pump for removing used wash water from a water-proof surface, such as pavement or the wash pad. The used wash water is subsequently recycled and reused or disposed of without harm to the environment. The wash pad includes a bottom sheet and a containment wall that together define a containment area for containing the used wash water. A secondary containment area may be defined for wash pads that are used for the washing of vehicles. The wash pad may be rolled for storage upon a reel mounted to the wash truck. Other embodiments provide wash pads for use in washing rail-mounted articles, and the interiors of trailers and shipping containers.
