Abstract:
1. A modular waste water and hazardous chemical containment and collection system comprising: a) at least one modular pan having a planar bottom surface, a multitude of vertically disposed walls integrally attached to the planar bottom surface at bottom edges of said walls, a multitude of horizontally and outwardly disposed ledge members, one ledge member integrally attached to each vertically disposed wall at a top edge of each wall and a multitude of downwardly depending lips, one lip integrally attached to each ledge member at an outer edge of said lip; b) a horizontal plane of each modular pan defined by the pan planar bottom surface and the multitude of vertically disposed walls; c) a drainage waffle inserted within each of the at least one modular pan, the drainage waffle covering the pan horizontal plane and having a plurality of recesses and protuberances defined by a top surface, a bottom surface and upwardly angled walls connecting said top and bottom surfaces, the drainage waffle having a height; d) a work surface covering the top surface of the drainage waffle and having a plurality of liquid drainage holes formed throughout said work surface, said holes permitting liquids that contact said work surface to drain through said work surface and into an area of the modular pan containing the drainage waffle, the work surface having a thickness which when added to the height of the drainage waffle equals a height defined as the total height of layers, the total height of layers not exceeding the height of the multitude of vertically disposed walls; e) a means for withdrawing liquids from the at least one modular pan; f) a pump connected to said means for withdrawing liquids; g) a storage container connected to said pump for retaining liquids withdrawn by the pump and captured by the at least one modular pan; h) the at least one modular pan having four peripheral edges, two of the peripheral edges having a long length and two of the peripheral edges having a short length, the two long and the two short peripheral edges defining a rectangular shape for the at least one modular pan; i) one of the two long peripheral edges and one of the two short peripheral edges each having a first area disposed underneath the horizontally and outwardly disposed ledge members of each said long and short peripheral edge, the first area having a length defined as “x”, wherein “x” is the distance between an outer surface of the vertically disposed wall and an inner surface of the downwardly depending lip of each respective long and short peripheral edge, the peripheral edges having said first area length defined as “x” being narrow peripheral edges of said pan; and j) an other of the two long peripheral edges and an other of the two short peripheral edges each having a second area disposed underneath the horizontally and outwardly disposed ledge members of each said other long and short peripheral edge, the second area having a length defined as “x +y +z”, wherein “x” is the distance between the outer surface of the vertically disposed wall and the inner surface of the downwardly defending lip of each long and short narrow peripheral edge, “y” is a thickness of each vertically disposed wall and “z” is the thickness of each downwardly depending, the peripheral edges having said second area length defined as “x +y +z” being wide peripheral edges of said pan.
