Abstract: A unitary or modular, pre-cast, drive-down pit system suitable for use in a heavy equipment wash installation. The completed pit collects runoff generated by the washing of heavy equipment such as construction, industrial, farming, or road-building equipment. The pre-cast concrete separation unit and separate wall sections have tongue and groove mating ends that facilitate assembling the pit and provide for sealing against leakage of water. The separation unit has up to four chambers: a primary solids collection section; a secondary solids settling chamber; a free oil separating section; and a pump water holding section.

Abstract: A unitary or modular, pre-cast, drive-down pit system suitable for use in a heavy equipment wash installation. The completed pit collects runoff generated by the washing of heavy equipment such as construction, industrial, farming, or road-building equipment. The pre-cast concrete separation unit and separate wall sections have tongue and groove mating ends that facilitate assembling the pit and provide for sealing against leakage of water. The wall sections have built-in rebar attachment and water block elements at an angle so as to provide for a strong and waterproof bond with the ramp floor. The ramp floor is concrete, poured after installation of the separation unit and the wall sections to complete the finished drive-down pit. The separation unit has up to four chambers: a primary solids collection section; a secondary solids settling chamber; a free oil separating section; and a pump water holding section.

Abstract: A foot mop includes a cover member configured and contoured to receive and overlay a substantial portion of a user's shoe sole. The cover member has an interior surface, an exterior surface and a continuous free edge that defines an opening. On the interior surface of the cover member are a plurality of peripherally disposed snaps adjacent the free edge for matably engaging snaps on an adhesive strip peripherally mounted about the shoe. The exterior surface of the cover member includes a sponge layer with a plurality of mop like fibers mounted thereover for absorbing liquids. The device also includes a wall mounted storage device for draining and collecting fluids adhering to the cover member.
