ABSTRACT:
An environmentally safe concrete washout container employs one longitudinally extending side wall unit located on each side of the container. The side wall units assist in defining the space within the container for the collection of concrete waste, including concrete fluid washout material. Each side wall unit has an exterior wall and an interior wall, the walls forming a longitudinally extending open area. The internal walls have slotted openings at their upper and lower ends. Instead of spilling over the edge of the container, concrete fluid washout material which reaches a certain height within the space in the container flows through the upper slotted openings of the internal walls and then down into and through the open areas between the exterior and interior walls of the side wall units. The concrete fluid washout then flows through the lower slotted openings into an enclosed space or cofferdam, where it may be drained or pumped out of the container. In this manner, concrete fluid washout is recirculated back into and then out of the container, rather than being spilled onto the ground.
