Abstract: An apparatus for the collection of wet concrete residue that results from rinsing of a concrete dispensing element of a concrete delivery vehicle. The apparatus includes a container body having an internal volume with an open top and a back wall and side wall, a shield guard that extends above a back and at least portions of the side walls of the container body, a containment cover that is hingedly attached to the container body and which permits the containment cover to open between a full opened position where the open top of the container body is accessible, and a fully closed position wherein the container cover water tightly closes the open top of the container body, a drain valve connected to the container body to control flow of liquid out of the container body, a strainer associated with the drain valve which prevents aggregate from being drained through the drain valve, and suspension hooks for suspending the apparatus on a concrete dispensing element of a concrete delivery vehicle.

Abstract: An apparatus which is useful in the separation of solids from a diluted, wet, concrete mixture has (a) a free-standing first container with a drain port and a top opening, (b) a strainer disposed within the first container, (c) a drain port shut-off valve, (d) a second container capable of providing a reservoir for recovered liquid, and (e) a transfer conduit for allowing effluent from the drain port of the first container to gravitate into the second container.
