Abstract: An apparatus, system, and method are provided for facilitating the cleaning of residual concrete from the dispensing elements of a truck, such as from the hopper, main chute, and auxiliary chute of a concrete mixing truck. The apparatus of the invention includes a catch basin that is mounted on and carried by the truck for receiving the runoff resulting from washing the concrete residue from the dispensing elements of the truck. A funnel assembly is mounted on the dispensing chute, and a hose is connected between the funnel assembly and the catch basin. The dispensing elements of the truck are then washed using water or other suitable liquid, and the mixture of liquid and residue passes through the funnel and hose, and into the catch basin. The system may also include a means for supporting and cleaning an auxiliary chute. The runoff received by the catch basin may be emptied at a later time and properly disposed of or recycled.
