Abstract: A method, a system and an apparatus for removing cement residue located within a concrete discharge chute and controlling the collection of debris and wash water, in a concrete mixing truck. The concrete discharge chute comprises a main chute and an end chute connected to the main chute via a hinged connection. In addition, a barrier plate having a rubber seal is connected to the end chute. When concrete discharge is completed, the barrier plate automatically prevents the discharge of debris by closing off the discharge chute when the end chute is raised into an upright and secured position. The barrier plate also has an optimally placed opening to control material flow along the main chute. The opening is fitted with a valve which may be connected to a drain hose to collect wash water into a collection tank securely positioned on the concrete truck.
