A self-cleaning flooring system for catching waste products has at least one module comprising a drain pan and a floor grid. The drain pan has a ramp and a central drain outlet. The ramp extends around the drain pan defining a drain pan periphery. The ramp slopes downward from the drain pan periphery towards the drain outlet. The drain pan periphery has a plurality of discharge ports spaced therealong for discharge of flushing fluid onto the ramp such that the waste products are washed down the ramp towards the drain outlet. The floor grid extends across the drain pan and is mounted upon the drain pan periphery for supporting personnel standing thereon while permitting waste products to pass therethrough. The module is interconnectable to horizontally adjacent modules to form the flooring system.
