In one aspect, a waste disposal for processing waste may generally include a housing and a motor disposed within the housing. The housing may define an inner sidewall surface extending around an inner perimeter of the housing and a discharge outlet. The motor may include a stator and a rotor at least partially surrounding the stator. The rotor may include a sidewall defining an outer surface. The motor may be disposed within the housing such that an annular gap is defined between the inner sidewall surface of the housing and the outer surface of the sidewall. When the rotor is rotated relative to the stator, water may be drawn through the annular gap towards the discharge outlet.
