Abstract
A disposal unit, for the disposal of dog waste, comprises a casing having an inlet slot in its upper wall, from which a chute leads downwardly within the casing to a bowl. An outlet conduit, incorporating a U-bend water trap, leads from the bowl out of the casing for connection to a sewage system. A flushing cistern is mounted within the casing and is operated by an external lever. In use, the dog waste is picked up in a scoop, placed in a disposable paper bag, and then deposited through the slot. It slides down into the bowl from where it may be flushed away by operation of the lever.
