Abstract

A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. Structure is provided for flushing the bowl and dumping the contents into the filter cassette and for subsequent refilling of the bowl. A filter is in the cassette for separating the particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Pumps and interconnected conduits are in the housing to transport fluid directly from an external source to fill the bowl after a flush, to transport and recirculate filtered fluid through the system for further waste disposal treatment, and to direct the effluent fluid from the system thereafter. Controls are provided to pass the fluid through the system and facilitate the collection and disposal of sewage waste within the system in a predetermined sequence.
