ABSTRACT:
A recirculating sewerage system comprising a water closet, a selectively inclined effluent receiving member including filtering media at least at the upper portion thereof, means for directing the effluent flushed from the water closet onto the top surface of the effluent receiving member proximate the uppermost portion thereof whereby the liquid portion of the flushed effluent will pass through the filtering media and the solid portion of the flushed effluent will slide down the effluent receiving member, means for collecting the portion of the flushed effluent which passes through the filtering media, means for selectively recirculating the filtrate collected in the collecting means to flush the water closet, means for selectively draining the filtrate collecting means, means for collecting the portion of the flushed effluent which slides off of the effluent receiving member, a reservoir for receiving grey water discharge from a bathing facility, means for selectively directing grey water contained in the reservoir to the filtrate collecting means, and means for directing grey water from the reservoir to the bottom portion of the effluent receiving member when the level of the grey water in the reservoir exceeds a predetermined maximum level whereby any solids which remain on the effluent receiving member will be washed therefrom into the solids collecting means.
