a toilet facility that is completely independent of water supply and sewer lines includes a house having a waste - receiving tank within it and another tank located outside the house . the two tanks are connected by a transfer pipe provided with a pump for pumping the waste from the inside tank to the outside tank . the outside tank is provided with a discharge pipe leading from it , and this pipe likewise has a pump for removing waste from the outside tank . the discharge pipe for the outside tank easily connects with a collection receptacle that can be detached and disposed of . each tank contains an aeration pipe to which an air compressor is connected , thus enabling pressurized air to bubble through the waste in the two tanks and to activate aerobic bacteria in the waste . each tank also contains a heating element which normally maintains the waste in the tank at about 97 ° f ., but has the capability of elevating the waste to a temperature above the boiling point of water so that the water may be evaporated from the waste . the pump in the discharge line may not be energized within 48 to 96 hours of the last operation of the pump in the transfer line so as to provide sufficient time to purify the waste in the outside tank after the last addition to that tank . the house has a translucent dome - shaped roof provided with a gutter at its lower edge and a vent that raises and lowers at its top . major components of the house are formed from plastic using rotational molding techniques .
