  • Patent number: 4163294
    Abstract: 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.degree. F.
