Abstract: An effluent recycling sanitation system. A first container forms a placid waste separator connected in series to a second container forming an effluent recycling chamber. Both containers are located below ground and are formed from reinforced concrete having a fiberglass liner separated by insulation preventing outward flow of heat energy. The first container is sealed relative to the atmosphere providing for biodegradation of incoming sewage with a vertically extending screen allowing only liquid sewage to flow outwardly into the second container. An air inlet tube extends into the second container allowing fresh air to move into the container with gases then being withdrawn via a second tube extending out of the second container and powered by an air turbine. A solar converter plus auxiliary heat coils located within the second container rinse the temperature within the second container. Liquid within the second container is evaporated via the outlet tube.

Abstract: A waterless sanitation system with ventilation. A toilet within a building is located over a pit having a solids holding basket suspendedly mounted within a liquids holding tank. A plurality of air inlet pipes extend externally of the building downwardly through the basket and into the liquids holding tank with a plurality of apertures provided on the pipes allowing the air to enter both the basket and tank. An exit pipe extends upwardly from the tank through the basket and through the roof of the building. A plurality of apertures in the exit pipe allow the gas within the tank and basket to escape. An exhaust fan is provided to pull the air downwardly through the inlet pipes and the gas outwardly through the exhaust pipe. The inlet pipes have mouths oriented to catch the wind assisting the flow of air.
