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.
