Frontend: The front end presents a pedestal with urine diversion for male and female users, where the first liquid separation occurs. The pedestal incorporates a child safety seat and a stepping block for small children. The toilet has a handwashing facility inhouse for health and hygiene purposes.
Treatment & reuse/disposal: Urine and faeces are separated in the toilet bowl. The Urine is removed from the system via an ecological pipe connected to the base of a vegetable garden behind the toilet. Faeces, on the other hand, are contained in a sealed container (in the substructure) right below the toilet superstructure. In this container, the second liquid separation occurs by aeration as cool air enters the pedestal via an air inlet between the pedestal lid and the seat and hot air moves from the sealed container upwards via a vent pipe thus drying the faeces faster. The faeces are raked to the back of the container to dry even faster resulting in a reduced content volume which can be removed annually and used as fertilizer. The system requires minimal emptying since the excreta is treated in situ and is only emptied to remove the by-products for reuse application.
Structure: The substructure is constructed using bricks while the superstructure uses precast slabs.
Ideal context: While it is largely a dry system, developers recommend occasional (and regulated) use of water to enhance hygiene. The technology, therefore, presents a sanitation system for both waterborne and dry (ventilated improved pit) structures.
