The basis of the Urine Diversion Toilet is the diversion and separate processing of urine and faeces. The urine is led into a soak pit, or alternatively collected in a suitable container and re-used as agricultural fertiliser.
The faeces are collected in a pit where they dehydrate (all the water is removed from the faeces). When faeces are dehydrated, the volume generated per person is equivalent to no more than a bucketful per year. Dehydrated faeces are odourless, and most of the bacteria and viruses are destroyed over time.
After composting, it can be used as a soil conditioner or alternatively disposed of by incineration.
Advantages: Hygienically acceptable
No water required
Faeces are easily collected and removed, resulting in very low operating cost
No expensive treatment of sewage required
Composted faeces are excellent soil conditioners
Diverted urine is a very good plant fertiliser
Less environmental pollution
