Yes, increasingly UDDTs are being proven in emergencies however they are still not well known or commonly used in the humanitarian world. Many UDDTs don’t work for multiple reasons, so should be only implemented after an assessment with the users to see if they are open to such an intervention.
Urine and faeces are diverted using a urine diversion toilet bowl or squatting pan and are collected separately. While the urine goes into a container or jerrican (or is drained away in a soak pit if there is no re-use intention), the faeces are collected in vaults underneath the toilet seat or squatting pan, where they are stored and dried. The alternating vaults allow for prolonged storage and treatment takes place of the collected faeces in the unused vault. Separating urine also accelerates the drying process of faecal matter and reduces odor and flies. The urine, which contains the most nutrients of human excreta, can either be drained into a soak pit or collected and reused (SusAna WG8 Factsheet).
