UNHCR Urine Diverting Dry Toilet (UDDT) Standard Operating Procedures

Double vault Urine Diversion Dry Toilets (UDDT) can be used as an alternative to pit latrines in refugee camps. They utilise two chambers for faeces, one of which is in use whilst the other is full and drying so that it can be safely disposed of after an appropriate period of time.
These Standard Operating Procedures (SOPs) were developed by Oxfam under UNHCR’s “Waste to Value” Project, which was funded by the Bill and Melinda Gates Foundation. They are largely based on UDDTs developed under the Waste to Value Project in Ethiopia.
