A portable toilet appropriate for disaster response is presented in this report. The urine is diverted and the feces undergo a lactofermentation process. Biochar is added also to the feces to eliminate odor and facilitate the reuse of the excreta as a soil additive. The design, costs, logistics and expected challenges are discussed.

Since the area is characterised by high groundwater tables, so called “ventilated double vault urine diversion dehydration toilets” (UDDTs) were implemented to not contaminate the groundwater, and thus not threaten public health (unlike pit latrines).

The three main challenges were finding an adequate place on the compound for the UDDTs, the use of UDDTs e.g. daily practices and maintenance, and the reuse of dried excreta.

Groupe URD looks at the case of Eastern Chad, an example of a major long-term crisis. From an acute emergency in 2003, the crisis has gone through a number of phases. The appropriateness of aid mechanisms is currently being questioned, with a particular focus on sanitation. Sustainable sanitation can help to improve the quality of life of refugees and IDPs as well as local populations. From this perspective, what lessons from Eastern Chad could be useful in other contexts?

The indiscriminate and erratic handling and disposal of waste within health-care facilities is now widely recognized as a source of avoidable infection, and is synonymous with public perception of poor standards of health care. Water pollution and inadequate wastewater treatment pose important risks to health.
