Acceptability of urine diversion dry toilets in Dollo Ado refugee camp, Ethiopia.

Abstract Given the increasing frequency and duration of humanitarian emergencies worldwide, there is a need to identify a greater range of effective and contextually appropriate water, sanitation and hygiene (WASH) interventions. Typical sanitation systems may be poorly suited for some of the conditions in which humanitarian emergencies can occur, such as in drought-prone regions. Urine-diversion dry toilets (UDDTs) are one potential alternative sanitation option which can be used in these conditions. Between 2014 and 2016, the U.S. Centers for Disease Control and Prevention (CDC) partnered with local agencies to evaluate the acceptability of UDDTs in a refugee camp in Ethiopia. The overall goals were to provide evidence regarding the level of adoption and satisfaction with UDDTs in this emergency context and the factors associated with satisfaction. Two cross-sectional surveys were conducted 18-months apart, using a stratified design to sample UDDT and latrine users for comparison. The proportion who reported to use their UDDT consistently was 88.8% (95% CI 85.1–92.5) in the first survey and 93.4% (95% CI 90.6–96.2) in the second survey. Reported satisfaction levels were significantly higher among respondents in the second survey (p
