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.
Bucket chlorination (where workers stationed at water sources manually add chlorine solution to recipients’ water containers during collection) is a common emergency response intervention with little evidence to support its effectiveness in preventing waterborne disease. We evaluated a bucket chlorination intervention implemented during a cholera outbreak by visiting 234 recipients’ homes across five intervention villages to conduct an unannounced survey and test stored household drinking water for free chlorine residual (FCR).
