In collaboration with the Water and Sanitation Program of the World Bank, Aquaya developed and conducted a randomized controlled trial in rural Kenya aimed to compare different marketing strategies for plastic latrine slabs and assess their health benefits.
This study supported the Water and Sanitation Program’s ‘Selling Sanitation’ initiative and its goal of developing and promoting market based sanitation solutions that are appropriate for rural settings of East Africa.
Aquaya conducted baseline surveys to collect data from approximately 4, 000 households (in two rural counties: Busia and Nyeri) on demographics, hygiene habits, socioeconomic status and sanitation infrastructure. We collected and analyzed key sanitation-related health data among children under three years of age such as diarrhea, worm infections, and weight. Follow-up data was collected in 2017 to monitor the progress of the sanitation marketing and evaluate the potential strategies for expanding access to safe sanitation. In addition, willingness-to-pay of the latrine slabs was conducted during the follow-up.
