Evaluation of User Experiences for the Clean Team Ghana Container-Based Sanitation Service in Kumasi, Ghana

There is a lack of affordable and acceptable sanitation solutions for dense, low-income urban settlements. One option that has been proposed is container-based sanitation, where a sealed cartridge installed in a free-standing toilet is regularly changed and adequately separates users from their excreta. Though container-based toilets are considered a safely managed sanitation solution that meets the Sustainable Development Goal for sanitation, little is known about user experiences to inform how such a solution should be viewed by governments. We conducted a longitudinal prospective cohort study of changes in objective and subjective measures of sanitation quality due to the Clean Team Ghana (CTG) container- based toilet service in Kumasi, Ghana from June to December 2019. We collected data immediately prior to installation of a toilet and 10 weeks afterwards for 292 customers. Most initially used public toilets with good structural quality, but sometimes had poor cleanliness, a lack of handwashing facilities, and required a 14.3 minute mean round trip time to use. The evaluation found that CTG delivers a high-quality service that positively impacts the quality of life of CTG customers, as well as saving them money, reducing gender gaps in quality of life, and addressing the needs of those with physical disabilities. Satisfaction with CTG toilet and service characteristics was high, with the largest increases for satisfaction with smell, comfort, disgust, and privacy. Women in particular were positively impacted both for explicitly gendered indicators like the ability to practice menstrual hygiene management, and other indicators where women scored lower than men at baseline, including ease of access, ease of use, and cleanliness. Use of the service also benefitted those who had been unable to use a toilet for physical or social reasons beforehand. Problems with the CTG service, such as leaking, filling, smelling, or not being replaced as scheduled, were reported by fewer than 10% of customers. While one product or service does not fit the needs of all customers, this evaluation supports the growing body of evidence that container-based sanitation provides a service valued by users and acceptable to policymakers in dense urban settlements.
