Developing and Testing Strategies for Improving Cleanliness of Shared Sanitation in Low-Income Settlements of Kisumu,...

Sharing of sanitation is common in low-income settlements in Sub-Saharan Africa. However, shared (limited) sanitation facilities have been thought to pose health risks due to poor hygiene levels. Interventions to improve user behavior and cleanliness of shared sanitation are few, both in literature and in practice. This study details the codesign and testing of strategies to improve the cleanliness of shared sanitation facilities in low-income areas of Kisumu City in Kenya. The strategies included a cleaning plan, monitoring system, and discussions among users, and were codesigned through workshops with stakeholders and group discussions with landlords and tenants. These strategies were tested in 38 compound houses through the Trials of Improved Practices approach over a 5-month period. Field staff visited the compounds, observed the cleanliness of the shared toilets, and through discussions, encouraged users to develop a formal cleaning system and a monitoring plan. The discussions built social capital and collective action and facilitated uptake of the cleaning plan with notable improvements in cleanliness of shared toilets. The results support the acceptability of shared sanitation in low-income settlements, the importance of codesigning and coproducing solutions with users, and the need to evaluate the effects of these strategies on cleanliness of shared sanitation.
