42. Achieving Sustainable Sanitation Chains Through Better Informed and More Systematic Improvements: Lessons from Multi-city Research in Sub-Saharan Africa

This paper presents the synthesized findings of the SPLASH Urban Sanitation research programme through the framework of the sanitation service chain. Urban sanitation service chains are complex and fragmented, involving a multiplicity of service providers and typically resulting in unsustainable or inadequate services. The aggregate data set covers a wide range of research methods including; household surveys, a randomized control trial, a willingness to pay survey prototype testing of technologies, focus group discussions and deliberative forums. Thorough the research, it has been possible to identify situations where incremental improvements are being made with varying degrees of success. Most importantly, it has identified weaknesses to the sanitation service chains where progress is either slow or extremely limited. It is through these weaknesses that key questions affecting the long-term sustainability of sanitation service chains need to be answered. (Link)
