WASHPaLS conducted a comprehensive review of WASH grant-funding since 1980 to identify household sanitation supply projects using an MBS approach, assessed project characteristics and outcomes (population impacted), and reviewed project strategies against three key factors for scaling MBS (customer and business finance; availability and viability of local entrepreneurs; appropriate toilet product and business models).
This article discusses implications for improving the design and performance of MBS interventions globally and particularly in sub-Saharan Africa.
