Innovation Description

To use mobile banking and SMS to improve access to promote purchase of water filtering methods in rural communities.
How does your innovation work?
Kisumu has widespread mobile banking, unsafe local water, and many households who aspire to own the ceramic Chujio filter. The Chujio filter is one of the most ubiquitous water filters in developing countries and can be manufactured locally almost anywhere in the world. Safe Water and AIDS Program (SWAP) has a supplier in Western Kenya (the Kenya Ceramic Project) with whom they already contract. Because this sales model does not necessitate any change in market structure, distribution channels or policy, it is potentially very cost effective.

Planned Goals and Milestones

A very small initial pilot in peri-urban Kisumu, Kenya showed promising results: 10 of 16 households offered the Chujio filter under this sales contract accepted the offer, and 8 of those 10 successfully made their first payment on time over M-PESA. These households at present are current on their payments. RAND Corporation will perform a larger pilot study of this sales contract to distribute the Chujio filter in Kisumu, a medium-sized city in western Kenya.
