The new handwashing system, designed with end user input, features an economical foaming soap dispenser and a hygienic, water-efficient tap for use in household and institutional settings that lack reliable access to piped water. Cost of the soap and water needed for use is less than US$0.10 per 100 handwash uses, compared with US$0.20–$0.44 for conventional handwashing stations used in Kenya.

Using an interactive and iterative design approach involving representative end users, we created a new handwashing system in Kisumu, Kenya, to make handwashing convenient and economical in areas without reliable piped water. The innovative and adaptable system, branded as Povu Poa (“Cool Foam” in Kiswahili), integrates a cost-effective foaming soap dispenser with a hygienic, water-frugal water tap in a secure and affordable design.
