Handwashing With a Water-Efficient Tap and Low-Cost Foaming Soap: The Povu Poa "Cool Foam" System in Kenya

Jaynie Whinnery et al. Glob Health Sci Pract. .

Abstract

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.

Water- and Soap-Dispensing Elements of the Povu Poa Handwashing System (A) Users can operate the Povu Poa Swing Tap hygienically with the back of their hand. The swing tap dispenses water from up to 3 holes; users can control the amount and flow of water coming from these holes based on how far forward or backward they pull/push the tap. (B) The Povu Poa Soap Foamer creates foam by mixing soapy water and air.
