The approach taken typically includes the decentralisation and commercialisation of water supply and sanitation (WSS) services, taking into account the needs of the poor in particular. This report gives an introduction to the water kiosk concept, its impact and challenges, and an example of a best practice implementation: the case of Zambia.
