UNHCR WASH manual – Practical guidance for refugee settings

The UNHCR WASH Manual (8th Edition, February 2026) is the result of an open and collaborative process with WASH actors who have active programmes supporting refugees. It has been written primarily for use by UNHCR staff, WASH actors, national governmental authorities, emergency response coordinating bodies, contingency planners, and programme evaluators, and is a useful reference for any individuals or organisations involved in providing WASH services in refugee settings.
