WASH systems thinking has, over the years, been arguably more focused on water supply than sanitation and hygiene. Will Tillett (Aguaconsult) has collaborated with Robert Gensch (German Toilet Organisation) in the development of a discussion paper seeking to adapt systems concepts and conceptual frameworks to better represent these WASH sub-sectors. The paper proposes an adapted conceptual framework for WASH systems, and suggests checklists that could be used to analyse the status of the WASH system. It also includes examples of systems strengthening for sanitation and hygiene across the nine proposed ‘building blocks’ of the WASH system. The paper was undertaken as part of the Sustainable Services Initiative, with support from Viva con Agua and Welthungerhilfe. You can download the Summary here or the full report below.
