Pathways to sustainability: A fuzzy-set qualitative comparative analysis of rural water supply programs

Study finds 3 pathways that lead to sustained functionality of rural water supplies across diverse geographies: (1) piped networks with professionalized, service-oriented management and post-construction support; (2) self-supply delivering water services on premises; and (3) community-managed water points e.g., deep boreholes with handpumps.
