Developing countries struggle to provide adequate water, sanitation and hygiene (WASH) services to their citizens, in particular in rural communities, due to insufficient technical capacity, aging or failing infrastructure, and a lack of funds for daily operations.  The Circuit Rider Program, hosted by the Desert Research Institute, is a model proven to increase the long-term sustainability of these small, rural water systems.  A small group of qualified WASH technicians rotate through a circuit of communities providing advice and training to local operators on issues of sustainability, governance, treatment technologies, operations, and maintenance.  Over time, the Circuit Riders increase the capacity of communities they serve to assume effective responsibility for their WASH systems.
