SWS is working with a number of in-country partners to assess promising maintenance models, capture information about their performance, and, critically, analyze the systems that underpin these models, recognizing these "sub-systems" as part of a wider WASH system, nested in a broader political economy both at local and national levels. Our work focuses on preventive maintenance models, which are those that proactively service, repair, and replace hardware to deliver a more reliable, guaranteed service.
