Context is key in sustainable WASH programming. Social norms, engineering requirements suited to the local and physical environment and the types of governance structures in place to support communities vary markedly and are specific to countries and their sub-regions. Although what marks large scale WASH programming in one place may not apply elsewhere, drawing lessons from these experiences remains valuable, if properly documented.
Plan International USA reviewed the programming experience within the Cambodia Rural Sanitation and Hygiene Improvement Program and developed this synthesis of insights, based on an array of program and performance-related reports released during the first three years of the program. This review is designed to assist local advocacy efforts to bring community-led total sanitation (CLTS) to scale and share emerging themes and lessons learned to date from programming experience of relevance to other implementers in the WASH sector.
