Sustainable WASH Systems Learning Partnership Fact Sheet

Sustainable services remain a daunting challenge in the water, sanitation, and hygiene (WASH) sector. Traditionally, national and local governments, WASH service providers, and development partners have focused on the construction of WASH facilities and the expansion of service coverage. Less emphasis has been placed on sustaining and maintaining existing WASH services. As a result, failure rates of water supply and sanitation systems continue to be high.

Universal access cannot be achieved without addressing the sustainability of WASH services. This requires taking a comprehensive, long-term view of service delivery and changing local systems. While the sector recognizes this shift in programming is necessary, there has been limited exploration of what approaches work, what benefit they bring to sustainability, and how they can be applied effectively.
