Necessary conditions for sustainable water and sanitation systems

What is it about?

Water and sanitation services confer significant health and economic benefits, but only if these services can be delivered on a consistent basis. We examine how much previously implemented interventions have succeeded in delivering sustainable services and identify transferable lessons.

Why is it important?

Most efforts to improve the sustainability of water and sanitation service delivery in schools have failed. Existing interventions tend to focus on resource provision only. We find that sustainable service delivery depends on three simultaneously necessary components: resources, information, and accountability. Key knowledge gaps remain regarding the types of investment that support locally effective information and accountability mechanisms, and the conditions under which their integration with resource provision leads to truly sustainable service delivery.
