While sanitation is no longer “forgotten,” there is much to be done—and learned. For example, how can governments design and carry out sustainable large-scale rural sanitation programs? What are the most effective programmatic approaches and what are at-scale service delivery models? What is the evidence of what works? And what factors influence the long-term sustainability of rural sanitation program interventions?
Water and Sanitation Program (WSP) has been working with partners and governments to address these questions and learn how to design and operationalise sustainable rural sanitation at scale. It is a work in progress: much has been learned, and more learning is needed. This Working Paper synthesises this work and shares lessons learned.
