Rapid Assessment of CRS Experience with Arborloos in East Africa

This rapid assessment reviews sanitation activities by Catholic Relief Services in East Africa, in particular the promotion of the Arborloo—an innovative latrine designed to help achieve sustainable and scalable sanitation improvements in rural Ethiopia, South Sudan, Kenya and Uganda.
