An excreta flow diagram (also often described as a shit flow diagram or SFD) is a tool to readily understand and visually communicate how excreta flows through a city or town. Based on the contributing population it shows how excreta is or is not contained as it moves from defecation to treatment then disposal or end-use, and whether the flows are safe or unsafely contained.
This video shows how the SDF was introduced in Indonesia and why the Indonesian government sees it as a useful tool to improve urban sanitation.
