The fate of excreta produced by urban populations across the globe is often poorly understood. Particularly in low- and middle-income with rapidly expanding cities, excreta management represents a growing challenge; generating significant negative public health and environmental risks.
What is an SFD?
An excreta flow diagram (also often described as shit flow diagram, SFD) is a tool to readily understand and communicate visualizing how excreta physically flows through a city or town. It shows how excreta is or is not contained as it moves from defecation to disposal or end-use, and the fate of all excreta generated. An accompanying report describes the service delivery context of the city or town.
