SFD – Shit Flow Diagrams

SFDs are a new way of visualizing excreta management in cities and towns. The fate of excreta produced by urban populations across the globe is often poorly understood. Particularly in low- and middle-income countries with rapidly expanding cities, excreta management represents a growing challenge; generating significant negative public health and environmental risks.

As part of the SFD Promotion Initiative, Sandec is working on developing and standardizing a methodology for the production of SFDs, how to ensure credibility of data, and potential future uses for SFDs including monitoring of the Sustainable Development Goals (SDGs).

For more information and to download documents for the production of SFDs, please refer to the project website.
