SFDs are a new way of visualizing excreta management in cities and towns

Improving understanding of urban sanitation

Background

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.

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.

Make your own SFD

You can reach out to us any time, we are ready to support you throughout the process.

As sanitation practitioners and city officials recognize how effective SFDs are in engaging and stimulating dialogue on excreta management to achieve better sanitation, the number of SFDs being prepared all over the world will increase rapidly.
