What is an SFD?

An excreta flow diagram (also often described as shit flow diagram, SFD) is a tool to readily understand and communicate how excreta physically flows through a city or town.

The fate of excreta produced by populations across the globe is often poorly understood. SFDs show how it is or is not managed as it moves from defecation to disposal or end-use. The SFD report presents the service delivery context of the city or town and the data sources used for the assessment.

SFDs Worldwide

Discover the SFD reports, training events and presentations across the world.

Over 120 SFD reports are currently available. 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 is increasing.

Make your own SFD

The SFD Promotion Initiative has developed a methodology and tools to enable the easy production of standardized SFDs by city stakeholders, development agencies and non-governmental organizations.

The SFD Graphic Generator is a quick and simple tool that allows the production of SFD graphics in three steps. Once you have the data for your city, you can easily generate the SFD graphic and download the results for reports and publications.
