New SFD Reports
There are nine new SFDs (Chingola, Choma, Kabwe, Kafue, Kitwe, Mansa, Mahakali Municipality, Banepa Municipality, Jayaprithvi Municipality) accessible through our database now.
Check out the new drawings on the SFD graphic generator - when selecting sanitation systems, you can now see what each of the systems look like and double check that it matches the situation in your city.
A BIG thank you to the artist James McKay of the University of Leeds for producing the drawings – we think they are great!

SFD Manual
The SFD Manual was translated to Arabic and can be downloaded from the SuSanA Library!
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.
Discover the SFD reports, training events and presentations across the world.
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.
Do you want to prepare an SFD? Check out the tutorial videos, FAQs and the SFD Manual.
The SFD Manual describes the process followed within the SFD Promotion Initiative for the production of SFD graphics and reports. It includes guidance on data collection and analysis on how to use the SFD Graphic Generator and the definitions of terms and variables.
