SFD Promotion Initiative

An excreta flow diagram (also often described as shit flow diagram, SFD) presents a clear picture of the outcome arising from wastewater and faecal sludge management practices and services in a city or town. This is expressed in terms of the percentage of the population. An accompanying report describes the service delivery context of the city or town.
The output from the SFD production process is a concise report (SFD Report) which contains the graphic (SFD Graphic), the qualitative assessment of the service delivery context and a complete record of the data sources used.
The SFD approach includes standardized guidance – a methodology and tools - for the easy production of standardized SFD Graphics. The SFD Manual – Volumes 1 and 2 (version 2.0), as well available in French and Arabic, and the SFD Graphic Generator were developed to enable the development of future SFD Reports.
The SFD Manual – Volume 1 and 2 (version 2.0) describes the process followed within the SFD Promotion Initiative (SFD PI) for the production of SFD Graphics and Reports and includes guidance on how to use the SFD Graphic Generator. Volume 1 of this manual is a guide for the data collection and analysis and should be read in conjunction with the accompanying Volume 2. The SFD Manual – Volume 2 includes:
• Part A - Master SFD Graphic
• Part B - Definitions of SFD Graphic Variables
• Part C - Definitions of Terms
• Part D - Sanitation Containment System: SFD Schematics
These documents were produced under the SFD Promotion Initiative and have been reviewed after being field-tested in more than 40 cities in Africa, Asia and Latin America. The results of this project are disseminated widely via the SFD portal hosted by the SuSanA (Sustainable Sanitation Alliance).
