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.

From 2014 – 2018 the SFD Promotion Initiative has been managed by GIZ under the umbrella of the Sustainable Sanitation Alliance (SuSanA), supported by the Bill & Melinda Gates Foundation through two grants (2014-2015 and 2016-2018). Phase III of the SFD Promotion Initiative is being managed by the University of Leeds and the Center for Science and Environment, supported by the Bill & Melinda Gates Foundation through two additional grants. The secretariat of the SFD Webportal and Helpdesk are remaining with GIZ as part of the SuSanA secretariat.

Mirchaiya Municipality is situated in Siraha District of Madhesh Province in the southern region of Nepal. It is divided into twelve wards and covers an area of 91.97 sq. km. It was established on May 18, 2014 by merging the already-existing Village Development Committees (VDCs), Rampur Birta, Malhaniyakhori, Radhopur, Ramnagar, Mirchaiya, Phulbariya, Sitapur Pra. Da., and Madheshpur Gamharia. It lies at 26.4955° N latitude, 86.1516 °E longitude and at an altitude of 129 m above sea level. The municipality has a total population of 59,425 and is residing in 12,250 households.
Siraha District was declared Open Defecation Free (ODF) on March 23, 2018. Still, 9% of households do not have toilets whereas 91% households have the coverage of improved sanitation facility. The households without improved sanitation facility opt for open defecation. About 4% of households with improved sanitation facilities rely on offsite sanitation systems and 87% rely on onsite sanitation systems. Households with onsite sanitation systems have different sanitation technologies. About 2% of households have septic tanks, 47% have fully lined tanks, 22% have lined tanks with impermeable walls and open bottom, 14% lined pits with semi-permeable walls and open bottom, and 2% have an unlined pit.
The SFD graphic shows that excreta generated from 30% of the population are safely managed while excreta generated by 70% of the population are unsafely managed. The proportion of safely managed FS generated from 30% of population is temporary, since the FS has not been emptied. Once the containment starts to fill, the proportion of not emptied FS will be unsafely managed under the current practice of Faecal Sludge Management (FSM).
