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.

Bardibas Municipality is located in Mahottari District, Madhesh Province of Nepal. It has total 14 wards and covers the area of 315.57 square kilometres. It is surrounded by Kamalamai Municipality of Sindhuli District in North, Aurahi and Bhangaha Municipalities in south, Dhanusha District in the east and Sarlahi District in the west.

The population density of the municipality is 236 people per square kilometre.
96% of the households in the municipality have a toilet. The 4% of the households without toilet defecate in nearby farms and forest. The municipality has a public toilet in a bus park area. The public toilet was constructed by Bardibas Small Town Water Supply and Sanitation User's Organization and is operated by individual service provider.
The SFD graphic shows that 65% of the excreta or faecal sludge generated are safely managed while 35 % are unsafely managed. The safely managed FS generated by 64% of the population is temporary as these FS is only contained. So once the containment gets filled and FS from the containment is emptied, the percentage of unsafely managed excreta would increase. The faecal sludge generated from 1% of the population is contained and safely treated in anaerobic biogas digesters.
