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.
