An SFD for any city or town is in three parts:

  1. a diagram which shows the pathways all excreta generated by a city's population takes from defecation to final fate - either unsafe discharge to the environment, or safe reuse/disposal;
  2. a concise narrative report on the diagram and the service delivery context - including the enabling environment within which the services are being delivered; and
  3. a complete record of all the data sources used in developing the diagram and report - the stakeholders consulted, documents reviewed and all validation and quality control exercises implemented.
