An SFD presents a clear picture of how wastewater and faecal sludge management services are delivered in a city and the resulting challenges; these can then be linked to aspects of service delivery where improvements are needed. Primarily it provides technical and non-technical stakeholders with an easy-understood advocacy tool that can be used to support decision-making on urban sanitation planning and programming.

Importantly, an SFD does not provide a 'shortcut' around integrated sanitation planning, promotion, investment, design, construction, operation and maintenance; these remain as very necessary components for implementing successfull urban sanitation.
