2. Why is a report needed?

The SFD Graphic indicates where the problems lie in an urban area, but without understanding the local context you cannot understand why these situations occur.  The SFD Report will help to answer questions such as “Why is only half of the excreta produced onsite collected?” or “why is only half of the wastewater that reaches the treatment facilities treated?” The SFD Report provides information on the institutional frameworks, roles and responsibilities, regulatory aspects, and other issues that directly or indirectly impact the provision of sustainable sanitation services. It also includes the assumptions used to prepare the SFD Graphic.
