German Organization for International Collaboration (GIZ) Shit Flow Diagram Platform


Shit Flow, I beg your pardon? No, there is no typing error here. The German Society for International Cooperation (GIZ) is actually involved in the creation of so-called Shit Flow Diagrams (SFD). These can be used to study how excrement flows through a city and how this process can be optimized. After all, clean water and adequate sanitation are essential for healthy ecosystems and secure livelihoods.

By creating the SFD website, we helped GIZ bring a simple tool for improving sanitary conditions to the world.


The website educates about the importance of regulated sanitation and quickly directs interested parties to the SFD Generator. When programming the site, we opted for a CMS-based concept, so that our client can adapt the content himself at any time. This way, the information about the SFD project is always up-to-date and the processes are kept short.
