Organisations around the globe are invited to use the methodology for creating a WFD and make water management practices visible in their city!

The basic method consists of five steps:

These five steps are described in more detail in a user guide that can be downloaded here: quick guide

To collect the data and bring it into the correct format, you can use the Excel template: data template

The actual making of the diagram is done using Sankeymatic.

After you computed the diagram in Sankeymatic, you can use the PowerPoint template to finalise the diagram: powerpoint template

The most complex step is the data collection. Depending on the data available, it can take several months to complete the data collection. However, there a draft version of the diagram with estimations instead of data can make data easier available or provoke a more detailed data collection. Once the data has been collected and is in the right format, making a diagram out of it is simple and only takes a couple of minutes.

In collaboration with the wastewater utility of Zurich (ERZ) an extended method was developed that also takes into consideration the total rainfall within the system boundaries. Currently, there is no user manual available for this method. The method is described in a final project report  for the ERZ (in german).
