This project is focused on water treatment in places where there isn’t an adequate or available public water supply. Around 20 % of Slovenes are not connected to the public supply, and even those who are often prefer to use water which they collect from other, natural, sources.

There is a common belief that spring water in Slovenia is clean, but since a large part of Slovenia lies on karst grounds, it is difficult to predict the flow of groundwater and the accompanying pollution.

The location chosen as a pilot area for the project lies in the Triglav National Park, where, contrary to public belief, spring waters are quite contaminated.
