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.

Cities have their own filter system, which very remote villages do not have. What kind of water do people drink in such villages?

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.
