Abstract: Possibility of the use of solar radiation for reduction of Natural Organic Matter (NOM) content in natural lake water, as a source for drinking water preparation, was the topic of this research. Solar radiation alone does not have enough energy for sufficient degradation of NOM, but in combination with heterogeneous photocatalyst-titanium dioxide (TiO2), with or without other chemicals, the degradation potential could increase. In specific geographical conditions in Republic of Croatia, e.g. Adriatic islands or Dalmatia, solar radiation could be used for photocatalytic degradation of natural organic matter (NOM) in surface waters and therewith lighten the process of preparing them to the potable water. Specific quality of the geographical locality appears in fact that it is a very attractive tourist destination, especially in period June–September. In this period the drinking water demand is the biggest and, fortunately, the intensity of the solar radiation, too. So, there is a proportion between the drinking water demand and solar radiation available for the use in drinking water treatment.
