The basic fundamental of its utilisation for the mentioned purposes consists in a sufficient quantity and a good quality of groundwater. The elementary school in Kalna nad Hronom village is a very good example from the above mentioned point of view. It is possible to obtain there a significant amount of qualite groundwater with a required temperature, which is bound on gravel alluvia of the Hron River.
