Drinking water and water for domestic use often come from groundwater. In order to protect this water, local water authorities can apply to local administrative authorities to mark certain locations as water protection areas. The size of these areas is calculated in such a way that the quantity of groundwater taken from them corresponds to the actual rainfall going into them_ In the water protection areas certain uses of the land and activities on the land are banned or restricted.
