Water supply of the City of Salgótarján.

1 By: Dr. Sándor Vitális. The water supplied to the city of Salgótarján originates today mostly of 500 wells of 3—28 meters depth, yielding in greater part ordinary soil water. Most part of these wells utilisates the water of the Holocenic inundation sediments of the rivulet Tarján. Some wells, however, take their water of the lower Miocenic gravel bed and the upper Oligocenic glauconitic sandstone. The water of the most wells is inficiated and defiled, inavailable for potable purposes. The frequency of typhoid fever epidemies urges the final solution of the water supply of the city. Demand of water. 15.000 inhabitants of the city want good and healthy potable water. Calculating with a daily water consumption of 100 liter per head the water demand of the city of Salgótarján amounts annually to 547.000 cu. m. (= daily 1500 cu. m. or 1041 liter per minute or 17.36 liter in each second). The sources of water must therefore be chosen SO' as to be able to supply in each minute at least one cu. m. water. With regards to future developments of the city, it is advisable that this water amount possibly should be doubled without disturbancies. Possibilities of water supply. The hydrogeological knowledge of the environment of the city gives following possibilities for water sources: I. External (surface) waters. 1. Precipitation water. Precipitation water could be stored by the building of a valley dam between Salgótarján and Somoskőújfalu northly of the city in the valley 1 Text of an address held at the session of the Hydrological Section of the Hungarian Geological Society at April 27, 1938.
