Water supply of the City Salgótarján 483 Summary. The water supply of the city of Salgótarján can be secured on base of the above mentioned possibilities of water sources at the following manner. 1. Water works to be established at Kis Gedőc Puszta would present an ideal solution of the problem. The water basin is here larger than 10 sq. km. The necessary amount of water can be stored by a valley dam. The water of the water holding layers of glauconitic sand-sandstone can be made accessible by deep borings and can be obtained by pumping. The water of the Holocenic sediment gravel bed in the inundation area can be reached by wells of low depth. This water works would have the advantage of being able to be enlarged at any time in the future. 2. The water works to be established in the valley of the rivulet at Salgó (with a water basin of 5.35 sq. km) could have the necessary water yield in case of securing all the possible water sources. The water works should use: a) the water of the well Pólyán and other springs. b) the water of the gravel in the inundation area and of the gravel bed by the location of borings of low depths, c) the water of deep borings located in the glauconitic sand-sandstone, d) the storable precipitate water by means of an eventual valley dam. This kind of water works has the drawbacks caused by an absence of any future development possibilites. A partial solution of the problem would consist of an aquaeduct leading the water of the named springs into the city. Public wells could cheaply provide the city with potable water in this manner. 3. The water works to be established at the Market Place or its environment could utilisate the water of the gravel bed and the glauconitic sandstone by deep borings. Its advantage would consist of its position (in the centre of the city), its drawback would be the absence of future development possibilities and the higher costs of water production owing to the continual pumping out of deep layers. Primarily the financial position of the city must be kept in mind when choosing one or another of the mentioned alternatives for securing its water supply. It must be emphasized that in each case a previous detailed study must be made to determine the quality and quantity of the water available.
