The town of Szeged wanted to have very hot mineral water, and manual deep borings began in an old bored well (1927). According Ferenc Pávai Vajna’s report, the workers were able to reach a depth of 959 metres. At a depth of 944 metres hot water, the temperature of which was 52 degrees (with a ground temperature of 58 degrees) welled up. Its output was about 600 litres per minute, later it fell to about three fourth of the original volume. According to the chemical analysis (1936) the total weight of the salts solved in 1000 grammes of water was 1270 milligrammes. This meant that besides the mineral water of Borzhomi (in the Caucasus) and that of the Grand Grille (Vichy) this water belonged to the world’s three richest mineral waters. It is good as a purgative removing the pathological metabolic products from the body,or for flushing the body, it cures stomach and bowel complaints and disorders of the renal pelvis with good results, is useful for cystitis, for stopping urathic diathesis and preventing the formation of renal calculi. For the same reasons this kind of water was also used as boiler fluid to remove incrustation. Because of its iodine content it is useful for treating exophtalmic goitre. As soft water it is suitable for washing clothes or one’s hair, and cooled – or enriched with carbon dioxide – it tastes good and is liked even by those who cannot drink it hot. In 1937 Dezső Patzauer, who had taken out a lease on the spring, named the mineralwater after his young daughter Anna. He took out a permit, issued by the Ministry, and began to sell the Anna water as mineral and medicinal water, enriched with carbon dioxide (1938). In the same year he built a hall around the spring for those who wanted to drink the water, the hall was pulled down in the 1950s.
