The most important action was building a second water-supplier called the “900 metres Conveyance”; whose construction was ended in 1961. In the meantime, in order to cope with water emergency situations an auxiliary aqueduct was also built; it consisted in a system for purifying the superficial water of the river Brentella, which partially overcame the shortage of water complained by the citizens. Afterwards relevant actions were taken in order to improve the efficiency and the functionality of the whole water system in Padua. Among the many actions taken, we can mention the following most important ones:  Padua aqueduct contributed to solve the problems related to water supply of some smaller distribution authorities. The following are the most significant data concerning the aqueduct management:   The water arrives to the receiving system after undergoing a long natural conditioning process in the deeper layers. The most varied rock fragments melt and shed their salts into the water, mineralising it. Therefore, Padua waters are classified as “medium-mineral” waters. The AMAG company has been dealing with the disinfection treatment of the waters introduced into the pipes since its start. Despite concerns in the 21st century about water quality; however the water is tested and drinkable according to legal standards, so much so that the administration is currently planning to build some cleaning up systems to keep the water within optimum quality standards.
