Water supply systems in the past greatly influenced on the development of the society in various lands. However, today the water supply system represents an irreplaceable way of drinking water supply. This thesis presents the operation of the water system in Murska Sobota. It describes the facilities and equipment that ensure uninterrupted supply with drinking water in the municipalities of: Murska Sobbota, Moravske Toplice, Puconci and Cankova.Because this part of Pomurje is dominated by intensive farming, there are some problems with the supply of drinking water regarding to the presence of nitrates and pesticides. I gathered data from the archive and displayed them in transparent tables to determine the actual state of pollution of groundwater pumping stations and water supply
system. The data shows that the water in the system is clean. Some problems are occurring in the water supply station Črnska meja for which I have made several proposals for reduction of pollution. Before entering the water system the water mixes from all of water supply stations, thus ensuring adequate quality and quantity of drinking water in the system. Current state of the system is the result of good work in the past. Due to that it is necessary to continue to strive that in the future there will also be no difficulties in providing sufficient quantities of safe drinking water.
