The quality and quantity of water throughout history have been an important factor in determining human well-being. Many types of pollution threaten rivers, including aquatic organisms, pesticides, soil erosion, chemical fertilisers and industrial pollutants. An extraordinary asset for our country is the natural waters where their quality is particularly important from a chemical point of view. From the studies carried out so far on the quality of natural waters, there are shortcomings mainly related to the limited number of physical-chemical parameters measured as well as to the water resources being processed. As for consumption, the quality of water is of great importance, and the purpose of this work is the analysis of water quality in the Aqueduct, which is of great importance for all residents who are supplied by this Aqueduct. The basic substance of life is water, therefore it is necessary to determine the quality of drinking water in the water supply network through physical-chemical and organoleptic parameters. The analysis of water in the water supply network was done before and after processing every four hours during the day and three days in a row. The obtained results show the condition and quality of raw water and processed water used by consumers, whereas a reference basis they are taken from Directive 98/83/EC for the quality of water for human consumption. From the results, we came to the conclusion that the water analyzed after processing is of sufficient quality to be used as drinking water.
