Water on Earth is a vital element of living systems. Water is a medium that enables life and at the same time a medium in which a diverse eco systems exist. Natural waters contain dissolved gases, dissolved organic and inorganic substances and solid suspended materials. The quantities of dissolved and suspended substances are affected by: water temperatures, contact of water with the atmosphere, types of sediment the water is in contact, quantities of rainwater entering surface waters and quantities of waste substances, which are of anthropogenic origin. The results of water quality, according to the methodology of Eurowaternet - Lakes Aggregation of station data, were investigated and presented in a table form and by the location. The estimated value of water quality was obtained, expressed by the appropriate Water Quality Index. Water quality indicators are determined by the Serbian Water Quality Index method. The analyses are presented by the frequency distribution of the indicators SWQI, nitrate, total phosphorus, ammonium and BOD5. Related to that research, as a result of the applied methodology and the fact that modern water supply systems in the Republic of Serbia have predominantly relied on groundwater reserves, and lately more and more on water abstraction from reservoirs and their use after treatment, a proposal for the management of raw water quality was given.
