The aim of the research was to study the state of the quality of drinking water, drinking water reservoirs over a long-term period to assess the necessary funding to optimize water supply to the population and protect water bodies in Uzbekistan in the face of climate change. The dynamics of the long-term state of water supply systems in a number of regions of the republic is characterized as unfavorable for the health of the population. Over the past ten years, the quality of drinking water has deteriorated by 1.2-10.6% in terms of chemical indicators, and for microbiological indicators - by 0.4-8.9%. Indicators of chemical pollution of water in reservoirs decreased by 11.9-19.8% in Khorezm, Surkhandarya, Andijan and Fergana regions. Water pollution levels increased by 11.9-18.6% in Karakalpakstan, Namangan and Kashkadarya regions. The hygienic state of drinking water supply sources in all regions of the republic is unfavorable due to the fact that the water quality in them does not meet the requirements of the republican standard for centralized drinking water supply sources. Studies have shown that for the base period the amount of financial costs for improving the conditions of drinking water use of the population and the protection of drinking water bodies will amount to 4 286.2 billion sums, and for the adaptation period - 7 665.1 billion sums.
