The results o f the analysis o f the provision o f residents o f the city o f Tashkent with good-quality drinking water are presented. From water intake facilities, water is supplied to the distribution network after various methods o f water treatment, and it meets the requirements o f "Drinking water" GOST 950-2011 [1]. A variant o f retechnologization o f the water supply system by improving water quality with the help o f the considered water treatment technologies is proposed. The water quality o f the surface water supply source (the Bozsu River) has been assessed, and options fo r water treatment technologies from this water source have been proposed. Three variants o f reagent technological schemes have been proposedfor the treatment o f the Bozsu River water. These are the main methods o f drinking water purification - clarification, bleaching and disinfection o f drinking water.
