The transition from purchasing liquid chlorine to sodium hypochlorite production has been considered. The advantages and disadvantages of different disinfectants that can be used in the disinfection stage of drinking water have been demonstrated. The focused attention on the drawbacks of using liquid chlorine includes risks during dosing, transportation, storage, and the formation of chlorinated organic compounds, predominantly trichloromethanes, particularly chloroform, which exhibit significant mutagenic effects and a carcinogenic risk. The materials of the Smolinsky water supply and sewerage system of the regional communal water supply and sewerage enterprise "Dnipro-Kirovohrad" regarding the technology of disinfecting natural water and the quality of drinking water have been analyzed. The expediency of using a purchased sodium hypochlorite solution in the disinfection stage of drinking water has been determined. It has been shown through examples that some problems associated with the use of purchased sodium hypochlorite solution can be solved by launching its own production. Changes to the current technological scheme have been proposed with the aim of reducing chlorine by-products and improving the organoleptic properties of drinking water.
