The article analyzes the topical issue of assessing the reliability of water supply in Kremenchuk, Poltava region, in the zoning of the water supply system. The scheme of the integrated water supply system of Kremenchuk was built to calculate reliability, which reflects the movement of water from the source to the consumers and the main structures of the water supply system. The work of the water supply system of Kremenchuk and its structure is analyzed. In terms of reliability, it is concluded that water pipes are the least reliable element. The statistics on the failures of the water supply systems of the city of Kremenchuk are analyzed. The calculations showed that the actual failure rate for steel pipes d = 1100 mm of water pipes in Kremenchug is 2 failures per 10 km of steel pipe per year, which is 2 times higher than foreign and domestic data. The reliability assessment of both the integrated and district water supply system of Kremenchuk was performed on the failure of water supply systems for both separately connected individual elements. Comparative analysis of reliability of the integrated and district water supply system of Kremenchuk without fail has shown that the zoning significantly increases the reliability of water supply in the Kryukivsky district, and the reliability of water supply of the Avtozavodsky district remains unchanged. In the integrated system in the Kryukiv district, the parameter of the flow of failures was 1/year, that is, about 3 times a year a break in water supply is possible. In the district system, both systems operate independently, which is why everything remains unchanged in the Avtozavodsky district, and the failure flow parameter for the Kryukivsky district is significantly reduced and is: 1/year, which corresponds to a water supply interruption of about once every 2.5 years. Thus, zoning can increase the reliability of water supply in the Kryukovsky district of Kremenchuk approximately 8 times.
