Abstract

The centralized water supply system from the water source to the consumer includes 3 main complexes: water intake, water treatment and supply and distribution. The reliability of water supply in the area depends on the reliability of each of these complexes, which, in turn, consist of a number of structures. The paper develops the developed principle of assessing the reliability of water treatment plants (WPP) by quantitative indicators of the quality of treated water. The assessment of the reliability of the current WPP was performed to reflect its work, which implements the "black box" model. That is, some process parameters have one value at the input and other values at the output. The disadvantage of this method is that it is impossible to assess the reliability if the process does not occur. In addition, it is impossible to assess the reliability of the BOC for another set of individual structures. And the advantage is the sufficient simplicity of calculating the reliability indicator. Data on the purification of the Dnieper water at the Kremenchug WPP in terms of turbidity and chromaticity are used. Graphs of average variable indicators of turbidity and chromaticity of Dnieper water at the entrance of the WPP and graphs of exceedances of maximum permissible concentrations of treated water are constructed. The main indicator of reliability for municipal water supply facilities is the coefficient of readiness of KD, and the basic indicators of reliability are the average operating time for failure T and the average recovery time of the TR. The possibility of calculating the coefficients KD downtime and KR readiness in case of exceeding the MPC treated water is shown. After analyzing the graphs of water quality indicators, it was determined that the greatest turbidity and chromaticity of the Dnieper water is observed in the autumn.
