The article presents the results of a reliability study, where violations of work are determined based on operational data to create a database for determining reliability indicators and the characteristics associated with them. The numbers of accidents, failures and defects of pumping units of the Namangan pumping station over a 5-year period are shown, and the values of the intensity of the occurrence of the event were calculated. By the method of statistical analysis of the safety of technical means at the stage of operation and analysis of the potentially emergency sequence, the most dangerous scenarios of the types are identified, the sequences of danger, causes, consequences and parameters to be monitored are determined, which will be useful for determining reliability, calculating risk and assessing the safety of pumping units and the pumping station itself. Taking into account that the uptime of pumping units of the PS of machine irrigation is distributed exponentially, the values of the probability of initial events are calculated and graphs of changes in the probabilities of initial events of work for 5 years, as well as work for 60 years PU are plotted.
