Purpose: to determine the main directions of the automated control system modernization for the water intake workload distribution in the village of Pavlovka, Orenburg region. 

Materials and methods. An engineering and technical solution to the problem of increasing the efficiency of the technical water intake system based on the optimization of the control system of the 2nd lift pumps was obtained: float level sensors in water storages are replaced by ultrasonic ones and frequency converters are installed on all 2nd lift pumps, the pressure sensor is transferred from the pipeline to the water column of the water tower, feedback is provided by the industrial logic controller PR100 OVEN. 

Results. An engineering and mathematical model of the workload distribution system through the water level control system in water intake storages was built in the form of a generalized transfer function of the system, it was verified in the SimInTech dynamic modeling environment, and the estimates of the qualitative indicators of the automated control system before and after modernization were obtained. 

Conclusions. The main calculations were performed using the author's software for assessing the quality indicators of linear dynamic systems and showed an improvement in response time due to a decrease in the control time from 15 to 6 s, an increase in the degree of stability from 0.2 to 0.5, and an increase in the system reliability by 10.3 %. All these changes do not affect the stability of the control system, but increase the efficiency and functionality of the technical water intake system. The performance of the 2nd lift pumping station is considered as an indicator of the modernization effectiveness. The calculations carried out using the author's software for assessing the economic efficiency of the technical system modernization show an increase in the expected productivity by 88 %. The expected payback period for the modernization will be 19 months.
