The article analyzes the hydraulic and energy-related problems that arise during the pumping of muddy water flows at pumping stations of the Amu Darya and its associated irrigation systems. The influence of sediment particles on flow parameters, specific hydraulic resistance, and pump operating efficiency is theoretically substantiated based on the law of conservation of energy. Formulas for determining head losses for finely and coarsely dispersed muddy mixtures, as well as the concept of critical velocity, are presented. Using a specific example, the head characteristics of a pipeline system under clean water and muddy water conditions are compared, and the increase in electrical energy consumption at a turbidity level of 5% is calculated. The obtained results are of practical significance for selecting optimal operating modes of pumps and reducing energy consumption.
