The research aims to develop new energy-saving modes of operation of the Karshi main canal with a cascade of pumping stations designed to irrigate the virgin lands of the Karshi steppe with water from the Amudarya River. The article discusses some calculation methods and control parametric tests of pumps by measuring the main parameters: flow, pump head, electric motor power, NPSH, and pump efficiency. Normal operation of pumping stations requires compliance with cavitation conditions of pumps of certain levels downstream. The authors have given recommendations on the use of a new floodwater design and obtained the flow's main characteristics in the section under consideration, taking into account the hydrometric characteristics. Further work continues to improve the scheme of water supply facilities by introducing new means of regulating the operation of pumping station elements into the scheme.
