This article presents the results of experimental and analytical studies carried out in the Syrdarya region to evaluate the efficiency of an improved closed horizontal drainage cleaning head. The research focuses on assessing the operational performance, hydraulic efficiency, and resource-saving potential of the newly designed head compared to conventional drainage cleaning systems. The upgraded cleaning head was tested under real field conditions typical of irrigated areas in Central Asia, characterized by high soil salinity, limited water availability, and the necessity for sustainable water management. Experimental findings demonstrated that the improved cleaning head increased operational productivity by 15–20%, while reducing water consumption by 20–25% and energy expenditure by up to 1.2 times. These results confirm that the innovative design ensures more effective removal of sediments and blockages inside the drainage pipes, leading to enhanced system reliability and longevity. Furthermore, the implementation of this improved technology can contribute to more rational water and energy use in agricultural drainage systems. The outcomes of this study provide a solid scientific basis for introducing the modernized drainage cleaning mechanism into large-scale agricultural practice, offering both environmental and economic benefits for sustainable irrigation management in arid regions.
