The President of the Republic of Uzbekistan, Shavkat Mirziyoyev, declared the year 2025 as the "Year to Improve Pump Efficiency" in the water management sector. This decision is an important initiative aimed at improving energy efficiency in the management and use of water resources in our country. In Uzbekistan, 2.5 million hectares of land are being irrigated, with more than 1,600 pump stations consuming 6.8billion kilowatt-hours ofelectricity annually. Unfortunately, 94% of these pump stations have exceeded their normative service life, meaning they have been in use for more than 10 years. This leads to a reduction in their efficiency and results in excessive energy consumption. Under the initiative put forward by our President, the following measures are planned to be implemented: Modernization of pump stations: Reducing electricity consumption by replacing outdated equipment with modern, energy-efficient models. Utilization of solar energy: Diversifying the energy supply of pump stations through the installation of solar panels based on private partnerships and using environmentally friendly energy sources. Construction of small hydropower plants: Accelerating water flow by concreting canals and constructing smallhydroelectric stations,which would generateadditional electricity. If these initiatives are implemented, an additional 600 million kilowatt-hours of electricity could be generated annually. This would not only help save energy resources but also positively impact 514 INTERNATIONAL MULTIDISCIPLINARY JOURNAL FOR RESEARCH & DEVELOPMENT SJIF2019:5.2222020:5.5522021:5.6372022:5.4792023:6.5632024:7,805 eISSN:2394-6334 https://www.ijmrd.in/index.php/imjrd Volume12,issue02(2025) environmental protection. One of the pump stations of significant importance for our country is the Varganza-2 pumpstation. Varganza-2 Pump Station is one of the large hydraulic structures located in the Kitob district of the Kashkadarya region, Uzbekistan. It mainly serves water supply and irrigation systems. This pump station is particularly significant as part of large irrigation systems and plays a key role in providing water to agriculture in the region. The Varganza-2 pump station, which was commissioned in 1991, is designed to lift water to irrigate 360 hectares of land. The water source for the station is the left bank of the Kashkadarya River. The station is equipped with 8 pump units: 4 SN 180-170 and 4 200 D-90 pumps.These pump unitsare powered by5АМ355МВ6еУЗ and АИР-315-S6 motors. The station is primarily used during the spring and summer months and consumes an average of 398,000 kWh of electricity annually. Water supply through the Varganza-2 pump station is crucial for agriculture, especially for managing irrigation systems. This is also essential for the efficient organization of agricultural production in the region. The station plays a significant role in Uzbekistan's comprehensive programs aimed at water resource management, improving energy efficiency, and conserving water inagriculture. Water enters the Varganza-2 pump station from the left bank of the Kashkadarya River through intake chambers. The water is then distributed to 300 hectares of land through 8 pump units (4 SN 180-170 and 4 200 D-90). This process takes place through pressure pipelines and canals. Pressure pipelines carry the water to the canals, wh
