Sardoba Reservoir is a water storage facility located in the Sirdaryo region of Uzbekistan. It was built in the area traversed by the central canal of the Southern Mirzachul aqueduct in 2017. The construction of the water reservoir began in 2010 and was completed in 2017. Its purpose was to utilize the fertile lands of Sirdaryo and Jizzakh regions and increase the crop yields of rural farmers. The creation of a catchment area around the reservoir was also considered during the construction phase. The construction of the water reservoir involved the participation of more than 10 subcontracting companies, including "Sirdaryo Water Construction Invest" JSC (under the Ministry of Water Economy), "UzGip" LLC (designer), and "O'ztemiryo'lqurilishmontaj" JSC (main contractor for Uzbekistan Railways). The management and development of the Sardoba Reservoir is under the supervision of the "Directorate for the Use and Development of Sardoba Reservoir Objects" under Uzbekistan Railways. The total cost of the Sardoba Reservoir was 1.3 trillion Uzbekistani so'm (equivalent to 404 million US dollars). On May 1, 2020, the Sardoba Reservoir dam was breached, causing flooding in ten populated areas in the Sardoba, Akaltyn, and Mirzaobod districts of Uzbekistan, as well as the Paxtaorol district of Kazakhstan. HPS Project On April 21, 2020, the construction of the HPS began at the Sardoba Reservoir by Uzbekhydroenergo JSC. The cost of the HPS construction, which is estimated to be completed in 2023, is 21.3 million euros and will be financed by Russia's Roseximbank. The Russian company "Silovyye mashiny – ZTL, LMZ, Elektrosila, Energomasheksport" is the main contractor, and a contract worth 19.2 million euros was signed with them. According to the project, the HPS will have a total capacity of 10.7 MW, with two hydro turbines generating 5.35 MW each. The annual electricity production capacity of the HPS is expected to be 41.1 million kWh. Flood On May 1, 2020 at 05:55, water started overflowing from the 6th picket wall of the Sardoba reservoir, and the water flow gradually increased.
