On 10 May in Tashkent, due to intense precipitation, reports of flooding were received from 23 addresses in eight districts of the city, the Tashkent city administration reported. The highest number of reports was recorded in the Mirzo-Ulugbek district (6 addresses), followed by Shaykhantakhur (4), Yashnabad (3), Mirabad (3), Almazar (2), Chilanzar (2), Yunusabad (2), and Yakkasaray (1).

According to relevant services, the amount of precipitation on 10 May totaled 35 mm, with a significant portion falling in less than two hours—more than half of the average monthly norm. For comparison, Tashkent’s current stormwater drainage system is designed to handle up to 20 mm of precipitation per day, while the master plan provides for a phased increase in capacity to 36 mm per day. During the period of the heaviest rain, the infrastructure experienced a short-term load close to the projected design parameters, which in certain locations caused the instantaneous volume of water to exceed the capabilities of the existing irrigation networks and pipelines, resulting in water accumulation in a number of areas.

It is also noted that in some locations the situation is aggravated by local factors: clogging of drainage elements with trash, unauthorized constructions, as well as the covering of aryks and irrigation systems for parking or other хозяйственные needs. To promptly eliminate the consequences, specialists and crews from emergency services, drainage-collector systems, canals, municipal services, and other relevant organizations were deployed; more than 60 units of specialized equipment were working on site. As a result of the measures taken, the consequences of the flooding were fully eliminated within an hour.

For each address, working groups conducted an initial assessment of the situation and identified the necessary measures. Among the solutions under consideration are the installation of an irrigation system at 5 addresses, a повторное review of one site jointly with designers, the installation of 3 additional siphons, the installation of 800 mm diameter pipes at one site and 500 mm diameter pipes at a number of other locations, the installation of additional pumping units and an increase in drainage capacity, the installation of 6 additional stormwater inlet grates, as well as increasing the throughput capacity of certain sections of the system. Work is planned to continue on an address-by-address basis, with an emphasis on the phased modernization of the stormwater drainage infrastructure and reducing the risks of локальные flooding.
