“…Moreover, using the MASSCOTE technique (this is the search for a solution to improve irrigation management and operation and better user service) [6][7][8][9][10][11]. The necessary materials were taken from annual reports of the Regional Department of Water Management of the Surkhandarya Region, also irrigation and drainage expeditions.…”

For the 8.2 hectares of the Tupolang hydroscheme near the dam, the measures for its landscaping with the help of a drip irrigation system have been developed. The source of irrigation is infiltration water from the old riverbed. After natural filtration, the water is clear, without mechanical impurities, with a salinity of 0.2 g/l and a flow rate of about 50 l/s. At the end of this pipe, the head is 4 MPa, which eliminates the traditional device of the pumping station to create the required head in a closed irrigation network. This allows the application of these irrigation systems without a pumping station and water treatment. The article presents the initial data for the calculation of drip irrigation: 1. Soils are typical gray soils, non-saline, medium loam by mechanical composition; 2. Groundwaters are at a depth of > 3 m; 3. Mass volume of soils is 1.4 t/m3; 4. Marginal field moisture capacity (MWC) - 28 %; 5. Ultimate moisture capacity is accepted at 85 % of FWP and makes 23.8 %. And most importantly, such irrigation saves water resources.

“…The average decadal actual expenditures to the irrigation system over the past years in these decades were 45.4 and 52.6 m 3 /s, and the maximum was 56.3 and 61.1 m 3 /s. The required consumption according to the water use plan in the Bandyhan canal in the 2nd and 3rd decades of June is 4.9 and 5.5 m 3 /s, and the average decadal consumption of the pumping station at this time is 7.1 and 7.7 m 3 /s (Table 4), i.e., taking into account the planned expenses in the Khazarbag canal and its maximum capacity, it is impossible to skip the additional expenses of the Bandyhan canal during this period, and the pumping station on the 2nd and 3rd decades of June must submit expenses following the plans for the water use of the Bandyhan canal [12]. If we take as a basis the actual average weekly expenses passing through the channels at this time, then the pumping station may not work in the 2nd decade of June and in the 3rd decade of June -with a flow rate of 1.8 m 3 /s.…”

Based on the analysis of the work of the Khazarbagh irrigation system, water use plans, the household regime of the Tupolang River, the operation mode of the pumping station–I, proposals have been developed for the partial transfer of machine irrigation lands to gravity for the zone, the Bandyhan–I subcommand pumping station. With a two–fold accumulation of water in the Tupolang reservoir up to 40-60 million m3 and the use of this water for compensation through the end part of the Khazarbag canal, the distributor P – I in the Bandyhan canal, we recommend turning off the pumping station for the period from February to the first decade of June and from September to November. At the same time, the energy savings amount to 8.38 million kWh.

“…Along the length of the filter (filter frame), sanding wells are covered with soil by 20-80 percent, depending on the amount of silting and the service life. The process of sanding water wells is a problem in different areas in different parts of the world [13][14][15][16].…”

The history of vertical drainage wells began in 1923 in the United States of America and since 1950 in Uzbekistan. Such scientific researchers as N. Reshetkina, Kh. Yakubov, A Umarov, Z. Pushkarev, N. Nasonov, I. Akhmedov, and other scientists worked on designing and constructing vertical drainage wells. The study aims to develop recommendations for improving the sustainable operation of vertical drainage wells based on their design and construction, considering natural and economic conditions. The relevance of the work lies in the fact that stable operation of wells without sanding will provide: an increase in the duration of good operation without repair, an improvement in water supply in the reclaimed area, drainage of the area suspended on the well, and an increase in economic efficiency. The place of research work is the Syrdarya and Fergana regions of the Republic of Uzbekistan, as well as the Kyzylorda region of the Republic of Kazakhstan. The design of vertical drainage wells differs significantly from water wells (for water supply) in that vertical drainage wells are drilled with a large diameter (800-1260mm) and equipped with gravel filters. They have a shallow depth (35-80m) and large diameters of the filter frame and casing pipe (300-426mm), which significantly affect their costs and determine the territory's drainage area, which is the main task of this type of well. Such wells are operated in the study areas. The article presents data that is the basis for developing recommendations for improving the sustainable operation of a vertical drainage well. Recommendations are given to eliminate the problems of vertical drainage wells.
