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 increasing shortage of energy resources and difficulties associated with repairing or replacing pumping equipment requires the search for alternative solutions to machine irrigation of land. This article substantiates the possibility of a phased transition of lands in the Bandykhan district from machine irrigation to gravity irrigation. To save money, the transition to gravity irrigation is planned to be carried out without reconstruction of the canal, obtaining the maximum benefit from water accumulation.
