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.
