The article describes the main factors affecting the rise in the level of groundwater in the city of Fergana and ways to eliminate them. Currently, in order to reduce the negative impact of rising groundwater levels on the environment, crops, buildings and structures, as well as underground utilities, it is proposed to design horizontal drainage in urban areas and a mathematical model has been developed for changing the groundwater level. For this, long-term data from observation wells were analyzed and the hydraulic parameters of horizontal drainage were selected taking into account the hydrogeology of the area. Taking into account the terrain and characteristics of the soil layers, the possibility of diverting the collected water outside the city through the "Margilan Say" passing through the city center has been developed. This equation is solved by a numerical calculation method, and the results are presented in the form of a 3D graphic mode, where the change in the groundwater level is presented in different colors. Based on numerical solutions and analysis of data from observation wells, it is shown that the groundwater level can be lowered due to horizontal drainage. The adequacy of the results was assessed by comparing data collected in natural field conditions.
