Two-column two-filter water intake well and the method of its calculation

Boreholes are the most versatile and technically advanced structural type of water intake structures. In this article, the authors propose the design of a water intake well with filters located at two levels, capable of simultaneously performing the functions of a working and reserve wells, the use of which will reduce energy consumption for lifting water, reduce capital investments for construction and ensure uninterrupted water supply. The methodology for calculating the inflow of water, constructing hydrodynamic grids, determining the function of lowering the pressure and filtering features during the operation of a two-level well in a confined aquifer is also presented
