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, authors propose design a well with filters located at two levels, capable simultaneously performing functions working reserve wells, use which will reduce energy consumption for lifting water, capital investments construction ensure uninterrupted supply. The methodology calculating inflow constructing hydrodynamic grids, determining function lowering pressure filtering features during operation two-level in confined aquifer is also presented.
