Increasing the productivity of a water intake well by changing the diameter of the filter part

This paper presents research data on increasing the flow rate of a water intake well. The well was drilled in sandy soil. A filtration element was used. The source was more than 45 m deep. Two-column wells were chosen as the basis. Wells of this type are drilled on rocks of quaternary deposits (sand). In this design, a coarse filter was used, which is a perforated pipe covered with a filtered mesh. The aim of the work was to achieve maximum water recovery of the aquifer from a two-column well by increasing the area of its filter part to provide water for capital construction projects. The results of the study showed that for rocks of quaternary sediments (sand) with a two-column well system, increasing the diameter of the filter part to the maximum (168 mm) increases the flow rate by 82,2%.
