Drilling wells for water in one column, truboy 90mm, 110mm and 125mm

Execute this structure drilling Verhovodny, Kanevskii, Kharkov, Poltavsky Buchansky Cenomanian aquifers and from 10 to 130 meters and the field in Kiev
wells with a diameter of 90mm casing, develop submersible pumps.
When high dynamic level wells can be installed pump station
wells Pros executed under subsurface pump (diameter 90 mm), consist in the possible access of different instruments to requiring repair or preventing the borehole.
Performance borehole zhin diameter of 90mm is much higher than that of the well with a filter column 50 mm, due to a larger diameter and possible height adjustment of downhole pump assembly.
