The article describes water wells of new design which are equipped with pipe regeneration systems and backfilled with clay sand. The wells are drilled at the water intake "Felitsianovo" in Minsk in 2015. The strength of the circulation pipes of wells regeneration system under ground pressure is calculated for the worst case on the example of the well number 3. Water absorbing ability of pipes was tested during natural hydraulic experiment both results of this experiment and technological recommendations for wells repair are presented.
