The results of studying the operating modes of siphon catchments on the drainage and irrigation system of vertical drainage in the Polesie region in order to determine the conditions for the stability of their operation have been described. The parameters of the studied siphon catchments and the factors affecting its stable and stable operation, especially the amount of air entering the pipeline, are given. Minimum allowable water velocity in siphon is set to
ensure its stable operation without air removal. The zones of influence of the siphon catchments on the position of the groundwater level and the contours of the drained area during the operation of linearly located wells were determined. Conclusions were made about the possibility of using siphon catchments in modern conditions as structural elements of vertical drainage in certain hydrogeological conditions.
