The article analyzes the structural solutions and main functional elements of horizontal drainage that ensure the efficient operation of drainage systems at reconstruction sites, especially with low-permeability mineral soils and the presence of drainless depressions. The high filtration properties of synthetic filter materials, which make it possible to significantly increase the waterreceiving capacity of drainage pipes and replace with them the filling of drains with sand and gravel mixture, sand, etc have been considered. A set of measures is recommended using drainage devices that are at the stage of patent solutions, including new elements of the drainage network made of polymer materials that serve to remove excess water from closed depressions. Measures are proposed that increase the intensity of water drainage from excessively waterlogged lands, which provide conditions for highly productive agricultural production.
