FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used in the melioration of slightly sloping lands with characteristic seasonal freezing and heavy underlying rocks capable of forming temporary aquifers in the form of perched water. The system includes drains of the upper and lower tiers, connected to closed collectors, respectively, of the upper and lower tiers of drains, the mouths of which are interconnected and communicated with an open channel. The drains of the upper tier are curvilinear with a constant radius of curvature equal to half the distance between the drains of the lower tier, equipped with source wells and conductive wells located between them, connected to a closed collector of the upper tier. The mouth of the closed collector of the lower tier at the junction with the wellhead part of the upper collector is equipped with a hydraulic valve that cuts off the lower tier from the upper one.
