FIELD: construction.
SUBSTANCE: invention is related to agriculture, namely to land drainage, and may be used in creation of pilot-plant section for performance of field tests of experimental drainage systems in it. Drainage system on pilot-plant section includes experimental drainage systems - versions of R replication with n quantity of experimental drains connected to closed header that falls into inspection well that communicates to closed transit header installed deeper than closed header by at least 0.5 m, at that every experimental drainage system is equipped with identical experimental contour drains that fall into inspection well. Closed header of every experimental drainage system and closed transit header are made of pipes with water impermeable walls without joints and water receiving holes.
EFFECT: increased validity and accuracy of field survey of experimental drainage systems efficiency.
