FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular, to complex melioration of waterlogged agricultural lands. System includes drains (3), collectors (2) and cascade of filtering wells (4), serially connected by pipeline network (5), with discharge of excess drainage effluents to accumulation pool (1). Pipeline network (5) includes slide gates (6). Filtration wells (4) have filtering cassette consisting of settling zone from 0.1–0.3 m and filtration zone, which is a frame with parallel connected stainless mesh with mesh sizes of 0.04–20.0 mm with pitch of 0.1 m with filling of cavities with catalytic sorbent of aluminosilicate with packed density of 1,350–1,400 kg/m3.
EFFECT: accumulation of drainage water in each section and use of sprinkling equipment without risk of clogging nozzles and water-conducting belt.
