DRAINAGE-MOISTENING AMELIORATION SYSTEM Russian patent published in 2004 - IPC

FIELD: agriculture, in particular, complex amelioration of overmoistened agricultural lands.

SUBSTANCE: drainage-moistening amelioration system is ameliorating complex including main channel, drainage and moistening network, and retaining-regulating constructions. Main channel is made in the form of cascade-type channels-sewage accumulators and drain channels, which simultaneously serve as feeding network. Each of channels-sewage accumulators is equipped in its outflow end with automatic downstream water level regulator. Drain channels are provided with upstream water level regulators. Said system allows drainage water of upstream amelioration module to be used for moistening soil of downstream module without employment of special basins-accumulators and water-raising pumping and power equipment.

EFFECT: increased extent of utilizing sewage water for moistening of lands as compared with traditional sluicing systems and reduced consumption of power and contamination of water intake systems with sewage water.
