IRRIGATION SYSTEM WITH WATERING OF SLOPES FOR CLEANING OF SEWAGE WATERS Russian patent published in 1999 - IPC

FIELD: agriculture. SUBSTANCE: irrigation system has sewage water pipelines and clear water pipelines, sewage water mechanical cleaning constructions and reservoir basin. Watering blocks are created on slope with natural biological cleaning area. Watering blocks are restricted by longitudinal windrows defining passages having profile suitable for traveling of farm machines. Water distributors and irrigators with sewage water supplying constructions are built for supplying sewage water to watering blocks. Slopeless channel of profile suitable for passage of farm machines is used as distributor for distributing sewage water over biological cleaning area. EFFECT: increased efficiency in cleaning sewage water from soil, reduced production costs by eliminating water distributing pipeline and water accumulating vessel from irrigation system, and provision for further utilization of sewage water. 3 cl, 3 dwg
