FIELD: irrigation and drainage construction and agronomy, particular, development of deserts and near deserts. SUBSTANCE: amelioration system for agricultural development of deserts and near deserts has prefabricated reinforced concrete water reservoir buried in ground and rectangular in plan, and column net square in plan or rectangular. Columns have backing waterproofing of side surfaces. Side walls and concrete bottom consists of concrete base and water seal. Concrete floor is made with cement covering and floating with cement. Reservoir covering is made of cross bars laid over columns and T-shaped girders located on cross bars with clearances between their external flanges. provided in girder clearances are inverse gravel filters above which three layers of fiber glass fabric are located. Sand layer is poured over fiber glass fabric. Bowls collection of condensate are installed in the lowest part of sand layer. Laid above bowls in the upper part of sand layer are water cooling pipes for more effective formation of condensate. Placed over sand layer is layer of vegetable soil. Supplied to the lower part of reservoir is water of any salinity and laid in its mass are pipes for water heating of salt. water. EFFECT: higher efficiency. 2 dwg
