Purpose: development of constructive solutions for water intake structures for water withdrawal from watercourses, its preliminary treatment from mechanical pollutants and further delivery to drip irrigation systems.
Materials and methods. The information base for the study was the survey data of existing water intakes and suggestions found in the patent search for constructive solutions for water intake structures from flumes and its delivering to the water supply network of drip irrigation systems. When developing reclamation water intakes designs, methods of scientific analysis of existing and proposed structural solutions were used and search design technologies were used in developing structural schemes.
Results. During the inspection of existing water intakes, their low efficiency in preliminary water treatment from mechanical pollutants which leads to intensive pollution of water treatment facilities that are part of the drip irrigation system was stated. The task of a higher degree of water treatment from pollutants at the intake can be solved by the use of water-filtering elements in the intake units and structures. Two structural solutions of water intake heads preventing the weeds of a given size from entering the pipeline drip network on the base of filtering panels have been proposed. In the design of the proposed water intakes, it is supposed to withdraw water from the least polluted horizons of water courses, to purify it by filtering and also replace or clean the filtering elements from the accumulated litter on their surface.
Conclusions. As a result of the study, two water intake designs from surface water bodies based on the use of filtering panels that provide a given level of water treatment from mechanical impurities for its subsequent delivery into the piping network of drip irrigation systems were proposed.
