FIELD: hydraulic technology. SUBSTANCE: incoming water from canal 1 is filtered through perforated surface of cylinders 2 and 6 and then along inner cavity of cylinder 6 goes into water intaking waterway. Purification of water is exercised by filter, made of balls 8, located in ring type cavity 7, formed by cylinders 2 and 6, mounted on shaft 4.
