PURPOSE: A settling tub for multiple filtering is provided to considerably delay a blockade by selectively filtering adulterations corresponding to a pore size of a filtering net, to effectively remove the adulterations in flowing water by settling sand, etc. which are heavier than water on a screen supporter by a reverse-siphonage type waterway. CONSTITUTION: A settling tub for multiple filtering comprises a bottom part(200), an exterior wall(300), multiple partition walls(400), a filtering part, and a cover part. The exterior wall is installed in the left and right sides of the bottom part. The multiple partition walls are installed in between the exterior walls installed in the left and right sides. The filtering part comprises multiple filtering tubs installed in between the partition walls, and multiple filtering nets(520) installed in the multiple filtering tubs. The cover part covers the upper part of the space between the exterior walls. The size of a sieve of the screen installed in the filtering net becomes smaller to the downstream.
