ABSTRACT:
Debris removing screen basket and overflow apparatus embodiments for use in a storm collection sewer. The device has two embodiments, each including a central panel with foldable wings in each side of the central panel. During initial assembly, the wings are folded up around the central panel for insertion through a manhole cover. Each wing can have an optional extension panel. In the first embodiment, the wings, extension panels and the central panel form a single type panel that is inclined at a variable angle so as to suit various floor conditions at a particular location. Both wings and extension panels have angled deflector top portions, while the central panel does not. A screen mesh basket is supported behind the central panel. Storm water and debris fill up the area in front of the apparatus. The rising water when reaching the height of the deflector portions is forced over the central panel and into the basket. In the second embodiment the central panel and the wings form a ramp chute which angle down from street level into the basket itself. Overflowing water can run around the sides of the filled basket. Filled baskets in both embodiments are removable while the remaining structure is left undisturbed. The baskets can be double levelled where a top layer has larger openings for holding larger debris and the lower tier level can have smaller opening therein for holding sand.
