ABSTRACT:
A filter without moving parts is placed in a storm sewer inlet that conveys stormwater flows. The filter is designed to fit a storm sewer inlet and rests on angle iron supports. The supports are attached to the storm sewer inlet walls below the inlet opening so the filter does not pond stormwater runoff in the contributing streets. The filter is composed of a perforated aluminum section riveted to a tubular steel frame. A weir and hydraulic opening for flow conveyance is provided adjacent to the filter. A grate type rack is constructed across the hydraulic opening. At least one handle is attached to the filter on the side of the inlet opening.
