Abstract

A storm drain filter assembly that filters incoming drainage water and can prevent sediment, debris, and other undesirable materials (such as oil) from entering a storm drain's inlet. The frame can be rotated upwardly away from the road for street sweeping, and can also be detached from the curb and removed to a remote location for cleaning. The filter assembly comprises a filter panel including a bristle filter and a frame that holds the bristle filter, the bristle filter including a plurality of bristles. At least one seal is positioned between the filter panel and the surface to prevent leakage around the edges of the panel. A pivotable mount is provided for holding the filter panel in an operational position in the path of the flowing drainage water. In one embodiment the bristles are made of polypropylene.
