ABSTRACT:
A filter for removing particulate matter from water flowing into an inlet, such as a catch basin is disclosed. The filter may comprise an envelope of filter material adapted to receive an inlet cover device, such as a catch basin grate. The inlet device may be inserted within the envelope and placed in an opening of the inlet. Water, for example, may then be double filtered before entering the inlet. A roll filter comprising porous material is also disclosed that may be used in combination or alone when filtering runoff entering a curb drain or other inlet.
