Abstract: The present is basically comprised of a piece of polypropylene woven mesh cut to the size of the catch basin inlet opening grate, of a heavy-duty, partially-resilient rubber open frame member superimposed upon the woven mesh with peripheral butyl rubber adhesive strips, of peripheral butyl rubber adhesive strips secured to the underside of the woven mesh, and preferably a readily removable backing strip contacting the underside peripheral butyl rubber adhesive strip to avoid temporary and inadvertent adhering of the assembly in unwanted places.

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.

Abstract: A novel filter assembly for a drainage system stormwater catch basin is provided with spaced-apart open frame elements that are joined to and carry a singular mesh fabric filter element, and with manually pivotable support leg elements that permit the assembly to be collapsed for subsequent transportation, storage, or refurbishing.

Abstract: A novel filter assembly for a drainage system stormwater curb and gutter-type catch basin is provided with spaced-apart frame elements that are joined to and carry a singular mesh fabric filter element, the mesh fabric filter element advantageously additionally functioning to hingedly interconnect the filter assembly frame elements into a unitary structure.

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 gate. 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.
