Abstract
The invention relates to a removable filter for buried catch basins. The filter includes a bag located below grade level in the catch basin and looped flaps which extend above grade level and aid in removal of the filter from the catch basin. The filter is held in place in the basin by a heavy grate which rests on the flaps. The flaps extend at grade level away from the grate. The filter is removed from the catch basin for dumping by inserting a lift rod in each flap loop and hooking lift chains to the rods at openings in the loops.

The combination comprising:
- a) a catch basin including,
- i) an inlet through which water and solids flow into the catch basin,
- ii) an outlet through which water flows out of the catch basin, and
- iii) basin sidewalls;
- b) a catch basin filter including,
- i) a filter bag in the catch basin for capturing the solids which enter the catch basin through the inlet, said bag having an open top at the catch basin inlet, a closed bottom and bag sidewalls, and
- ii) a plurality of elongate lift flaps joining the top of the bag and extending across the sidewalls at the catch basin inlet, loops in the flaps away from the bag and spaced openings in the loops;
- and
- c) a grate on the catch basin overlying the catch basin inlet, portions of the flaps between the filter bag and the loops extending between the grate and the catch basin inlet so that the grate sandwiches the flaps in place against the catch basin and the flaps support the bag in the catch basin.
