Abstract:
1. A system for filtering debris carried by stormwater flowing through a gutter inlet and gravitationally therefrom into a catch basin therebelow, the filtering system comprising: a filter device configured in conformity to the gutter inlet to substantially fully cover the gutter inlet exteriorly of the catch basin without passing through the gutter inlet into the catch basin, the filter device being comprised of filtration media selected to prevent passage through the filter device of soil, silt, leaves, sticks, and other stormwater-carried debris, while permitting substantially free passage through the filter device of stormwater, and a separate retainer device for maintaining the filter device in covering relation to the gutter inlet, the retainer device being attached to the filter device and configured to extend through the gutter inlet and to depend gravitationally downwardly therefrom within the catch basin, the retainer device being weighted sufficiently to gravitationally pull the filter device securely against the gutter inlet to resist dislodgement under the forces of stormwater flowing there through.
