Zusammenfassung:A stormwater drain insert (10) includes a top bib (20) having an adjustable frame (12) with a central sediment bag (30) extending downward from a central opening of the top bib (29). Overflow ports (36) are provided in the sediment bag (30), and an inwardly extending overhang ring (34) directs incoming water flow away from the overflow ports (36) as it enters the sediment bag (30). The top bib (20), sediment bag (30) and overhanging ring (34) may be made of water permeable oleophilic fabric that helps trap oils and other hydrocarbons.
