A gross pollutant trap (50) to be installed in a storm water channel so as to receive storm water flowing through the channel and to filer gross pollutants from the storm water. The trap (50) includes a gross pollutant collection area (61) toward which there extends generally parallel sets (63) and (67) of vanes (64) and (68). The area (61) is at least partly defined by a mesh wall (72) through which water returns to the storm water channel.

1. A gross pollutant trap to be installed in a storm water channel, said trap including:a channel pardon to receive storm water from the storm channel and to return to the storm water channel storm water from which at least some gross pollutants have been removed, said channel portion including a floor from which there upwardly extends a first side channel wall on one side of the channel portion and a second side channel wall spaced from said first side channel wall so that said floor is located therebetween, said first side channel wall including a downstream portion; a collection area adjacent said first channel wall, said collection area being adapted to receive gross pollutants removed from storm water delivered to the pollutant trap; a first set of vanes extending upwardly from said floor at a position upstream of said collection area, said first set of vanes being arranged in a row which is generally linear and extending downstream from said second wall at an acute angle thereto towards said first wall but terminating at a distance spaced from said first wall; a second set of vanes extending upwardly from said floor, said second set of vanes being arranged in a row which are generally linear, said second set of vanes extending downstream at an acute angle to said second wall but being spaced therefrom and extending toward said collection area; a drainage wall of expanded metal mesh extending upstream from said first wall downstream portion to a downstream portion of said second set so as to least partly define said collection area so that water may flow from said collection area through said drainage wall to be delivered to said storm water channel; and wherein said first and second sets of vanes are spaced but overlap relative to the general direction of flow of water through the channel portion and direct water to said collection area.
