Claim:
A storm water filtering system located in a storm water catch basin, the basin having a storm water inlet spaced from at least one storm water outlet and defining a chamber for storm water collection between the inlet and the outlet, the filtering system comprising: a plate for dividing the basin into a first chamber for receiving storm water and a second chamber for passing storm water out of the basin; a filter assembly mounted within a hole formed in the plate, the filter assembly including a filter media having a predetermined effective flow rate for removing pollutants from the storm water; an overflow tube coupled to the plate at another hole formed therein for passing storm water through the plate and bypassing the filter assembly, the overflow tube having a storm water inlet at a height above the filter media so as to limit the maximum water pressure applied to the filter media; and a diverter lid mounted to a top of the overflow tube, the diverter lid having downwardly depending sides spaced from and overlapping the storm water inlet in the overflow tube such that pollutants floating on a surface of the storm water when the storm water is above the level of a lower edge of the lid sides cannot enter into the overflow tube.
