ABSTRACT:
The present invention is a storm water filter system for filtering floatable debris and non-floating pollutants from storm water passing through a storm water drain system vault. The storm water filtering system has a vault having chamber having a wall between the inlet thereto and the outlet therefrom. The wall has a filter passageway therethrough for filtering the storm water and a floatable baffle panel covering a second passageway therethrough for capturing floatable debris and trash from the storm water. Storm water entering the vault inlet passes through a filter element and out the outlet and also can pass under the floating baffle panel when the floatable baffle panel is floated to a raised position to thereby prevent storm water from accumulating on the inlet side of the wall.
