ABSTRACT:
A combination filtration and anti-microbial catch basin filter disposed in a catch basin of a storm water system such that, in addition to removing particulate matter and other contaminants, the concentration of bacteria in storm water that remains resident in the sump of a catch basin after a storm event is severely reduced or eradicated. The catch basin filter comprises a filtration bag depending from the opening such that water must pass through the bag and a plurality of strips or similar members depending from the filtration bag, the length of the strips being such that they remain in contact with water resident in the bottom of the catch basin. In an alternative embodiment, the device comprises a floatation member with filtering means and anti-microbial strips depending therefrom.
