Abstract
A drain filtering system is disclosed, comprising a filter placed within a basket which is suspended from frame positioned underneath a drain grate atop the inlet to a storm drain. The filter is constructed from materials which filter out heavy metals and hydrocarbons from the water passing through. The filter also has overflow outlets to prevent back-up of storm water during periods of heavy rain. The basket is constructed from a corrosion resistant material, preferably high density polyethylene which can withstand the extreme pressures exerted by waste and water collected within the filter.
