Abstract
A drain filtering system is disclosed, having 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 that filter out heavy metals, sediments, debris and hydrocarbons from the water passing through. The system includes a riser tube having an inlet and an outlet, where the inlet is positioned inside the filer, and the outlet is positioned external to the filter. The inlet is placed close to the top of the filter to allow a bypass fluid path for periods of high flow.
