Abstract: A filter system for insertion into a storm drain pipe for filtering liquid runoff. Storm weather or other runoff will filter through this filter system prior to this runoff passing through to the outfall and into oceans, lakes, streams, ponds or other retention areas. The filtration system fits within the storm drain underneath the manhole and will capture all the runoff. The filtration device contains a stainless steel flange which hinges into the storm drain and a main chamber which extends down into the storm drain containing a series of filter chambers. The first level of filtration the hydrocarbon media can be easily replaced once saturated. An overflow opening is located at the upper portion of the liquid capturing chamber which prevents backflow with excessive runoff.
