An in-line filter and method for reducing the solids content of a liquid passing through a storm sewer line. The frame of the filter is provided with a screen and optionally, filter media, and is decreased in size until the frame is small enough to fit into the storm sewer line into which liquids carrying solids and pollutants pass. The frame is then expanded into frictional engagement against the inside surface of the line.
