Abstract: A self-relieving curb inlet filter, for intercepting debris, to be positioned in the opening of conventional pre-cast and cast-in-place curb inlets, for reducing water pollution in lakes, rivers, streams, and oceans. The present invention is one-piece molded apparatus with screened grid configuration of vertical and horizontal members spaced to allow liquids and small debris to go into the storm sewer system while intercepting large sized debris. The present invention permits accumulated debris collected to be released into the storm sewer system, usually during heavy rainfall events, when flow/debris pressure, against the present invention, increases sufficiently to move/open the present invention. The present invention moves/returns to the original position when flow/debris accumulation pressure decreases from the present invention.
