Abstract

A removable storm drain cartridge to preserve the ground water quality to improve the environment for separating storm run-off water and removing oil and heavy debris from the storm run-off water, conveniently and inexpensively for use in a conventional storm drain, the cartridge including a heavy duty rectangular box container that is waterproof, an interior passage that is smaller in cross-sectional area that covers the top opening, forcing all storm water to flow through the interior passage first, the interior passage having a shortened length relative to the container length so that water flow will be out of the interior passage up the side walls of the exterior container out through openings in the top of the side walls. An oil trap is strategically located across the opening of the container to catch oil particles and remove them from the water flowing therethrough, while rocks, sand, and other debris will collect in the bottom of the container. The container can be periodically removed from the storm drain and emptied, preventing build-up of debris and oil within the storm drain.
