At first glance, a storm drain cover appears to be merely a protective grate installed over a drainage system. However, its primary function is to prevent debris, leaves, trash, and other pollutants from entering the storm drain system.

By filtering out larger waste materials, storm drain covers help maintain the efficiency of the drainage system.
