Storm Drain Inlet Protection

Definition

Inlet protection includes a wide variety of approaches for trapping sediment through physical filtration and settling processes before it enters a storm drain. There are many options and variations available. Inlet protection is part of a system of erosion prevention and sediment control, and works best when upslope sources of sediment are reduced – primarily by stabilizing bare areas and maintaining perimeter controls.
