Inlet Protection (Frames and Filters)

Catch Basins are an integral part of stormwater control and drainage systems. The purpose of a catch basin is to catch debris and release stormwater from a parking lot, street, highway, or landscaping area. During project site construction, sediment, pollutants, and trash must be prevented from entering the surrounding streams and wetlands, which feed into our watersheds. Inlet protection frames and filters, also known as rigid inlet protection, are designed to be a temporary sediment control device during land disturbing construction activities. Inlet protection frames and filters are a performance-based, cost effective replacement for drop inlet filtration BMP methods such as: silt fence boxes or rock and wire inlet protection.
