Trash screen

Trash Screen

Trash screens trap larger debris to keep it contained within the sediment trap. This prevents debris from accumulating in vegetated areas and smothering plants needed for the facility to function as designed. Make sure trash screens, also called debris barriers, are maintained annually so stormwater can flow through your facility properly. A trash screen is often part of a sediment trap, which you can learn more about here
