Sediment trap

Sediment Trap

Sediment traps allow fine dirt particles to settle before entering your stormwater facility. This preserves the functionality and lifespan of the facility by preventing sediment from accumulating in the planted area. Make sure sediment traps are maintained annually to keep your stormwater facility functioning properly.
