The Regular Flow Siltsack is a sediment control device designed for drop inlet filters. The Siltsack is made of a permeable geotextile that allows water to pass but prevents silt and sediment from clogging the drain system. Siltsack can be used as a primary or secondary sediment control device and must be maintained on a regular basis to function properly. Optional overflow holes are offered to make the Siltsack effective even in the most extreme weather events. Although it's considered a temorary solution, this cost-effective product can be emptied and reused throughout the duration of a project.
