Inlet Protection

SCS offers several options for temporary inlet protection and sediment control for all stormwater systems and projects.

Inlet Protection




You can tell it’s a Dandy the moment you open it up. The patented flagship bag is designed to take a lot of hard knocks. Use the Dandy Bag with flat grates (including round) and mountable curbs to filter out all the sediment-laden storm water. The suspended solids are allowed to settle out of the slowed flow and are captured by the Dandy Bag prior to entering the inlet, ensuring you regulatory compliance performance.

Fabricated from a highly visible orange monofilament geotextile so it can be seen in any weather, Dandy Bags provide top of the line inlet protection. They are very easy to install, maintain and inspect. And best of all, they are reusable, to save both time and money.


For a professional strength inlet filter – call in the reliability and durability of the Dandy Curb Bag. Patented and designed for use on curb and gutter inlets, the Dandy Curb Bag filters out the most stubborn sediment-laden storm water. The suspended solids are allowed to settle out of the slowed flow and are captured by the rough and tough Dandy Curb Bag prior to entering the inlet.



Ultra Drain Guard, commonly referred to as a witches hat due to its profile and look. It is made of a permeable geotextile that allows water to pass through but prevents silt and sediment from clogging the drain system. Easy to install and effective inlet protection for your job site.

Blocksom serves as an excellent storm water silt filter at sewer inlets during the construction phase. Blocksom can be cut to any specific size needed, just cut the mat to allow 3” overlap at each side of the grate. Attach the mat to the topside of the inlet grate using cable ties. Clean silt from around Inlet Mat following each rain event. Sweep the top of mat to clear built-up silt and solids.
