Dandy Sack®

Most Reliable Drop Inlet Filter Available

The patented Dandy Sack® provides the best in storm grate filtration quality. The incredibly strong, open-top catch basin silt sack is specially designed to hang below the grate to expertly filter the thickest sediment-laden stormwater. The suspended solids are allowed to settle out of the slowed flow and are conveniently captured by the Dandy Sack prior to entering the inlet, which supports NPDES compliance for runoff water management and storm drain inlet protection.

Unique Benefits of Dandy Sack Inlet Protection

  • Super-easy installation; no rebar required
  • Internal straps add extra support and security on install and removal
  • Manageable two feet containment area
  • Made with highly visible orange monofilament geotextile
  • Available in three standard Dandy Sack sizes to fit a variety of inlets
  • Compatible with optional oil absorbents
  • Compatible with patented curb-filtering technology (See Dandy Curb Sack®)
  • Competitively priced and reusable on jobs needing catch basin sediment control

Nonstop, Regulation-Compliant Performance

Dandy Sack is made of the highest-quality materials available and contains unique design features that enhance its performance. The safety orange monofilament geotextile always looks new, no matter how many times you reuse the product. The suspended solids settle out of the slowed flow and are reliably captured by the high-strength Dandy Sack prior to entering the inlet. This dependable stormwater management solution helps support NPDES compliance and broader temporary erosion control efforts on the jobsite.

Performing the necessary maintenance will keep Dandy Sack working at an optimal level:

  • Remove all accumulated sediment and debris from the vicinity of the unit after each storm event.
  • After a storm event and at regular intervals, look into the Sack. If the containment area is more than 1/3 full of sediment, empty the unit.
  • To empty the unit, simply lift the unit using lifting straps and remove the grate.
  • If using optional oil absorbents, replace the absorbent pillow when it nears saturation.

FAQs About Dandy Sack® and Catch Basin Sediment Control

What is the Dandy Sack used for?

The Dandy Sack is a reusable inlet protection product designed to capture sediment before it enters storm drains. It helps support catch basin sediment control on construction, utility, and infrastructure projects.

Can the Dandy Sack be used as a catch basin sediment trap?

Yes. The Dandy Sack functions as a temporary catch basin sediment trap by hanging beneath the grate and allowing suspended solids to settle out before runoff enters the drainage system.

How does the Dandy Sack support NPDES compliance?

The Dandy Sack helps contractors reduce sediment discharge into stormwater systems, supporting NPDES compliance and broader erosion and sediment control requirements.

Is the Dandy Sack part of an erosion and sediment control plan?

Yes. Many contractors incorporate Dandy Sacks into their erosion and sediment control plan as a temporary inlet protection measure during active construction.

How does Dandy Sack installation work?

Dandy Sack installation involves removing the grate, positioning the bag beneath it, and reinstalling the grate so runoff passes through the filtration area before entering the inlet.
