Sediment Control & Inlet Protection

TURBIDITY BARRIERS OR FSC UNITS (FLOATING SILT CURTAINS)

Turbidity curtains and floating silt curtains are used to control the release of silt from a construction site. The curtains float in the water and form a barrier to the silt. Different styles of turbidity curtains are available for specific applications and flow rates.

Fixed and floating baffle curtains are used to direct the flow of water to increase the residence time in a pond or reservoir. Fixed baffles are typically bolted to the inside of concrete water reservoirs while floating baffles are typically placed in wastewater treatment ponds. Specialty can assist you with selecting which curtain is right for your job specific application.

DANDY BAG 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.

DANDY CURB BAG

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

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 jobsite.

Georidge

GeoRidge is a lightweight, sustainable alternative to conventional check dams. GeoRidge is a permeable plastic berm that has been designed for erosion and sediment control. It can be used with both permanent and biodegradable erosion blankets and is effective in reducing water velocity, spreading water over a wider area, trapping sediment, and aiding in revegetation.

DEWATERING BAGS

Specialty carries a variety of sizes of dewatering bags that detain both oil and sediment, offering a combination of benefits not available in alternative dewatering bags. Our dewatering bags accommodates up to a 6” discharge hose, and they help comply with NPDES, 40 CFT 122.26 (1999) when used as a BMP in SWPPP’s.

Sizes available:

  • 6’ x 6’
  • 10’ x 15’
  • 15’ x 15’

Blocksom

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.

Inlet Filter Installation Instructions:

  1. Remove sediment, debris, ice and snow from the inlet grate surface and surrounding area.
  2. Verify fit by placing filter over inlet grate to ensure that Inlet Filter extends at least one inch beyond the front and both curb ends. The overlap slows water flow and starts
  3. filtering sediment and debris before water drops into the inlet.
  4. Position the mat. Place Inlet Filter on grate with the net side down, flush to the back edge and extending beyond the grate opening on the front and both sides. The zip ties attach Inlet Filter to the inlet grate cover WITHOUT LIFTING THE GRATE COVER.
  5. Insert zip ties. Lift Inlet Filter slightly to enable you to see the first grate bar from the edge of the grate cover. Push the zip tie down through the Inlet Filter and loop under the grate bar. Insert the pointed end of the zip ties about 2″ away from the first zip tie penetration and push back up through the filter. Push the pointed end of the zip tie into the receiving end just enough to hold ends loosely. LEAVE ZIP TIES LOOSE UNTIL ALL TIES ARE LOOPED THROUGH THE MATS AROUND THE GRATES. Repeat Step 4 until all zip ties are installed loosely.
  6. Tighten zip ties. After attaching all of the zip ties, re-position Inlet Filter to completely cover and overlap the grate. Pull free end of zip-ties hand tight to anchor Inlet Filter to the grate. Cut off free end of zip ties to leave a 1″ tail.

Inlet Filter Maintenance Instructions:

  1. Inlet Filter will collect a lot of sediment. Clean Inlet Filter while mounted on the grate, even if ponded water surrounds the inlet. This unique feature ensures all water entering the grate is filtered. Sweep sides and top of Inlet Filter to remove sediment and debris after each rain event.
  2. Remove sediment from the sides of the filter by sweeping away from Inlet Filter.
  3. Remove sediment from the top of the filter by sweeping off of Inlet Filter.
  4. Inlet Filter is prepared for the next rain event.
