Inlet Protection Barrier


SKU MM-DCB-24-24

The inlet protection barriers are proudly made in the USA. These barrier bags install easily and come in a wide variety of sizes to fit your needs. By using the inlet protection barrier you are limiting sediment from going into stormwater and helping to stop backups which could cause damage to your jobsite or residence.

The maintenance is quite simple, as inspectors are reviewing the screens and they start to fill just empty the storm drain debris screen, and then reinstall to be used again.

Having a durable inlet protection solution is going to help reduce damage or further backups to the storm system by preventing larger debris from getting lodged in the curb inlet.

Installation and Maintenance Guidelines


  • The empty Dandy Curb Bag should be placed over the grate as the grate stands on end.
  • If using optional oil absorbents, place absorbent pillow on the bottom of grate pouch.
  • Attach absorbent pillow to tether loop.
  • Tuck enclosure flap inside to completely enclose the grate.
  • Holding the lifting straps (do not rely on lifting straps to support entire weight of grate), place the grate into its frame (street side first), then lower back edge with dam into place.
  • When properly installed, the Dandy Curb Bag should be partially blocking curb hood.
  • Maintenance:

    • Remove all accumulated sediment and debris from the surface and vicinity of the unit after each storm event.
    • Remove the sediment that has accumulated within containment area of the Dandy Curb Bag as needed.
    • If using optional oil absorbents, remove and replace absorbent pillow when near saturation.

What You Should Know About Inlet Protection Barriers

Improve The Control Of Sediment Using Inlet Filters

To start with, inlet filters will control the level of sediment by trapping it. That's the sole purpose for the existence of Inlet protection barriers. These inlets are actually temporary solutions when soil is disrupted. Inlet filters are designed to keep soil out of storm drains when it's raining.

These barriers and filters are very important to protect the drinking water that's used in cities. They keep silt from getting into inlets, storm drains, and recovery channels. Where there is construction, there is soil disturbance and these filters must prevent construction debris from coming in contact with groundwater. The filter allows water to pass through a small opening to prevent silt, debris, and dirt from entering groundwater, no matter how slow or fast the water flows.

What Kinds Of Inlet Filters Are Available?

Based on rainfall and flooding, there are different current speeds, slow, medium, and fast. Therefore, these filters come in different kinds of surface filters to choose from to meet your needs. Also, there are surface curb filters used for larger projects such as basins.

Another kind of stormwater protection is an inlet tube that is either weighted or non-weighted. The weighted variety does not require stakes to support them. They are normally placed on top of surfaces like gravel or asphalt as well as other hard surfaces. They are perfect for construction traffic around an opening where water might enter. The non-weighted tubes are good for other types of settings, such as grass or brush, and are tied down with stakes.

Creating a barrier of porous fabric placed around an inlet will create a shield to prevent sediment while allowing water to flow through the drain. There are certain filters designed to catch certain industrial and commercial pollutants including hydrocarbons and metals, while others catch contaminants before moving water directly into ground aquifers. Even though there are many different kinds of inlet filters, it's recommended to consult with an expert before finishing up a project to ensure you have the correct match. There are several protection companies with the experience to guarantee that construction projects are CWA compliant to prevent costly fines assessed by state inspectors.

Prevention Steps At Active Construction Sites

Sediment and erosion control play important roles at construction sites for maintenance and inlet protection. Good prevention measures to control runoff and protect the surrounding environment. There are several methods for preventing sediment runoff and erosion control, and each has its own use and place. When prevention, collection, and decontamination are working together, they can be very effective in decreasing or getting rid of the effects of sedimentary runoff along with erosion and chemical contamination on construction sites.

Preventing Erosion And Sediment Runoff

Preventing runoff is first and foremost in protecting these construction sites including applying gravel over the dust and dirt for vehicles as well as heavy equipment to drive on. A gravel driveway will cover dust and dirt and not disturb it but will reduce erosion. Also, gravel-protective textiles can cover the ground and stop other elements like dust from becoming dislodged leading to erosion.

Grading the surface is effective for controlling erosion, the runoff of sediments, and collecting erosion. Despite all the steps taken to stop sediment runoff and erosion, there will always be some instances taking place on construction sites.

In order to handle these situations, it's important to safely collect sediment that collects from erosion in order to prevent it from entering the storm sewers. There are several avenues you can take to get what you need. Silt fences are effective tools for collecting sediment runoff. These fences are installed and serve as filters to strain out sediment and debris that is washing down toward the fence. Consider using an inlet filter to protect the inlet. You can get these filters in a roll or something that resembles a fabric sling that hangs below the inlet collecting debris and sediment runoff before entering the waterway.

These filters are environmentally friendly and used many times. They are easy to install, maintain, and remove when the job is done.

Sediment Runoff & Erosion Chemical Contamination

There are other reasons for protecting water from chemicals that are present at active construction sites. These chemicals come from water runoff, accidental spills, or from by-products used on the site. Most inlet filters come with a chemical absorbent pad that can be inserted into the filter. The pads must be monitored and changed out for maximum protection from chemical contamination and are very effective when used the right way.

In Conclusion

Inlet filters are excellent products for controlling erosion and sediment runoff, especially on construction sites. Not only are they environmentally friendly but are a chosen product for many uses on construction sites as well as other projects. Controlling sediment is the biggest reason why these filters were created. Preventing runoff is critically important for many projects, for construction sites, and is good for the planet.
