Dewatering Bags

Dewatering Sediment Bags for Sale

Dewatering bags, also known as a dewatering sediment bags, silt bags, or sediment filter bags come in a variety of styles and sizes to fit your project.  Dewatering bags use sturdy non woven geotextile filter fabric designed to catch and contain sediment deposits pumped from your job site’s stormwater discharge (see video below).

We carry sediment filter bags in economy, sediment only, oil/sediment, and reusable models. For a full listing of available dewatering bag options, see:  Dewatering Bags

Dewatering Bag Product Details


The One Clarion dewatering bag is available in a versatile range of styles for construction sites, power plants, and dredging areas. See: Dewatering Bag Product Line Card (pdf)

To determine which dewatering bag model will work best for your location depends on several on-site conditions. Some project factors to take under consideration include:

  • Pump Flow Rate
  • Quantity and Type of Sediment
  • Permittivity
  • Volume of Materials Needing Containment

Keep in mind that the size of the dewatering filter bag you use will be determined by where they are placed. For example, some areas may have size restrictions that dictates what size dewatering filter bag to use. Using dewatering bags in areas with steep slopes is not recommended as the bag may roll from the project location as it fills with sediment. Make sure to not overfill the dewatering filter bag. If overfilled, the dewatering filter bag will burst at the seams and cause damage to the pump.

A dewatering filter bag is designed to help your job site stay in compliance with most local and federal stormwater regulations. All our components meet US Department of Transportation erosion and sediment requirements.

Dewatering Bag Step-By-Step Instructions

Deploying a dewatering bag is a fairly simple process with a few steps, but special care should be taken to ensure the process is done correctly.

The first step deploying a dewatering filter bag is choosing a suitable site for your dewatering bag to sit. This location may be a dump truck, drop box, or if you prefer you can set up the dewatering bag on the ground. If you decide to place the dewatering bag on the ground, you should use a ground cloth to protect the dewatering bag from any debris that could puncture it.

The second step is attaching the hose to the dewatering bag. All dewatering bags designed for sediment or silt control typically have accommodation for hoses up to 6 inches. Once the hose is attached, the silt can be pumped into the bag for dewatering. The dewatering filter bag should be tied securely around the hose once it is inserted.

The third and final step involves pumping the sediment filled water into the dewatering bag. Once the pumping process has started, water will begin to flow out of the bag. This water flow occurs by design using needle-punched fabric which allows water to flow while the silt and sediment is trapped inside.

Dewatering Bag Frequently Asked Questions

The grab tensile strength of our dewatering filter bag is 270 pounds.

The main difference between a dewatering filter bag and dewatering tube is their size and construction. Dewatering bags are a smaller filtration option and are designed for standard dewatering jobs. Dewatering tubes are much larger in size and are used for larger dewatering jobs like wastewater projects requiring sludge removal.
