Dewatering Products

The dewatering bag is the most commonly used dewatering product. Available in a variety of sizes and either 8 oz. or 10 oz. nonwoven geotextile material, dewatering silt bags work well for most dredging and sediment separation applications. The contaminated water is pumped directly into the bag. The effluent flows back out through the material, leaving behind dirt and other large materials inside the geotextile dewatering bag. When the large dewatering bag is 80 percent full, it is ready for transport to a composting area for disposal, depending on the makeup of the contained material.

Geotextile tubes are similar to dewatering bags in purpose and design. The main difference between the two is size and material. Geotubes feature significantly larger specifications, as well as a stronger woven geotextile fabric. For cities and counties, dewatering tubes work well at wastewater treatment plants, filtering contaminants from the local water supply.

In coastal areas, geotextile tubes are a dewatering product that is used for breakwater applications. Many beaches and coastlines suffer from water erosion as strong waves and tides hit the area. Breakwater tubes add an extra line of defense, helping shores retain much of their natural sand. They are available in both black and tan woven geotextile materials, so the tubes can either blend in with their surroundings or have high visibility.

To filter pollutants directly from pipes or hoses, dewatering socks offer an easy solution. The dewatering sock is available in diameters ranging from 4 inches to 16 inches to fit most lines or ducts, and have the smallest dewatering capacity of all the dewatering products. Once clamped around an opening, 5 feet of material catches sediment, silt, and other contaminants before releasing clean water. Dewatering socks work well to filter stormwater as it flows through roof downspouts off municipal buildings. Looking for different erosion control products? See our Erosion Control Product overview.
