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 dewatering 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 specially engineered, stronger woven geotextile fabric. This provides superior containment of fine solids and more clean water flow rate. Dewatering tubes are available in 22' to 200' lengths with circumferences up to 120'. Dewatering tubes work well for cities and counties at wastewater treatment plants, filtering contaminants from the local water supply.

In coastal areas, geotextile tubes are a perfect solution 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.

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.
