Sediment Control Products – The Role of Dewatering Bags for Silt
Dewatering a construction site is something that is almost always required. The dewatering process involves removing the groundwater from the site through pumping or evaporation. Dewatering is usually performed before excavation begins so the groundwater table is lowered to an appropriate level. Most construction sites need dewatering to remove the water that builds up in trenches, excavations, or in areas that have an insufficient slope. The water must be removed from the construction site to keep the project running smoothly and more importantly, for safety reasons. Pumps are commonly used for dewatering but, if not done correctly, can lead to erosion and pollution problems when discharging the water and the sediment that inevitably comes with it. This is why sediment control products such as dewatering bags for silt are so important for the dewatering process.
Dewatering Bags for Silt
Dewatering bags for silt are made from strong and durable geotextile fabric to ensure high-quality performance. They are used on dredging operations, construction sites, or places that have a high water table near a shoreline. Dewatering bags for silt control sediment discharge when pumping water from a construction site. As the water is pumped through the dewatering bag, it is slowed down which allows the bag to capture the sediment as the water flows through the bag. Once the process is complete, the dewatering bag can be opened and the sediment can be discharged in a safe and responsible way.
The dewatering process is something that makes a jobsite much easier and much safer to work on. Having excess water on the jobsite can create safety concerns. Workers can easily slip and fall if the ground is too wet or muddy. The presence of water can also lead to damaged construction equipment or it could possibly obstruct certain tasks during the project. Dewatering your jobsite not only keeps your workers and equipment safe, it ensures that you satisfy all safety and environmental regulations.
One of the most important aspects of sediment control products like dewatering bags for silt is that they help to protect our environment. Water can easily accumulate toxins, especially when it is stagnant. Dewatering bags for silt not only help to remove the water, but it also removes any toxins with the water. Water that has been contaminated with oil, grease, or chemicals should never be discharged. In this scenario, an oil/water separator will be required to finish the job.
If not done correctly, dewatering can cause erosion to occur. This is why it is so important to choose the best location for discharging the water from your jobsite. Dewatering in heavy rain is not recommended as it can become a counterproductive effort. Also in order to avoid erosion, water should never be pumped directly into slopes. Remember that certain permits may be required for dewatering in specific areas, so be sure to research this beforehand.
Requirements for Your Jobsite
When working with dewatering bags for silt or other sediment control products, there are certain requirements that you must follow in order to minimize the discharge of pollutants in stormwater from your project:
- When a body of water is located within 50 feet of the site’s earth disturbances, you must provide and maintain natural buffers and/or equivalent sediment and erosion controls.
- Direct stormwater to vegetated areas and maximize stormwater infiltration and filtering to
reduce pollutant discharges, if possible.
- Install sediment controls along any perimeter areas of the site that will receive pollutant
- Minimize sediment track-out (sediment that is carried out via the trucks and other machinery being used for the project).
- Manage stockpiles or land clearing debris piles composed, in whole or in part, of sediment and/or soil.
- Minimize dust on areas of exposed soil.
- Minimize steep slope disturbances.
- Preserve native topsoil, if possible.
- Minimize soil compaction by restricting vehicle use in certain locations.
- Protect storm drain inlets.
- Minimize erosion of stormwater conveyance channels and their embankments, outlets, adjacent streambanks, slopes, and downstream waters.
Sediment Control Products for Your Jobsite
At IWT Cargo-Guard, we offer a variety of sediment control products that provide best management practices for sediment control on your jobsite. Our EcoTube™ dewatering bags are made from high strength, permeable geotextile fabrics. The geotextiles themselves possess unique filtration and strength characteristics in order to withstand the stresses associated with the filling and placement of the tubes including abrasion, tearing, puncturing and flattening.
From dewatering bags for silt to coir logs and silt fences, we’ll make sure you are equipped with the right sediment control products for your project. Give us a call at 609-971-8810 or contact us today so that we can discuss the use of EcoTubes™ / Geotextile Tubes for your next project.
