Soil erosion causes silt, sand, and dirt to collect in streams and surrounding properties. This can be damaging to landscapes and construction. To address soil erosion in these situations, dewatering bags are an economical and practical option. Dewatering bags remove sediment and silt from a site by filtering water through geotextile material. There various sizes and capacities of bags to suit your needs.
Dewatering Bag Overview
Dewatering bags are designed to filter sludge, sediment, and silt from a work site, construction site, or another field of operation. Bags are placed strategically on a site, and water is directed into them. As the water moves through the geotextile fabric of the dewatering bag, sediment is captured inside for later disposal.
There are many benefits to dewatering bags. They remove water from silt and soil without a container, reduce waste volume, use internal pressure for dewatering, remove contaminants from water, can be used in hard-to-access locations, and are relatively easy to use. Each bag’s structural integrity and flow depends on the soil type and area.
Bags are available in different sizes and with various filter properties. Fabric ratings determine how quickly and thoroughly water can filter out, which allows you to estimate pumping rates. The capacity of dewatering bags is based on soil composition, site conditions, and use. You will only know what a dewatering bag is capable of on your site once it’s been field-tested.
Discharge Hose
Each bag is designed to handle a certain size discharge hose. This is how water is guided from the point of origin to the dewatering bag. Most bags have holes designed for a specific-size tube. Alternatively, you can make a small incision in the fabric to allow a hose to be fed through. Once placed, tie the fabric to the hose using wire, ties, ropes, or other materials to seal the entrance.
Bag Placement
Dewatering bags are rugged but not indestructible. To get the best results from dewatering bags, it’s important to place them appropriately. Be sure to look for sharp rocks or edges before placing the bag to avoid rupturing the fabric. They are not recommended for use on steep slopes, as the bags can roll.
It’s also a good idea to find a porous surface on which to lay the bag, as this will allow the filtered water to soak quickly into the ground. It’s also important to direct water runoff or place the bag somewhere that won’t result in further soil erosion.
Complying With Regulations
Dewatering bags can also help your job site or location stay in compliance with both local and federal stormwater regulations. Some states and cities have regulations that differ from national guidelines, so it’s important to research these requirements before installing dewatering bags.
When it comes to preventing and addressing soil erosion, there are a lot of products on the market. One of the easiest and most economical solutions is dewatering bags. Try dewatering bags to address soil erosion on your property, construction site, dredging area, and more.
