Large Dewatering Bags for Silt

Dewatering Bag Specifications

Dewatering silt bags are widely known as effective BMPs for removing sediment or sludge from construction sites and processing ponds. Pump contaminated water directly into large dewatering bags and gravity does the rest, with the clean water flowing out of the silt bag leaving the sediment behind. Easy to install and use, these sediment bags are perfect for storm water runoff, dewatering, or filtration. Silt bags for dewatering make sure the silt stays in one place for quick disposal.

Each silt bag can hold between 1 and 15 cubic yards of material, depending on sizing. Most options range from 4 by 6 feet to 15 by 25 feet. They are typically placed on the ground in the dewatering area but can also be kept on trucks for easy transportation. Custom sludge dewatering bags are also available. However, for particularly large dewatering projects, dewatering tubes are recommended.

8 oz. Sediment Filter Bags

Our lightest silt bag uses an 8 ounce nonwoven geotextile fabric. They are best suited for situations and applications with a thinner sediment/water mix. You can use large dewatering bags to dredge the water hazards at public golf courses and other dredging locations. During a small construction project, you can use silt bags to filter and control polluted runoff to prevent unwanted materials from leaving your job site. See: Dewatering Bags Flyer (pdf), you can download and fill out our short dewatering questionnaire and tell us more about your project. This will help us tailor our services to your specific needs and offer you the best options.

10 oz. Sediment Filter Bags

If you are looking to remove sludge with particularly thick mixtures, the 10 ounce silt filtration bag is our heavy duty option. These dewatering sediment bags work well for cities that use stormwater detention ponds as part of their Stormwater Pollution Plan or for facilities that use processing ponds. Sludge and sediment build up can become heavy in stormwater retention ponds, requiring a more substantial solution. With silt bags and large dewatering bags you can dredge sludge from canals and other small boat waterways. Learn more about our solutions for stormwater runoff.

Neil B. said: Thank you for your note and follow up. The installation went very well and not only repaired the shore line, but also seems to be averting further erosion as we hoped. I am very happy with the result and just shared my experience last month with all who attended our Water Association annual meeting. You may be hearing from some of my neighbors. Thanks again!

Customer Coir Log Testimonial

I have been very pleased with the customer service from One Clarion. I received a power washer that was severely damaged during shipment. I called to let Arian in your Customer Service Dept. know. She was very quick to contact the carrier, who in turn picked up the damaged item the same day. Within a week’s time, I received my replacement power washer! I am very pleased to say, the customer service from One Clarion, far exceeded my expectations! Thank you!

Sincerely,
Mel B.
