Remove and Dewater Material From A Pond
Question: Need to dewater material from a pond and remove an estimated 45 short tons of material from a pond. The 45 short tons is the estimated dry weight of the material. This is a large project where we are building two new ponds but need to rehabilitate three old ponds. We are dredging hydraulically and looking to level some ground and lay poly sheets to a collection point. I noticed in a picture that we might be able to dredge in one pond and put the dewatering geotextile bag in another pond. Is this correct? Does the second pond have to be dry? How does the roll off dumper container work with the bags?
Answer: Thank you for contacting us. For the size of your project and the amount of material you are looking to contain, the best option may be one of our Dewatering Geotextile Tubes. These dewatering products are created very similar to the dewatering bag, but are significantly larger in size. This allows large jobs to dewater and contain their materials.
These dewatering tubes are a favorite for different locations looking contain their materials. Some applications where these products have been used include the following:
- Large Lagoon Dewatering Projects
- Waste Water Treatment Plants
- Sludge Dewatering Projects
- Large Pond Dewatering
- Dewatering in Aquaculture Facilities
- Pulp and Paper Mill Dewatering
These tubes have been made in lengths as long as 200 feet and with circumferences anywhere from 15 to 90 feet. Different sizes may work better depending on the amount of available space you have and the size of the particles you are looking to contain.
Depending on your conditions, you may be able to dredge one pond and place the dewatering bag in the other pond. Typically, though, you should not place the bag into pond full of water. If you are using poly sheets, you may be able to place the tubes on these sheets along the side of the pond to allow water to flow into the second pond.
Roll-off dumper containers could be used. Sometimes these containers are used to ease the handling side of things but if the material takes a long time to dry it can become a problem as the roll offs need to be rented for longer.
Each job is a little different. Our product specialists could advise you and assist finding the right product for your application. Learn more about Dewatering Bag options.
