Dewatering Bag for Construction Site

sediment filter bag

Question: Hello. I am looking for a dewatering sediment filter bag that I can use to help filterout some of the materials on my site. Do you have these types of bags?

Answer: Thank you for contacting us! We do offer several different sized Dewatering Bags that I can be used to filter out materials such as soils, sediment, and several other site requirements.These bags have often been used to filter out small lakes and ponds,allowing only clean water to leave or be removed from the site.


The dewatering bag is created from a non woven geotextile material. This needle-punched fabric offers high permittivity, while still remaining secure enough to retain fine soils. Bags come in either an eight or ten ounce (8 or 10 oz) fabric depending on the strength needed for filtering and sediment removal on your site.

As a filtering material, bags contain a different filtering rate depending on the size fabric that is being used. The 8 oz. fabric typically offers a filtering of 80 gpm per square foot. The 10 oz. fabric offers 60 gpm per square foot.

Choosing a Dewatering Bag

Choosing the right Dewatering Bag for your location can depend on several different factors including:

  • Volume of Water being Pumpeddewatering bag
  • Type of Sediment you need Retain
  • How much Sediment needs to be Retained
  • Permittivity of your Bag

These sediment filter bags are typically placed in level locations so prevent the bag from sliding or moving during a filtering process. Depending on the size of your bag, they may also be placed in containment units such as a 20 foot drop box, a dump truck or other similar items. If placed on a ground location, runoff from these tanks should be guided to the nearest inlet.

When using these bags, dewatering units are typically hooked up to an available discharge hose. Each bag can typically handle a discharge hose that measures either two, three or four inches.
