Depending on the size of the dewatering job and the pump rate into the bag, customers will typically choose between either a dewatering bag or dewatering tube.

Dewatering filter bags, also known as the silt bags or sediment filter bags, are smaller dewatering options made from nonwoven materials. A geotextile bag is available in sizes ranging from 6' x 6' to 15' x 25.'

By contrast, dewatering tubes are built in sizes up to 250' in length and are made from a heavier woven geotextile fabric.
