Dewatering Containers are water tight boxes that have an internal porous structure supporting a filter media, along with drain ports to allow the filtered water to escape. The most common type of dewatering container is based on a roll-off box design, although any type of container that is water tight can be made into a dewatering box. This includes containers that are commonly referred to as self-dumping hoppers and front loaders.
Other types of containers being used in the waste water industry, such as side and rear loaders and lugger boxes can also be manufactured as dewatering boxes. There are basically two varieties of these dewatering containers: those that have permanent filters and those that use disposable filters. Within the permanent filter category there are multiple configurations of filter orientation, materials of construction, and filter porosity. The most common type of disposable filter is a needle punched polypropylene geotextile.
