Dewatering Box rentals from Mobile Mini Tank + Pump Solutions are passive-gravity dewatering containers available in all three of the roll-off box configurations: Roll-tarp, Metal-Lid and Vacuum. Each roll-off box is equipped with a steel-frame screen-insert which creates a French drain system within the individual containers interior. A geotextile woven or non-woven liner is installed as a filter media to allow excess liquid from the deposited slurry or sludge to leach into the annular drain space between the wall of the container and the screen insert. Drain ports installed in the bottom of the box allow for controlled discharge of the separated effluent. Upon dewatering completion, the container is picked up by a roll-off truck and taken to the desired location to be dumped and returned for reuse.
