Why E-Tank?

Whether a sludge box is actually water tight depends upon the condition of the gasket and proper alignment of the gate. E-Tank performs a complete maintenance process each time a roll-off box is returned after a rental.

Liners make cleanup easy

E-Tank can supply an optional liner that will contain the material until the box is dumped at the disposal site. Ask your sales representative for more information.
