Abstract
A secondary containment reservoir device having a bottom and side walls forming a reservoir, and communicating with the reservoir an expandable retention bladder which automatically expands to receive liquid from the reservoir, allowing the total capacity of the device to greatly exceed the capacity of the reservoir alone. The device can be adapted to receive or support any type of primary liquid container above the reservoir, including drums, barrels, tanks, IBC's, tanker vehicles, tanker trailers or railroad tankers. In one embodiment, the reservoir is formed within a pallet having a support deck to receive drums or barrels of liquid. A single bladder or multiple bladders may be used, and the bladders may be mounted internally or externally.
