Bunded Area
Bunded Area
(OP)
What capacity should a bunded area containing a number of different tanks be able to store? I have heard 110% of the capacity of the largest tank but cannot find it.
Please advise and also state where in which standard I can find this.
Thanks

Most storage tanks located in the USA use the 110% criteria for the bund (containment) design. It is incorporated into State statutes and laws.
Some US states also add a "rainfall factor" of about 6 inches to the wall height.
It is also important to consider the bund material (concrete, earth with a memebrane and clay are often used) as well as access to the contained area.
A bund containing a number of tanks of different volumes needs to be designed only for the failure of the largest one.

US EPA requires 110% (enforcable) or largest tank volume + 25 years,24 hours storm event (non-enforcable)
