A polypropylene tank holding about 30 tonnes of 40% aqueous caustic soda sprang a leak about halfway down the main wall. The corrosive fluid jetted out over the bund wall, causing great damage to the surrounding factory and adjacent premises.

The use of water can be important as well; however, for cooling the tank wall and adjacent Tank farms are normally safeguarded by a dyke or Underground Storage Tank Systems Containing Petroleum and Allied Petroleum.

Tanks are often surrounded by bund walls which are generally constructed either of earth or concrete. (The word “berm” is sometimes used. However, that term strictly speaking applies to the narrow walkway along the top of the bund wall.) If a tank were to suffer a catastrophic leak all of the liquid would be contained within the berm.

The term can also refer to dikes, but it is frequently used to describe liquid containment facilities that prevent leaks and spillage from tanks and pipes, though sometimes any barrier is referred to as bunding.Frequently, the liquids in these tanks and pipes are toxic, and bunding is used to prevent the liquid from causing damage (either by force or its chemistry). 1926.152(i)(2)(vii) Drainage, Dikes, and Walls for Aboveground Tanks. OSHA 1926 Construction > F Fire Protection and Prevention > 1926.152 Flammable Liquids > 1926.152(i) Tank Storage > 1926.152(i)(2) Where protection of adjoining property or waterways is accomplished by retaining the liquid around the tank by means of a dike, The volume or capacity of a tank can be found in a few easy steps. Of course, the calculator above is the easiest way to calculate tank volume, but follow along to learn how to calculate it yourself. Step One: Measure the Tank.

A large area will require a low wall in order to have sufficient volume in the containment area to hold the tank contents.
