What is Bunding & Do I Need it?

Bunding, also colloquially known as a bund, is a spill containment system which forms a secondary perimeter around stored liquids. Any leaks or escapes that occur can be captured more easily with bunding. This article will focus on bunding as part of a spill management plan. Find out some commonly-asked bunding questions and answers below.

Do I need Bunding?

To determine if you need a bund for liquids stored in your facility, you should consider:

  1. What type of liquid is being stored? What are the potential environmental impacts? For example, if you have liquids that are stored near bodies of water, it is essential for these to be bunded.
  2. How much liquid? Bunds can prevent catastrophic spills from large containers and reduce clean up efforts.
  3. Is your facility equipped for your largest potential spill? Spill kits combined with adequate bunding can ensure peace of mind and EPA compliance.
  4. Duration – How long will liquids be stored? Liquid storage containers can fail at any time and this risk increases due to age and the environments in which they are stored.

Bunding for Liquid Drums

Stratex Drum and IBC Bunding
Hard cover and IBC bunding provides safe liquid storage outdoors.

A 44 gallon drum is 205 litres; no small amount by any means. Some form of bunding is essential for the safe storage and transport of liquid storage drums. Bunded spill pallets can provide low profile leak and spill proof storage, preventing costly and environmentally damaging spills. These pallets are forklift compatible and available in durable polyethylene and steel.

What is an IBC Bund?

IBC stands for Intermediate Bulk Container, used to store liquids, semi-solids and solids. The average IBC capacity is 1000 litres, potentially resulting in huge damage if a leak were to occur. Storing an IBC on a bunded pallet is good practice to reduce the risk of spills. When choosing an IBC bund, it’s important to consider how much fluid will be stored. Bunded storage should hold at least 110% of the maximum capacity of your largest tank or drum.

For IBC bunds kept outdoors, storage covers are available. These can be fitted over IBCs for protection from the elements, and are available to suit a variety of storage sizes. For bunds stored outdoors, we recommend fitting drain bungs to allow the escape of rainwater.

What is a Bund Wall?

Some fluid storage areas feature permanent bund walls constructed around them. These are usually made from concrete and are designed to contain large amounts of liquid from an emergency leak or spill. Drive over (or floor bunding) can also be used as a bund wall to contain smaller volumes of liquid.
