Defining Self-Bunded Tanks

Self-Bunded Tanks

Self-bunded tanks should become your storage solution of choice if you own an enterprise that is involved in the trading of liquid fuel or if your business does have a constant requirement for such high-value liquid, you will realize how important it is to have a ready access to this kind of reliable and highly dependable storage solution.   

A bunded storage and containment system is a tank within another tank. It is primarily designed to safely and securely contain your high-value liquid via its double steel walls which allows for effective storage and containment of diesel, fuel and other liquids of high-value or interest. 

Sometimes these tanks are referred to as double-walled tanks. In between the inner and outer tank, they have a space gap with a capacity of 110% of the inner tank’s. The purpose of such a design is to reduce the chances of losing the high-value liquid through leaks or spills. By virtue of this attribute, environmental contamination will be unlikely to happen. 

Bunded Tank Standards

Owing to the stringent industry regulations and Australian environmental laws, the utilization of bunded containment and tank systems has immediately become a necessity for many business entities that require immediate access to their fuel or any other liquid of high value for them to be stored on site. 

The reliability of self-bunded tanks, as well as its strength and durability, has proven itself as one effective and safe storage system.  


By its sheer design,  bunded fuel tanks are built tough, durable, and long-lasting.  It comes with double steel walls that significantly helps in keeping spillage and leaks of the high-value liquid you’d have it contained. 

Should there appear a leak on the first wall, the second wall is sure to keep it from spilling through, otherwise it would run the risk of contaminating its immediate surroundings. 

Although it is very unlikely that the first wall (sometimes referred to as bund wall, so don’t confuse yourself with that) will get damaged and cause your liquid to spill over since the material is given a very robust structural design. 

Truly, we can safely say that the strength and durability of self-bunded storage tanks is something you can count and rely on. 


If you are not aware yet, bunded storage systems can hold and contain large amounts of your high-value liquids. Their storage capacity would typically range from 1,000 liters to 150,000 liters. 

If your enterprise requires that you have an amount of fuel within that range or you need to have a kind of petrochemical product stored on-site, it will eliminate the need for your staff to leave your manufacturing or work facility just to have their machinery or vehicle refilled with fuel. 

Storing fuel in large amounts of it in your site will save for you and your staff valuable time and money in traveling to and from refueling stations. And the best part of it is that setup is easy as 1-2-3.
