Bunded tanks are utilized to contain hazardous toxic substances and prevent them from overflowing. Bunded tanks are different from other oil storage tanks because they have a secondary containment tank. The outside skin, also called the bund wall, is sturdy enough to ensure that the liquid contained does not cause any damage to the environment. This feature helps prevent any oil from spilling out onto the ground. If there is any leakage from the main storage tank, it will still be contained safely within the exterior wall. These tanks are more robust than any other type of containers.
Is a bunded tank right for you?
Bunded tanks are useful for most commercial and industrial sites. They are also required in certain circumstances such as if your containers at your home or commercial premises have the capacity to store over 3,500 liters, it will need to be bunded. A bunded tank is also required if the container needs to be in a location with a risk of an oil spillage. Containers near a public water source, lake, river or stream are extremely dangerous.
Other features of a bunded tank
The features of a bunded tank vary according to its size and model. Bunded tanks have other standard safety features aside from its bunded walls that prevent spillage. A bunded tank includes a tank gauge, which indicates how much fuel is left in the tank. With a tank gauge, you will know whether it’s time to refuel.
Another feature is its lockable fill point that prevents any fuel theft. You’ll also find a secure fuel inspection hatch, which is designed for fuel access and to clean the tank. If there is a sudden decrease in fuel either due to leakage or oil theft, you will know by its alarm system. Moreover, putting too much oil in the tank is prevented by an overfill protection device.
What is the capacity of the bunding?
The outer part of the tank is designed to hold more than the capacity of the inner tank, to ensure that nothing spills out in the case of leakage. The outer section also stores the pipes and vents of the tank. It can hold at least 110% of the fuel capacity of the inner tank. Some can hold more than that amount, depending on the make and model of the tank.
A bunded fuel tank is a great way to store any hazardous substances because of its strong protective layer. With its ability to prevent damage to the environment due to leakage, it is the most environmental-friendly option. The tank’s double layering also makes it impossible to steal fuel from the inner section of the tank, thus preventing fuel theft. Moreover, the outer wall provides protection to the inner tank wall from any impact damage.
