Bunded Oil Tanks

Modern designs to fit all applications

The Harlequin range of plastic 'Bunded Oil Tanks' offers an ideal solution for the storage of heating oil in a wide range of domestic and commercial settings. These oil tanks are designed to provide safe, efficient, and reliable oil storage.

A bunded heating oil tank simply consists of a tank within a tank. Heating oil is stored in the inner tank and the outer tank acts as a fail safe so that in the event of a spillage, excess fuel will collect in the outer tank. The bunded design helps avert pollution incidents should there be a leak and avoid the hassle of costly environmental clean-up operations. Bunded oil tanks have been proven to significantly reduce the risk of pollution. They are a requirement for most domestic and commercial premises in the United Kingdom and Ireland.

Frequently Asked Questions

What Is a Bunded Oil Tank?

A bunded oil tank is a type of storage tank used for holding oil, commonly heating oil for domestic or commercial use. The term “bunded” refers to its design, which includes two tanks, essentially one tank inside another.

The space between the inner tank and outer tank, known as the bund, is designed to contain any leakage or spillage from the inner tank. This is a crucial safety feature as it prevents oil from escaping into the surrounding environment.

What Are The Bunded Oil Tank Regulations In The UK?

In the UK, the use of bunded oil tanks is mandatory under specific circumstances, they are primarily driven by the need to prevent oil pollution. Domestic tanks with a capacity over 2,500 litres must be bunded; bunding is also necessary if the tank is situated near water sources or areas prone to environmental contamination.

For commercial and agricultural installations, where larger volumes of oil are stored, bunded tanks are typically required due to the increased risk. New installations and tank replacements must comply with these regulations, often necessitating the adoption of oil bunded tanks.

How Do I Know If My Oil Tank Is Bunded?

To determine if your oil tank is bunded, look for a double-layered construction consisting of an inner and an outer tank. This design is distinct from single-skinned tanks, which only have one layer. If you see a secondary containment around the primary tank, or if there’s a noticeable gap between two walls of the tank, it’s likely a bunded tank.

Additionally, bunded tanks often have a capacity label or a manufacturer’s tag indicating their bunded nature. If you’re still unsure, consulting a professional or referring to the tank’s documentation can provide confirmation.
