Frequently Asked Questions
How long do bunded tanks last?
A Harlequin oil tank comes with a 10-year warranty, as standard – but when installed and maintained properly, it can last much longer.
Although our bunded oil tanks are made from MDPE, a material that offers excellent chemical and impact resistance, it’s advisable to check for signs of damage and degradation to eliminate risk to the environment. After all, oil that leaks into rivers, streams, lakes and ponds could poison fish and wildlife!
If you need to replace your bunded tanks, be sure to check out the fantastic range we supply from Harlequin.
How does a bunded tank compare with a single-skin oil tank?
A bunded tank has a secondary containment area to prevent spillages.
If the internal tank fails or splits, the oil will be caught by the secondary bund, rather than leaking into the surrounding areas and contaminating the environment.
Exactly as its name implies, a single-skin tank only has one skin that fuel is held within. There is no failsafe.
Boasting a simple construction, single-skin fuel tanks are generally cheaper than bunded oil tanks and are easier to install and maintain.
Is a Harlequin oil tank worth it?
Call us biased, but here at Cotterill Civils, we believe that bunded oil tanks from Harlequin are some of the best you can buy!
These are fully bunded and meet the current regulatory requirements for the storage of oil and fuel.
If the internal tank were to leak, you can trust that the excess fuel would collect in the outer tank – protecting the surrounding environment from pollution.
Whether you require a bunded tank for smaller storage uses or larger purposes, you’re sure to find something suitable within our online collection. After all, we stock them in a choice of sizes – ranging from 350 litres right the way up to 54,000 litres.
Another great reason to consider a Harlequin oil tank is that, as a result of being made from MDPE, they are non-corrosive. And available for a highly competitive price, you can benefit from top-quality products without breaking the bank.
Why are bunded tanks needed?
Bunded oil tanks are a legal requirement for new domestic, commercial and agricultural tank installations.
Unlike older single skin tanks without a bund, these offer more environmental protection – making them the safest way to store fuel – and they usually have a longer warranty, providing additional peace of mind.
Often, insurance companies won’t cover a policyholder for an oil spill. But thanks to their second containment, bunded tanks can prevent leaks and spillages – saving you from being handed a costly fine.
