Bunded Tanks: Worth the Bucks or Just a Gimmick?

When it comes to storing fuel safely and efficiently, choosing the right solution can make all the difference. Bunded tanks, often advertised as the safest option for fuel storage, offer extra protection, but are they truly worth the investment or just an added cost? Understanding how bunded tanks work and why they’re recommended can help you decide if they’re right for your needs. At Kenny Fuels, we support farmers, contractors, and businesses across Wexford, Wicklow, and Carlow with expert advice and quality storage solutions that help keep your fuel secure and operations compliant from day one.

Bunded Tanks: The Smart Solution for Safe Fuel Storage

A bunded tank is essentially a tank within a tank. The inner tank stores the fuel, while the outer layer—called the bund—acts as a secondary containment system. This design ensures that if the inner tank leaks or fails, the bund captures the spilt fuel, preventing contamination of the surrounding environment.

Why bunded tanks are important:

Extra protection: If the internal tank fails, the bund prevents fuel from leaking into the ground or water.
Compliant with regulations: Required in many parts of Australia when storing fuel above a certain volume, especially near sensitive areas like watercourses.
Reduced risk of fines: Helps avoid costly penalties for environmental breaches or fuel spills.
Durable and weather-resistant: Built to withstand Australian conditions, with UV-stable materials that resist rust and corrosion.
Improved fuel security: Many bunded tanks come with features like lockable lids to prevent theft.

Things to keep in mind:

Not all bunded tanks are created equal—quality tanks use materials that last and provide genuine protection.
Consider the fuel type and storage requirements to ensure you select the right tank.
Bunded tanks are more expensive than standard tanks, but the extra investment can save you from future environmental or financial issues.

When to Use a Bunded Tank

While bunded tanks are essential for some situations, they’re not always necessary for everyone. Deciding when to invest in one depends on your fuel storage needs and local regulations.

Choose a bunded tank when:

You’re storing more than 200 litres of fuel: If you’re storing larger amounts of fuel, a bunded tank is often a legal requirement.
You’re operating near sensitive areas: If you’re close to waterways, nature reserves, or other environmentally sensitive locations, bunded tanks help protect the land and comply with regulations.
You want to ensure fuel security: Bunded tanks offer extra security against leaks, theft, and environmental harm.
You’re running large-scale operations: Whether on a farm or construction site, bunded tanks provide safe, long-term storage solutions.

You may not need a bunded tank if:

You’re storing small amounts of fuel: For personal use or small machinery, a single-skin tank may suffice.
Space is extremely limited: Bunded tanks are larger and may not fit in all locations.
You’re using temporary fuel storage: If you only need short-term storage, bunded tanks might not be the best option.

The Value of a Bunded Tank: A Long-Term Investment

While bunded tanks can be more expensive upfront than standard tanks, the benefits they offer—like protection, compliance, and long-term savings—often outweigh the initial cost. A bunded tank reduces the risk of fuel spills, avoids costly clean-ups, and helps you stay compliant with environmental regulations, potentially saving you money in the long run.

Key benefits at a glance:

Minimise environmental impact: Prevents leaks from reaching the ground or water systems.
Compliant with Australian safety standards: Helps you meet local regulations and avoid fines.
Cost-effective: Reduces the need for expensive clean-up and insurance premiums.
Easy to maintain: Most bunded tanks are built to last, with minimal maintenance required.
Safer and more secure: Many bunded tanks offer extra features like lockable lids and anti-theft designs.
