Self Bunded Fuel Tanks

What is a self bunded fuel tank?

A self-bunded fuel tank (also known as a double-walled fuel tank) is a storage tank specifically designed to safely hold fuels, oils, or other hazardous liquids. The term "self-bunded" means it has a built-in secondary containment layer — essentially a tank within a tank.
Key Features:
  • Double wall structure: The inner tank holds the fuel, while the outer tank (bund) serves as a safety barrier to contain spills or leaks.
  • Environmental protection: If the inner tank fails, the outer shell prevents fuel from contaminating the surrounding area.
  • Compliance: These tanks often meet environmental and safety regulations for above-ground fuel storage.
  • Portability: Many self-bunded tanks are modular and can be transported to remote or temporary worksites.
  • Capacity: They come in a wide range of sizes — from a few hundred litres to tens of thousands of litres.
Common Uses:

  • Refuelling for construction or mining equipment

  • Fuel storage for farms or transport fleets

  • Diesel or petrol storage at remote locations

  • Emergency fuel reserves

Do fuel tanks need to be bunded?

Yes, fuel tanks often need to be bunded — especially in commercial, industrial, or environmentally sensitive settings — to comply with safety and environmental regulations.


When Is Bunding Required?

Legally Required If:
  • You’re storing large volumes of fuel (commonly over 1,000 litres, though this may vary by region)
  • The tank is located in areas where spills could harm the environment (e.g., near waterways, storm drains, or sensitive land)
  • Your local regulations mandate bunding (e.g., Australian Standards AS1940 or the UK’s Environment Agency rules)
  • Common Situations That Require Bunds:
  • Fuel storage on construction and mining sites
  • Farms or transport depots storing diesel or petrol
  • Above-ground storage tanks at businesses
  • Anywhere fuel leakage could pose a fire, explosion, or pollution risk
