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

What Are the Different Types of Diesel Tanks?

There are several types of diesel storage tanks, each designed to suit different applications, environments, and regulatory needs:

- Self-Bunded Tanks: These double-walled tanks have built-in secondary containment to prevent leaks and spills. Ideal for above-ground use on farms, construction sites, and industrial areas. They’re compliant with most Australian safety standards.
- Single-Skinned Tanks: These tanks consist of a single wall and require separate bunding or containment measures. Typically used in less regulated environments or within containment areas.
- Portable Diesel Tanks: Small, mobile tanks often mounted on utes, trailers, or trolleys. Suitable for onsite refuelling of vehicles and machinery.
- Underground Diesel Tanks: Used in commercial fuel stations or large-scale industrial setups. They help save space and protect fuel from temperature fluctuations but require extensive regulatory compliance.
- Poly Diesel Tanks: Made from high-density polyethylene, these tanks are corrosion-resistant and lightweight, suitable for portable or stationary use.
- Transport-Approved Tanks (IBC Diesel Tanks): Intermediate Bulk Containers (IBCs) designed for safe and legal transport of diesel under Australian Dangerous Goods (ADG) Code regulations.
- How Do I Maintain a Diesel Storage Tank?

Proper diesel tank maintenance ensures fuel quality, system longevity, and safety. Here’s how to maintain your diesel tank effectively:

- Regular Inspections: Check for corrosion, leaks, cracks, and worn fittings—especially around pumps, valves, and seals.
- Water Removal: Diesel can absorb moisture, leading to microbial growth and fuel contamination. Drain water from the bottom of the tank regularly.
- Filter Changes: Replace fuel filters on dispensers and pumps as part of routine service.
- Tank Cleaning: Clean the inside of the tank periodically to remove sludge, sediment, and microbial build-up (diesel bug).
- Protect From UV and Heat: For poly and above-ground tanks, use covers or shelters to reduce sun exposure and temperature variations.
- Fuel Testing: Periodically test stored diesel for water content, microbial activity, and degradation—especially for tanks storing fuel long-term.

Preventative maintenance not only extends tank life but also protects your equipment from contaminated fuel.

What Are the Safety Regulations for Diesel Tanks in Australia?

Diesel tank safety regulations in Australia are governed by national standards and state-based environmental and workplace safety laws. Key requirements include:

- AS 1940 Compliance: Tanks must comply with AS 1940: The Storage and Handling of Flammable and Combustible Liquids, which sets guidelines for tank construction, placement, bunding, and fire safety.
- Bund Requirements: Above-ground tanks must have secondary containment (bunds) capable of holding 110% of the largest tank’s capacity to prevent environmental contamination.
- Ventilation and Signage: Adequate venting, emergency signage, and spill kits are required onsite.
- Environmental Regulations: Operators must comply with EPA and local council requirements regarding site planning, drainage protection, and spill control.
- Transport Compliance (ADG Code): Portable and mobile tanks must meet the Australian Dangerous Goods Code requirements if transported.
- Workplace Health & Safety (WHS): Employers must provide training, maintain safety data sheets (SDS), and manage risks under WHS regulations.

Failure to comply can lead to fines, environmental damage, or injury. Always consult your local authority or a certified installer for site-specific compliance.
