• • 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?

• • 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.

• • 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.

Self-Bunded Diesel Tank

What maintenance is required for self-bunded diesel tanks?

Regular maintenance of self-bunded diesel tanks is essential to ensure fuel quality, prolong equipment life, and meet environmental compliance standards. Key maintenance practices include:

• Routine inspections: Visually check the tank’s inner and outer walls for corrosion, leaks, or structural damage.
• Check fuel levels and usage: Use dipsticks, gauges, or monitoring systems to ensure accurate readings and detect anomalies.
• Remove water and sediment: Diesel can attract water and microbial growth. Drain the water trap periodically and clean out sludge buildup.
• Service pumps and filters: Clean or replace fuel filters regularly to maintain flow and prevent contamination.
• Inspect hoses, fittings, and valves: Look for wear, cracks, or loose connections to prevent fuel leaks or pressure issues.
• Test bund integrity: Ensure the outer bund can contain any leaks from the inner tank and remains structurally sound.
• Document maintenance: Maintain accurate records of inspections, servicing, and repairs for audit and compliance purposes.

Following a scheduled maintenance routine reduces costly downtime, extends equipment lifespan, and maintains diesel purity—especially under harsh Australian conditions.

How do I ensure compliance with safety standards?

To comply with Australian safety and environmental regulations for self-bunded diesel tanks, follow these key steps:

1. Adhere to AS 1940 standards: Ensure that tank design, installation, and maintenance meet the AS 1940 – Storage and Handling of Flammable and Combustible Liquids standard.

2. Site planning approval: Obtain necessary approvals from local councils or environmental authorities before installation.

3. Secondary containment: Ensure the bund can contain at least 110% of the tank's capacity or meets relevant regulations.

4. Proper signage and labelling: Use compliant hazard and fuel identification labels as per WHS requirements.

5. Spill response preparedness: Keep spill kits, fire extinguishers, and safety data sheets (SDS) on site.

6. Scheduled inspections and documentation: Maintain logs of inspections, servicing, and any repairs.

7. Trained personnel: Ensure all staff handling diesel are trained in proper handling and emergency procedures.

These practices help maintain regulatory compliance, improve safety, and minimise business liability.

Can self-bunded diesel tanks be relocated?

Yes, self-bunded diesel tanks are designed for relocation, making them an efficient and cost-effective choice for dynamic job sites. Their integrated double-wall design removes the need for external bunding, simplifying transport and setup.

Key considerations when relocating a tank:

• Drain fuel if required: Some sites or transport companies may require partial or full emptying for safe transport.
• Use designated lifting points: Most tanks feature engineered lifting lugs or forklift pockets to ensure safe handling.
• Conduct reinspections post-move: After relocation, inspect for transport-related damage and verify the condition of pumps, fittings, and the bund.
• Update site compliance: Ensure the new location meets all local environmental and safety requirements.

Self-bunded tanks are ideal for industries like construction, agriculture, and mining—where on-site fuel flexibility is crucial without compromising safety or compliance.
