Introduction
Self bunded fuel tanks have become a preferred choice for industries, agriculture, mining, and transport businesses that require safe, efficient, and compliant fuel storage solutions. Their innovative design, which incorporates a double wall or “tank within a tank” structure, provides both primary storage and secondary containment, reducing the risk of leaks and environmental contamination.
This article will explore what self bunded fuel tanks are, their benefits, applications, compliance requirements, and maintenance best practices.
What Is a Self Bunded Fuel Tank?
A self bunded fuel tank is a fuel storage system consisting of two layers:
-
Inner Tank – Holds the fuel (diesel, petrol, biodiesel, or aviation fuel).
-
Outer Tank (Bund) – Acts as a secondary containment, designed to hold at least 110% of the inner tank’s capacity in case of a leak or rupture.
This design eliminates the need for a separate bund wall and makes the unit portable, easy to install, and compliant with environmental safety regulations.
Benefits of Self Bunded Fuel Tanks
1. Environmental Protection
The double-wall construction prevents fuel leakage from contaminating soil and waterways.
2. Cost Efficiency
They reduce fuel delivery costs by allowing bulk storage on-site, minimizing downtime for refueling.
3. Mobility
Most self bunded tanks are skid-mounted or containerized, enabling relocation when operations move.
4. Compliance
Meets Australian Standards (AS1940) and international environmental regulations for fuel storage.
5. Versatility
Can store multiple fuel types, including diesel, petrol, kerosene, and biodiesel blends.
Common Applications
Self bunded fuel tanks are used across multiple industries:
-
Construction & Mining – Powering heavy machinery and equipment.
-
Agriculture – Refueling tractors, harvesters, and irrigation pumps.
-
Transport & Logistics – Centralized fuel storage for fleet refueling.
-
Remote Sites – Supplying fuel to off-grid power generators.
-
Aviation – Storing aviation gasoline (AVGAS) and jet fuel.
Installation Considerations
Before installing a self bunded fuel tank:
-
Site Preparation – Choose a flat, stable surface away from ignition sources.
-
Regulatory Approval – Ensure compliance with local fire and environmental codes.
-
Ventilation & Access – Allow space for fuel delivery trucks and maintenance crews.
-
Spill Kits & Safety Equipment – Install appropriate fire extinguishers and emergency kits.
Maintenance and Inspection
To extend the lifespan and ensure safe operation:
-
Conduct monthly visual inspections for corrosion, leaks, and damage.
-
Test fuel quality regularly to prevent contamination.
-
Inspect hoses, pumps, and meters for wear and tear.
-
Keep records of maintenance and refueling for compliance audits.
Choosing the Right Self Bunded Fuel Tank
When selecting a tank, consider:
-
Capacity Requirements – From 1,000L to over 100,000L.
-
Fuel Type – Ensure compatibility with diesel, petrol, or biodiesel.
-
Mobility Needs – Stationary or mobile units.
-
Pump Systems – Manual or electric dispensing systems.
-
Brand Reputation – Choose a supplier with proven reliability and after-sales support.
Conclusion
Self bunded fuel tanks provide a reliable, safe, and cost-effective solution for fuel storage in various industries. Their double-wall design ensures environmental protection and regulatory compliance, while their versatility makes them suitable for a wide range of fuel types and operational settings.
By choosing the right size, ensuring proper installation, and performing regular maintenance, businesses can maximize the lifespan and performance of their self bunded fuel tanks.
