Leak Detection Compliance for Fuel Depots: ATG vs SIRA Explained
18 November 2025
Ensure fuel depot compliance in Australia with Future Fuels. Learn the differences between ATG and SIRA systems to protect operations and reduce risks.
Leak detection compliance is critical for fuel depots to safeguard the environment, uphold safety, and meet strict regulatory obligations. Implementing dependable systems helps identify even the smallest leaks before they result in costly damage or fines. Among the most widely used solutions are automatic tank gauging (ATG) and statistical inventory reconciliation analysis (SIRA), both designed to support effective compliance and operational efficiency.
Understanding Automatic Tank Gauging (ATG) Systems
Automatic tank gauging is a continuous monitoring system that uses sensors installed inside underground and above-ground storage tanks. These sensors measure fuel volume, temperature, and water levels in real time.
Key advantages of ATG include:
• Provides instant alerts for unusual activity or sudden fuel loss.
• Delivers accurate, real-time data on fuel volume, temperature, and water levels.
• Simplifies inventory tracking and compliance reporting with precise measurements.
• Reduces manual inspections through automated monitoring and record-keeping.
• Enables rapid leak response, improving safety and environmental protection.
ATG is ideal for sites requiring real-time monitoring and rapid response to potential leaks. However, installation can be costly, and routine calibration is needed to maintain accuracy.
How Statistical Inventory Reconciliation Analysis (SIRA) Works
Statistical inventory reconciliation analysis (SIRA) relies on a data-driven process that examines delivery records, sales figures, and tank measurements over time. Unlike automatic tank gauging (ATG), it operates without physical sensors inside the tanks. Instead, specialised software analyses patterns and discrepancies to identify potential leaks.
SIRA offers several advantages, including lower installation costs due to the absence of in-tank hardware and seamless integration with existing reporting systems. It is widely accepted for leak detection compliance across many regulatory jurisdictions. However, while highly accurate, SIRA performs best in stable operations and may not detect sudden leaks as quickly as ATG.
Choosing the Right System for Your Fuel Depot
Selecting between ATG and SIRA depends on operational priorities, budget, and compliance obligations. Consider the following factors:
• Site size and complexity – ATG is ideal for large depots with multiple tanks, while SIRA suits smaller sites with simpler operations.
• Budget constraints – SIRA offers a lower-cost option with minimal setup, whereas ATG requires a higher investment for equipment and installation.
• Regulatory requirements – Certain regions require ATG for real-time detection, while others accept SIRA for compliance reporting.
• Response time needs – ATG delivers immediate alerts for rapid action, while SIRA focuses on trend analysis over time.
Maintaining Compliance Through Best Practices
Proactive management is essential for maintaining compliance and minimising environmental risks at fuel depots. Regular calibration, equipment checks, and accurate record-keeping help ensure systems operate reliably.
Staff should be trained in leak detection response procedures and updated on evolving regulations. Periodic reviews of compliance guidelines keep operations aligned with industry standards and legal requirements.
