When it comes to storing diesel fuel and chemicals safely and efficiently in Australia, selecting between single-walled and double-walled (self-bunded) tanks is a decision of paramount importance. This choice not only affects operational efficiency and cost-effectiveness but also has significant implications for environmental safety and regulatory compliance.
Australia’s stringent environmental regulations, such as AS1940:2017, mandate specific requirements for the storage of flammable and combustible liquids. Non-compliance can lead to severe penalties and environmental hazards. Single-walled tanks, while initially more affordable, often necessitate additional secondary containment measures, like bunding, to meet these standards. In contrast, double-walled tanks offer integrated protection, reducing the risk of leaks and simplifying compliance.
Moreover, the potential environmental impact of fuel or chemical leaks—ranging from soil contamination to groundwater pollution—underscores the need for robust storage solutions. Therefore, understanding the differences between these tank types is crucial for businesses aiming to operate responsibly and sustainably.
Understanding Single-Walled Chemical Storage Tanks
What Are Single-Walled Tanks?
Single-walled tanks are constructed with a single layer of material and are designed to store substances like diesel, AdBlue™, and various chemicals. While they are cost-effective and suitable for certain applications, they require additional safety measures to prevent environmental contamination.
Advantages of Single-Walled Tanks
- Cost-Effective: Lower initial investment compared to double-walled tanks.
- Lightweight and Easy to Install: Their design allows for straightforward installation, especially in areas with limited space.
- Suitable for Controlled Environments: Ideal for indoor use or locations where external containment systems are already in place.
Considerations for a Single-Walled Chemical Storage Tank
In Australia, storing hazardous substances like diesel requires adherence to strict regulations. According to AS1940:2017, single-walled tanks must be used in conjunction with secondary containment systems, such as bunds, to prevent leaks and spills from contaminating the environment. This means additional infrastructure and maintenance, potentially offsetting the initial cost savings.
Exploring Double-Walled (Self-Bunded) Chemical Storage Tanks
What Are Double-Walled Tanks?
Double-walled tanks, also known as self-bunded tanks, consist of an inner tank enclosed within an outer tank. The outer tank acts as a built-in bund, capturing any leaks or spills from the inner tank, thus providing an added layer of environmental protection.
Advantages of Double-Walled Tanks
- Enhanced Safety: The integrated bunding system reduces the risk of environmental contamination.
- Regulatory Compliance: Often meets or exceeds Australian standards without the need for additional containment structures.
- Cost Savings Over Time: Eliminates the need for constructing separate bunds, reducing installation and maintenance costs.
- Versatility: Suitable for a wide range of applications, including remote locations and areas with strict environmental regulations.
Considerations for a Double-Walled Chemical Storage Tank
While double-walled tanks have a higher upfront cost, the long-term savings from reduced infrastructure and maintenance can make them a more economical choice over time.
The Tank Factory’s Storage Solutions
The Tank Factory offers a comprehensive range of storage tanks tailored to meet various industrial and commercial needs:
Single-Skin Diesel, AdBlue™, and Chemical Storage Tanks
Ideal for applications where external bunding is already in place or managed separately. These tanks are available in capacities ranging from 1,000 to 20,000 litres, providing flexibility for different operational requirements.
SmartBund™ Self-Bunded Tanks
The SmartBund™ range features an extra heavy-duty inner tank encased within an integrated outer bund. This design eliminates the need for external concrete bunds, reducing installation costs and space requirements. Capacities range from 700 to 20,000 litres, accommodating diverse storage needs.
Regulatory Compliance in Australia
In Australia, the storage and handling of flammable and combustible liquids are governed by AS1940:2017. This standard outlines the requirements for safe storage, including the need for secondary containment systems to prevent environmental contamination.
Double-walled tanks, like The Tank Factory’s SmartBund™ range, often meet these requirements without additional infrastructure, simplifying compliance and reducing costs.
Choosing the Right Tank for Your Needs
When selecting between single-walled and double-walled tanks, consider the following factors:
- Regulatory Requirements: Understand the specific regulations applicable to your industry and location.
- Environmental Impact: Assess the potential environmental risks and the importance of containment systems.
- Budget Constraints: Evaluate the initial investment versus long-term savings.
- Operational Needs: Consider the volume of storage required and the nature of the substances being stored.
