Above ground storage tanks (ASTs) play a critical role in numerous industries, serving as essential storage solutions for materials such as water, fuel, and chemicals.
To ensure the optimal performance, safety, and durability of these tanks, businesses must carefully consider each aspect of design and planning, from tank material selection and capacity determination to foundation and containment requirements. Furthermore, adhering to industry best practices and compliance with local regulations is vital in achieving a successful above ground storage tank installation.
In this blog, we will delve into the crucial design and planning considerations for above ground storage tanks, providing valuable guidance and insights to help businesses make informed decisions throughout the design, installation, and operational phases.
Selecting the Right Tank Material
Choosing the appropriate material for your above ground storage tank is vital, as it influences factors such as durability, corrosion resistance, and compatibility with the stored substance. Commonly used materials for ASTs include:
1. Steel: Steel tanks offer high structural strength, durability, and flexibility in terms of size and shape. Coating or lining the steel may be necessary to enhance corrosion resistance and compatibility with various stored materials.
2. Fibreglass: Fibreglass tanks are lightweight and non-corrosive — an ideal choice for storing corrosive chemicals or when weight constraints apply. However, fibreglass tanks may require extra reinforcement for larger capacities.
3. Polyethylene: Polyethylene, or plastic, tanks are resistant to most chemicals, lightweight, and easy to install. While economical, they may not be as durable or capable of storing large volumes compared to steel or fibreglass counterparts.
Determining Tank Size and Capacity
Selecting the appropriate tank size and capacity involves considering factors such as anticipated storage needs, space limitations, and potential future expansions. Keep the following in mind when determining your tank dimensions:
1. Storage requirements: Analyse your business’s specific storage requirements, considering aspects like production rates, supply chain variables, and seasonal fluctuations. Adequate capacity reduces the risk of running out of stored materials, ensuring smooth operational continuity.
2. Site constraints: The size and shape of your tank should be compatible with the available site area. Factor in any clearance and access requirements, as well as height constraints on your selected location.
3. Future expansion: If your business anticipates future growth, consider sizing your tank to accommodate additional storage capacity without necessitating costly upgrades or tank replacement in the future.
Foundation and Secondary Containment Requirements
An above ground storage tank’s foundation and secondary containment system are critical components that contribute to its stability, safety, and environmental compliance. Consider the following when addressing foundation and containment requirements:
1. Tank foundation: A well-designed tank foundation provides support and stability, ensuring the even distribution of stress across the tank’s base. Options include concrete slab, crushed rock pad, or pile-supported foundations, with the choice influenced by factors such as soil conditions, tank size, and local regulations.
2. Secondary containment: Secondary containment systems prevent stored materials from reaching the environment in the event of a leak or spill. Common solutions include concrete or earthen bunds, double-walled tanks, or synthetic liner systems. The choice depends on the stored material, potential spill volume, and local regulatory requirements.
Routine Maintenance for ASTs
Regular maintenance is paramount to ensuring the optimal performance, service life, and safety of your above ground storage tank. Adopting a proactive approach to maintenance can help you identify potential issues before they escalate, avoid costly repairs, and maintain compliance with industry regulations:
1. Inspection: Schedule periodic inspections to assess your tank for structural integrity, coating or lining issues, corrosion, and any visible signs of distress, such as bulging or leaks.
2. Repairs and maintenance: Address detected issues promptly and conduct general maintenance tasks, such as paint touch-up, tightening fastenings, or servicing valves and fittings.
3. Tank cleaning: Depending on the stored substance, the tank may require regular cleaning and waste removal, ensuring optimal storage conditions and preventing buildup.
