What You'll Learn
Types: Underground vs. Aboveground
Fuel storage tanks are containers that keep fuel, such as diesel, safe from contamination and lengthen its life cycle. They can be made of metal or polyethylene and can be installed underground or above ground.
Underground storage tanks (USTs) are defined as tanks and connecting underground pipes used to contain regulated substances, with at least 10% of their combined volume underground. They are more expensive than aboveground tanks due to excavation work, but they offer a higher level of protection as they are sheltered, reducing the risk of explosions due to decreased pressure. USTs are made of corrosion-resistant materials such as fiberglass, which is reinforced with premium resin and glass fiber. This makes them ideal for storing corrosive ethanol-blended fuels and ultra-low sulfur diesel. Additionally, they are space-saving and can be designed to store multiple fuel types and grades in different compartments. However, one of the biggest challenges of USTs is the difficulty in detecting leaks, and they are also susceptible to freezing pipes during cold weather, which can lead to costly repairs.
Aboveground storage tanks are more accessible and come in various sizes, starting from 150 gallons up to 12,000 gallons. They are often made with double walls to meet safety regulations for storing flammable liquids. Aboveground tanks are generally more affordable and easier to maintain than USTs. However, they occupy ground space and may be more susceptible to damage from accidents or weather conditions.
Both types of storage tanks have their advantages and disadvantages, and the choice between the two depends on factors such as budget, space availability, and the specific needs of the business.

Materials and construction
Fuel storage tanks are containers that hold liquids or compressed gases. They are designed to store fuel and keep it safe from contamination. They are available in many shapes and sizes, and can be installed above or below ground. The specific construction and materials used for a fuel storage tank depend on its purpose, the substance being stored, and local rules and regulations.
The materials used in the construction of fuel storage tanks vary, with common materials being steel, stainless steel, concrete, and fiberglass.
Steel storage tanks are welded equipment that can resist external loads from soil and traffic. However, they are susceptible to corrosion and require internal and external anti-corrosion coatings. Steel storage tanks are cost-effective and can be used to store various liquids, including diesel fuel, petroleum, and chemicals.
Stainless steel tanks are resistant to UV rays, fire, and rust. They have good longevity and do not require painting.
Concrete storage tanks are widely used in the wastewater and water industries. They are strong, durable, and available in various shapes, such as circular or rectangular.
Fiberglass-reinforced polymer (FRP) tanks are resistant to both external and internal corrosion. They tend to have higher initial costs than steel tanks, but installation and maintenance costs are lower as they are lighter and do not require cathodic protection or corrosion coatings. FRP tanks are flexible and susceptible to deformation under excessive pressure, so it is important to distribute loads uniformly.
Polyethylene tanks are made of plastic and are a budget-friendly option for those who do not need a large capacity tank. They are perfect for rainwater collection.
The construction of fuel storage tanks also depends on their intended use. For example, tanks for crude oil and oil-based fuels are chosen according to the flashpoint of the material. Fixed-roof tanks are used for liquids with very high flashpoints, such as fuel oil, while floating roof tanks are used for liquids with lower flashpoints, such as jet fuel and petrol.
Additionally, the physical space available can affect the construction and installation of fuel storage tanks. Underground tanks may be preferred when there is limited space above ground, but they are more expensive due to excavation work and present challenges in spotting leaks.
