What You'll Learn
Above-ground vs underground fuel tanks
Fuel storage tanks are containers designed to store various types of fuel, including gasoline, diesel, jet fuel, and biofuels, for extended periods. When choosing a fuel storage tank, there are several factors to consider, including available space, budget, regulations, secondary containment, material, and serviceability.
Above-ground fuel storage tanks are large containers typically placed outdoors or within dedicated containment areas. They are constructed from materials such as steel, fiberglass, or reinforced concrete, depending on the intended use, environmental conditions, and regulatory requirements. Above-ground tanks are easy to access for maintenance and inspection, making them straightforward to operate and maintain. They can also be installed quickly and easily, with only minor excavation needed for tank footings and piping. However, they require more space and are more susceptible to fire and explosion risks due to their exposure to pressure and temperature fluctuations and external elements.
Underground fuel storage tanks, on the other hand, are buried under the ground, minimizing their surface footprint. This makes them ideal for locations where space is limited or where above-ground structures are undesirable, such as in urban or environmentally sensitive areas. Underground tanks provide natural insulation and protection from extreme temperatures, weather events, and potential vandalism, reducing the risk of corrosion and extending the lifespan of the tank. They also offer flexibility in placement within a property. However, underground tanks require more specialized installation procedures, and repairs can be more costly when components need to be excavated. Additionally, detecting leaks in underground tanks can be challenging, potentially leading to significant contamination before the issue is identified.
The cost of a fuel storage tank includes both the cost of the tank itself and installation. Above-ground tanks generally have lower initial costs and are less expensive to install, while underground tanks may require additional planning and logistics for soil disposal and excavation.
Both above-ground and underground fuel storage tanks have their advantages and disadvantages, and the right choice depends on specific needs and considerations. Factors such as space availability, budget, safety, environmental impact, and regulatory compliance must be carefully weighed when selecting a fuel storage solution.

Fuel tank construction and safety
The design and construction of a fuel tank play a significant role in the safety of the system. Most intact fuel tanks are very safe, as the tank contains a fuel vapour/air mixture that is well above the flammability limit and, therefore, cannot burn. However, fuel tanks have been implicated in aviation disasters. Bladder tanks, or fuel cells, are reinforced rubberised bags installed in a section of aircraft structure designed to accommodate the weight of the fuel. One downside to this type of tank is the tendency for materials to work harden through extensive use, making them brittle and prone to cracking.
For underground fuel tanks, regular evaluations and professional assistance are necessary to maintain tank and soil conditions. Compressed natural gas (CNG) fuel systems require safety inspections and compliance with expiration dates. Above-ground fuel tanks offer convenience but also present risks such as fires, explosions, pollution, and theft. Double-walled tanks are preferable to single-wall tanks as they provide an extra layer of protection from leaks and punctures. Single-wall tanks are more susceptible to corrosion and leaks and must be located in a diked area that can contain 110% of the largest tank's capacity.
To ensure safety, construction sites should establish clear safety zones and prohibit smoking or open flames near fuel storage tanks. Regular inspections and the prompt replacement of worn-out parts contribute to the reliability of the fuel storage system. Seals, gaskets, and mechanical parts should be checked for degradation, and damaged components should be replaced. Remote monitoring systems can also be employed to enable immediate responses to emergencies and proactive maintenance.
When selecting a construction fuel tank, it is essential to consider efficiency, cost, and safety. Choosing a reputable manufacturer with a proven track record ensures a quality product, reliable support, and adherence to regulatory standards. Construction managers can also use fuel tank monitoring innovations to optimise fuel expenses and contribute to budget savings.

Placement and Construction
It is important to ensure that your fuel tank is properly placed and constructed according to safety standards and regulations. Above-ground storage tanks (ASTs) are generally preferred over underground storage tanks due to their ease of maintenance, relocation, and reduced environmental impact in the event of a leak. When installing a new tank, orient it in an east-west direction to minimise exposure to solar radiation, which can cause weathering and make the tank brittle over time. ASTs should only be used outdoors and should be placed in a clear area to facilitate inspections and reduce safety hazards.
Regular Inspections
Fuel tanks should be visually inspected regularly for leaks, spills, and damage. Check the pumping equipment, vents, valves, and pipelines weekly for any signs of leaks or damage. A more thorough physical inspection of the tank, including bolt tightness, paint deterioration, and the general condition of pumps, vents, and valves, should be conducted every six months. In harsh winter conditions, more frequent inspections may be necessary. After each inspection, record your findings and plan for any required maintenance or repairs.
Cleaning and Maintenance
Proper cleaning and maintenance of fuel tanks are essential to prevent blockages and ensure optimal performance. Filler caps should be cleaned using a wire brush, and a small amount of lithium grease should be applied to prevent rust build-up. The gasket at the bottom of the cap should be inspected to ensure a good seal. Vents and valves should also be regularly inspected and maintained to facilitate proper fuel flow. For ASTs, it is important to check weekly for water or product accumulation in the interstitial space and remove any rainwater, diesel, or other hazardous waste. Fuel quality should also be checked regularly to avoid using fuel that could damage the tank or equipment.
Safety Preparations
Fuel storage tanks should have adequate safety measures in place to prevent and mitigate potential emergencies. Fire-guarding or vaulting should be strong enough to prevent fuel ignition for at least two hours during a fire, unless the flashpoint is higher than 100 degrees Fahrenheit. Consider investing in a double-walled tank or including a secondary containment area to provide an additional layer of protection against leaks and spills.

Fuel tank capacity
In vehicles, fuel tank capacity can differ significantly. For example, in cars, the fuel tank capacity can range from small city cars with tanks of around 30 litres to larger vehicles with capacities of 60 litres or more. The placement of fuel tanks in cars is typically lateral, which helps maintain a steady fuel supply when driving on inclines or declines. Some cars, like the early Ford Model T, had fuel tanks located under the front seats, relying on gravity to feed fuel to the engine.
Aircraft fuel tanks can vary even more widely in capacity and design. Smaller general aviation aircraft like the Cessna 172 often use rigid removable metal tanks, while larger transport aircraft store fuel in the wings, belly, and sometimes the tail. Bladder tanks, made of reinforced rubber, are used in high-performance light aircraft, helicopters, and smaller turboprops. These bladder tanks allow for maximising fuel storage within the aircraft's structure.
For stationary fuel tanks, such as those used at gas stations or farms, capacities can range from 1,000 gallons for a small diesel tank to 5,000–35,000 gallons for larger stations, depending on their size and purpose.
The choice between above-ground and underground fuel storage tanks is also significant. Above-ground storage tanks (ASTs) are becoming the preferred option due to their reduced environmental risk, easier maintenance, and longer lifespans compared to underground storage tanks (USTs).
In addition to capacity, the design and construction of fuel tanks are crucial for safety. Factors such as the tank's material, the potential for fuel saturation, and the prevention of leaks and explosions are all critical considerations in ensuring the safe operation of fuel tanks.

Fuel type and water accumulation
Water can enter the fuel system of diesel engines from poorly maintained storage tanks at diesel fuel retailers. Diesel fuel is also mildly hygroscopic, meaning it attracts and absorbs moisture from the air. Regularly leaving water in the fuel system can cause numerous issues, including rust and corrosion, icing in winter, and microbial growth. Water pooling in the bottom of the engine can cause rust and algae, leading to microbe growth. Microbes and bacteria can multiply quickly in a dark and moist environment, bringing acids and corrosion that clog filters.
Oxidation and hydrolysis can occur when diesel fuel is exposed to oxygen and water, respectively, lowering fuel quality and creating gums and sludge that clog machinery. To prevent water-related problems, water dispersants are added to diesel-only fuel products. Water contamination of diesel fuel is such a concern that most diesel vehicles are equipped with a water separator in the fuel filter assembly or elsewhere in the fuel system.
Water accumulation can also be an issue in gasoline engines. In cold winter weather, accumulated water can freeze and cause issues such as blocking the fuel pump or hoses. To prevent this, it is advisable to keep the tank full, as this reduces the amount of condensation in the tank.
