When it comes to maintaining the integrity of your fuel storage system, one of the most critical challenges to tackle is keeping water from your tank. Water can wreak havoc on fuel quality and equipment, leading to operational inefficiencies and potential damage to the tank. In this article, we’ll delve into the reasons behind the presence of water in fuel storage tanks. We’ll also provide expert advice, backed by industry insights on effectively preventing water contamination. Safeguarding your valuable investment from water-related issues requires a proactive approach, and we’re here to equip you with the knowledge you need to ensure the integrity of your fuel storage.

The Water-Fuel Dilemma

As you’re bound to know, water and fuel don’t mix well – it’s a fact that can’t be overlooked. When water finds it’s way into your fuel tank, it can cause a range of issues, as listed below:

  1. Microbial Growth: Water provides a breeding ground for microbes, leading to bacterial and fungal growth. This can create a slimy layer at the water-fuel interface, clogging filters, and corroding equipment.
  2. Corrosion: The presence of water can accelerate the corrosion of your tank and other metal components within the fuel system. This not only compromises the structural integrity but can also introduce harmful particles into the fuel.
  3. Fuel Quality Degradation: Water in the fuel can lead to a phenomenon called phase separation, where the water and fuel separate into distinct layers. This affects the fuel’s combustion efficiency, potentially causing engine problems once pumped into the vehicle or machine.
  4. Freezing Issues: During colder months, water in the fuel can freeze and create blockages in fuel lines and filters, disrupting fuel flow and causing operational disruptions.

Prevention Tips from Fuelchief

At Fuelchief, we understand the importance of safeguarding your fuel supply from water contamination. Here are some tips to help you keep the water our of your fuel tank:

  1. Choose the Right Tank: Our first and foremost advice – choose a tank with a sloped floor, like our DC Range of tanks. A sloped floor means any water that does get in will gather towards one end of the tank, making it easy to remove via the suction pipe.
  2. Choose the Right Location: Ensure your fuel storage tank is installed on a level surface, away from potential sources of water runoff. A proper foundation and location can prevent rainwater from entering the tank.
  3. Invest in Quality Tank Seals: High-quality tank seals and gaskets are essential to prevent water intrusion. Regularly inspect and replace them if needed, as they can deteriorate over time.
  4. Regular Inspections: Schedule routine inspections to identify potential points of entry for water. Look for signs of corrosion, cracks, or weak seals that might compromise the tank’s integrity.
  5. Proper Ventilation: Proper ventilation can help manage humidity levels inside the tank, reducing the chances of condensation and water buildups. A well-ventilated tank minimises the risk of water contamination.
  6. Keep Tank Fill Points Covered: Ensure your tank has secure caps or covers for its fill points to prevent rainwater from entering the tank during refueling.
  7. Install Water Sensors: Consider installing water sensors or alarms that can detect the presence of water in the tank. These sensors can provide early warnings, allowing you to take prompt action before water contamination becomes a significant issue.
  8. Regular Maintenance: Follow a strict maintenance schedule, including tank cleaning and fuel quality testing, to detect and address any water-related issues promptly.



Water intrusion into your fuel storage tank can lead to a cascade of problems that affect fuel quality, equipment integrity, and over operational efficiency. By following the points above, you can take proactive measures to keep water out of your tank and ensure a reliable and contamination-free fuel supply. Remember, prevention is key. Invest in quality solutions such as tank with sloping floors, conduct regular inspections, and prioritise maintenance to safeguard your investment and keep your fuel storage system running smoothly.
