Underground Fuel Tanks

Underground fuel tanks are ideal for businesses that must store fuel, but have limited space. Fuel tanks that are installed underground provides convenience in storing huge amounts of fuel. Industries that utilize underground fuel tanks include trucking fleets, fuel suppliers or gasoline stations, and other businesses that need to store fuel for up to 200,000 liters.

However, underground fuel tanks are not all perfect, as they come with risks as well. Common problems include rust and corrosion, which are difficult to detect. This can lead to leakage of the fuel that may go undetected for a long period. Even the smallest leakage can cause huge damage and contamination to the environment, and is also prone to fire and other accidents. Clean up can be very costly. So, here are some tips to help you maintain and keep an underground fuel tank safe.

 

Follow Policies and Standards

 

If you are planning to install an underground fuel tank, make sure you meet the standards set by the authorities. Strict implementation of these standards ensure that underground fuel tanks are properly and safely installed. You should first consider the type of soil and water level of the ground before installation. A site with clay soils are not allowed to install underground fuel tanks, as clay accelerates corrosion. Sand is an inert material, which makes it ideal for underground fuel tank installation. Underground fuel tanks must be installed in an area with deeper groundwater level. It must not also be need any source of water.

 

Choose Bunded Tanks

 

Underground fuel tanks must bunded tanks that come in double walls, which offers more protection against any leakage and damage. Bunded tanks are typically made of steel. These tanks are built to last with the highest possible durability. If in case of any fuel leakage, the outer tank can hold the leakage in, preventing it from coming in contact with the immediate environment.

 

Regularly Monitoring

 

Regular monitoring of the underground tank is a crucial and necessary procedure. This is to prevent any problems, for example, detect leaks so that it can be inspected and examined, and then be addressed as soon as possible. A number of ways to monitor fuel tanks and detect leaks including ATG systems or automated tank gauging, stock inventory, and interstitial monitoring. Interstitial monitoring is the most advanced among these methods. It uses sensors that are installed between the walls of the tank.

 

Other Tips

 

Underground fuel tanks that are not used for six months must be taken out properly. Certain standards must be followed in doing this. Proper withdrawing of these tanks is extremely important to avoid soil contamination and other health risks. If you need help in installing and maintaining an underground fuel tank, contact your tank supplier, as they are the ones who know the appropriate storage system for your fuel tank.
