Everything You Need To Know About Underground Oil Tanks
Are you thinking of buying a house with an underground oil tank? Maybe you want to replace an above-ground oil tank with an underground one? This blog will tell you everything you need to know about underground oil tanks, from installation and maintenance to removals and disadvantages. Keep reading to find out more.
Installing an Underground Oil Tank
Underground Oil Tanks require more planning for installation than above-ground tanks due to regulations and safety considerations. Once you have decided you want an underground tank, make an appointment with an OFTEC Technician for an Installation. The technician will assess the area, suggest the best site for your tank, and recommend plastic or steel. Once selected, a pit will be made to house the tank, which will be carefully lowered into the hole. Ventilation and fill pipes will be installed, and all home appliance connections will be checked. Finally, the pit will be filled in, and the tank will be tested to ensure full functionality.
Maintaining an Underground Oil Tank
Due to their hidden nature, underground tanks are more susceptible to corrosion and leaks without visible signs in comparison to aboveground tanks. Regular Oil Tank inspections are crucial to catching potential issues early. Inspection methods often involve pressure, ultrasonic, and soil testing to check for leaks or contamination. Maintenance tasks, such as cleaning and repairing, can be more complex due to the need for excavation to access the tank. Maintenance work involves more effort and cost compared to above-ground tanks.
Here are some ways you can be proactive in checking and maintaining your oil tanks’ condition:
- Regular Inspections: Schedule OFTEC Technician inspections to check for signs of corrosion, leaks, and structural damage. Early detection can prevent costly issues.
- Leak Detection Tests: Regular tests can help you to identify the early signs of a leak. Certified OFTEC Technicians can perform pressure, ultrasonic, and soil testing around the tank.
- Proper Ventilation: Ensure proper ventilation to prevent the buildup of fumes within the tank, which can cause pressure problems.
- Fill Level Monitoring: Keep track of your oil levels to avoid overfilling, which can lead to spills.
- Refilling: When refilling the tank, use a licensed oil delivery company. Avoid running the tank too low before refilling to prevent condensation and the introduction of water into the tank.
Removing an Underground Oil Tank
If you decide to remove your underground oil tank, follow these steps:
- Contact a certified OFTEC Technician to assess the tank and guide removal procedures.
- Check local regulations and obtain any necessary permits for tank removal. Underground Oil Tank removals can be more complicated and pose more significant environmental risks.
- The technician will ensure the tank is completely drained of any remaining oil and cleaned to minimise environmental impact. Oil can be stored in temporary storage and transferred to a new tank if you want an oil tank replacement.
The tank will then be carefully removed, ensuring the surrounding soil is properly managed to prevent contamination. If soil contamination is detected, measures might be needed to restore the area’s environmental integrity and avoid fines.
The Lifespan of an Underground Oil Tank
The average lifespan of an underground oil tank can vary widely depending on factors like material, installation, and environmental conditions. Generally, well-maintained oil tanks can last around 15 to 20 years. However, as tanks age, the risk of corrosion and leaks increases, especially underground ones. When your underground oil tank reaches 15 years old, you must pay extra attention to its condition to avoid an undetected leak.
Benefits and Disadvantages of an Underground Oil Tank
Benefits of owning an Underground Oil Tank
- Space-Saving: Underground tanks don’t take up any space in your garden, as they are buried in a hole underground. Putting your tank underground allows you to enjoy all areas of your garden.
- Well-Hidden: Burying your oil tank allows for it to be well-hidden underground. You do not need to worry about finding ways to Camouflage your oil tank (link to blog) with shrubs, fencing or covers to ensure it is more ‘aesthetically pleasing.’
- Weather Protection: Storing your oil tank underground shields it from harsh weather conditions, reducing the risk of damage, such as corrosion caused by condensation.
Disadvantages of owning an Underground Oil Tank
- Environmental Concerns: Like above-ground tanks, underground oil tanks can still leak and contaminate surrounding soil and water sources. Being hidden confidential makes it harder to spot signs of cosmetic damage or early leakages and could cause more significant damage if they go undetected.
- Maintenance Costs: Keeping an oil tank in good condition requires regular expenses for inspections, tests, and potential repairs. Underground oil tanks can be more expensive as specialist equipment, more vigilant plans and more time often needs to be spent on them.
- Removal Complexity: When the tank reaches the end of its life, removal can be costly, time-consuming and involve soil protection efforts. We suggest regular inspections and booking a removal to ensure maximum efficiency.
Ready to Install your new underground oil tank?
In conclusion, underground oil tanks offer discreet and space-saving heating solutions. However, their maintenance and installation require careful planning and adherence to regulations. You can make informed decisions prioritising functionality and environmental responsibility by understanding the benefits and challenges of Underground Oil Tanks.
