If you’ve discovered an old underground fuel tank on your property—or you’re wondering what to do about one you’ve known about for years—you’re not alone. Many homes and commercial sites across the country still have buried tanks from earlier heating or fueling systems. But when it comes to removing them, confusion often sets in. What are the rules? Is it dangerous? Who do you call?
Here’s a breakdown of the most common questions and concerns about underground fuel tank removal, so you can make informed, confident decisions.
Why Were These Tanks Buried in the First Place?
Decades ago, burying fuel tanks was the norm. It kept the tank out of sight, protected it from weather, and helped conserve space on smaller lots. However, early tanks—especially those made from bare steel—were vulnerable to rust and corrosion over time. This led to leaks, contamination, and today’s environmental concerns.
Now, most new tanks are installed above ground or are made from more durable, protected materials.
Do I Need to Remove My Underground Tank?
There’s a good chance that you do, especially if:
- The tank is no longer in use
- You’re switching to a different heating source or fuel type
- You’re selling your property and the buyer requests removal
- Your insurance company or local government requires it
- The tank is over 20–25 years old and hasn’t been inspected
Even if a tank hasn’t leaked, its age alone may be a reason to remove it before corrosion sets in.
What’s Involved in the Removal Process?
Removing an underground fuel tank is a careful process guided by safety and environmental regulations. Here’s what usually happens:
- Permits and planning: Local permits are secured, and the tank location is confirmed.
- Tank cleaning: Any remaining fuel or residue is pumped out and safely disposed of.
- Excavation: The soil around the tank is carefully removed, often using machinery.
- Tank removal: The tank is extracted and inspected for leaks or structural damage.
- Soil testing: Nearby soil is analyzed for any signs of contamination.
- Backfilling: The area is filled and restored to match the original landscape.
- Documentation: You receive paperwork showing the tank was removed and handled properly.
Professionals handle all of this, making the process efficient and low-risk for property owners.

What If the Tank Has Leaked?
If the soil test reveals contamination, the next step is remediation. That can include:
- Removing affected soil
- Treating the ground with neutralizing agents
- Installing monitoring wells if required by regulation
- Filing reports with local environmental agencies
The extent and cost of cleanup depend on how long the leak was present and how far it spread. Early removal often prevents these complications.
Is It Safe to Leave the Tank in the Ground?
In most cases, no. An abandoned tank can rust, collapse, or leak without warning. Even if you drain and seal it, it still poses long-term environmental and property risks. Some local codes allow “closure in place,” but this is typically reserved for hard-to-reach tanks or specific conditions—and still requires thorough cleaning and filling.
Complete removal is usually the safest and most compliant option.
What Should I Look For in a Removal Contractor?
Fuel tank removal should be done by professionals with experience in environmental safety and regulatory compliance. Look for:
- Proper licensing and permits
- Experience with both residential and commercial removals
- A clear process for soil testing and reporting
- Equipment for safe excavation and disposal
- Liability insurance in case of unexpected damage or findings
Don’t cut corners—poor removal can lead to serious fines or unresolved contamination.

How Long Does the Process Take?
For most residential tanks, the removal process takes one to two days. If contamination is found, remediation may extend the timeline by days or weeks depending on the severity. The permitting process may also add a few days upfront, so plan accordingly if you’re working on a real estate or renovation deadline.
What Happens to the Tank After Removal?
Tanks are typically taken to a licensed recycling or disposal facility. If the tank is contaminated or contains hazardous residue, it will be handled according to state or federal waste management rules.
Your contractor should provide a final report that includes:
- Photos of the removed tank
- Soil test results
- Disposal documentation
- Any remediation plans, if needed
This paperwork is essential if you’re selling your property or need to show compliance.
Make a Smart Move for Safety
Whether you’re removing a tank out of caution or necessity, it’s a smart step toward maintaining a safe, clean, and future-ready property. Tanks don’t last forever—but removing them the right way ensures peace of mind for years to come.
