How Deep are Gas Station Tanks Buried?

Most gas station tanks are buried between 8 and 12 feet below the ground. However, it is necessary to note that the depth of the tank is determined by a whole number of factors.

These factors might include the soil type, the surrounding groundwater level, or even the size of the tank. Nevertheless, note that the depth of the tank will have a massive impact on the price of the gas, as deeper tanks tend to be much more expensive to install.

Gas station tanks are placed underground since they are less likely to explode. Have in mind that most gas station tanks are around 12,000 gallons, but they can range from 6,000 to 18,000 gallons. You will also find far bigger tanks at truck stops and some rural stations.

According to experts, underground gas tanks can last long but the exact duration will depend on a wide range of factors. Have in mind that these factors will include the type of tank, the quality of the materials, the level of maintenance, and the environment in which the tank is stored.

Tanks buried underground tend to have a lifespan of 20 to 30 years, depending on the soil type and whether or not they were properly installed. Tanks installed in hot and humid climates, or even in areas with salt water, are known to have a lower lifespan. Corrosion and rust will also have a say in a tank’s life expectancy.

Top Reasons Why Gas Station Tanks are Buried Deep

  1. Regulatory Requirements

This is one of the most cognizant factors that will dictate how deep a tank can be buried. Have in mind that there are federal, state, and local regulations that will dictate how deep gas station tanks are buried in the United States. This will most definitely vary depending on the location where you intend to build your gas station. The essence of these regulations is to guarantee environmental safety, prevent leaks, and protect groundwater.

  1. Environmental Considerations

Owing to the growing effects of man’s activities on the environment, this is, without doubt, one of the most important factors to take into account since it will impact how deep the tanks are buried.

Environmental factors, like soil conditions and the presence of water tables, will dictate how far the tank goes underground. Tanks have to be buried at a depth that limits the risk of exposure to contamination of surrounding soil and groundwater.

It is recommended you carry out soil testing and analysis to evaluate the suitability of the site and note the right burial depth.

  1. Tank Type and Construction

Gas stations are known to use a wide range of tanks depending on their needs and capabilities. Tanks like underground storage tanks (USTs) or aboveground storage tanks (ASTs) will come with their own installation requirements. Also, the tank’s construction materials, design, and safety features will also have a say in the recommended burial depth.

  1. Structural Considerations

The stability and load-bearing capacity of the ground will factor into the tank burial depth. To guarantee that it is done right, the tank will have to be buried at a depth that guarantees adequate support to deal with the weight of the tank, the fuel it carries, as well as any other loads as a result of vehicles or structures above.

  1. Future Land Use and Accessibility

You will want to take into account the future use of the land as well as its accessibility when deciding on how deep to bury the tanks.

If you have intentions to inculcate future construction or development on the site, the tanks will most definitely have to be buried at a depth that gives adequate room for the installation of utilities, foundations, or other infrastructure while ensuring that you are in conformance with regulations.

Conclusion

Gas station tanks are more or less buried underground since they are less likely to explode.  Most gas station tanks are buried between 8 and 12 feet below the ground. However, it is necessary to note that the depth of the tank is determined by a whole number of factors.

Gas station owners and operators are advised to reach out to their local regulatory authorities and ensure that they are in adherence with industry standards and best practices when it comes to regulatory and environmental safety.
