Above Ground vs. Below Ground Water Tanks: Pros & Cons To Consider

Above Ground vs. Below Ground Water Tanks

Above ground and below ground water tanks both have their advantages and disadvantages. Choosing the right type of water tank for your specific needs can be a crucial decision, whether you’re looking to store water for personal or commercial purposes. In this article, we’ll explore the pros and cons of each type of tank to help you make an informed decision.

Above Ground Water Tanks

Above ground water tanks are a popular choice for many homeowners and businesses. Here are some of the advantages and disadvantages to consider:


  • Easier and cheaper to install than below ground tanks

When it comes to installing a water storage tank, above ground tanks are generally easier and more cost-effective to install compared to below ground tanks. They can be placed on a suitable flat surface, such as a concrete slab, that doesn’t require any special preparation. This means that the installation process is generally faster and less disruptive than that of below ground tanks.

  • Can be placed above ground in a variety of locations

Above ground tanks are also much more versatile when it comes to placement. This means that you can choose to place your tank in a location that is most convenient for you, whether that be on your roof, in your basement, or in a corner of your backyard.

  • Easier to inspect and maintain

One of the biggest advantages of above ground tanks is that they are easier to inspect and maintain. Since they are visible and accessible, any potential issues can be identified and resolved quickly, without the need for expensive excavation work. This is especially important for those who rely on their water storage for everyday use, as regular maintenance can ensure the longevity and effectiveness of the tank.

  • May offer greater flexibility in sizing and configuration

Finally, above ground tanks may offer greater flexibility in terms of sizing and configuration. With above ground tanks, you can choose from a range of sizes and shapes, which means that you can find a tank that fits your needs perfectly. Whether you need a small tank for personal use or a larger tank for commercial purposes, above ground tanks can provide the flexibility you need to get the job done.


  • More vulnerable to weather-related damage

Since above ground water tanks are exposed to the elements, they may be more susceptible to damage from strong winds, hail, and other severe weather conditions. This can potentially result in costly repairs or even the need to replace the tank altogether.

  • May be more visible and unsightly

Depending on the location of the tank, an above ground system may not blend in with the surrounding environment and may be considered an eyesore. This is especially true if the tank is placed in a highly visible area, such as a front yard.

  • May be more susceptible to theft or vandalism

Above ground water tanks are more accessible than below ground tanks, which can make them a target for theft or vandalism. This can result in not only the loss of valuable water but also the need to repair or replace the tank.

  • May require additional heating or insulation in cold climates

If you live in an area with harsh winter weather, an above ground tank may require additional insulation or heating to prevent freezing. This can add to the overall cost of the system and may be a significant factor to consider when deciding between an above ground and below ground tank.

Below Ground Water Tanks

When it comes to water storage options, below ground water tanks have their own set of advantages and disadvantages. Here are some of the potential benefits and drawbacks to consider before making your decision:


  • Better protection from weather-related damage and vandalism

Because below ground tanks are shielded from the elements and located out of sight, they are less likely to be damaged by severe weather or intentionally harmed by vandals.

  • More discreet and less visible

Below ground tanks offer a discreet option for water storage that is tucked away out of sight. This can be ideal for homeowners or businesses that want to maintain the aesthetics of their property.

  • Can help maintain a consistent temperature

Water stored below ground can help maintain a more consistent temperature compared to above ground tanks, which may be subject to temperature fluctuations.

  • May be a good option in areas with limited space

For properties with limited outdoor space, below ground tanks can be a practical option as they don’t take up valuable surface area.


  • More expensive and time-consuming to install than above ground tanks

One of the major downsides to below ground tanks is that they are typically more expensive and take longer to install than above ground options. This is because excavation and site preparation is required, which can be a labor-intensive process.

  • More difficult to inspect and maintain

Unlike above ground tanks, it can be more difficult to access below ground tanks for inspection and maintenance. This means that regular upkeep and repairs may require additional time and resources.

  • Can be more difficult to access for repairs or cleaning

If a below ground tank requires repairs or cleaning, accessing it can be more difficult and require specialized equipment. This can add to the overall cost and time involved in maintaining the tank.

  • Sizing and configuration may be more limited

Because below ground tanks are typically more complex to install, there may be limitations on their size and configuration. This means that they may not be the best option for those

Key Takeaways

When it comes to choosing between above ground and below ground water tanks, there are many factors to consider. Above ground tanks are easier and cheaper to install and offer more flexibility in sizing and placement, but are also more vulnerable to weather damage and may be more unsightly.

Below ground tanks, on the other hand, offer better protection and temperature control, but can be more expensive and difficult to install and maintain. Ultimately, the choice will depend on your specific needs and preferences. By weighing the pros and cons of each option, you can make an informed decision that will best meet your water storage needs.
