Above-ground vs. Below-ground Water Storage

Above-ground vs. Below-ground Water Storage

If you've been looking at water storage tanks, you'll find an almost overwhelming number of options. Different materials and methods are available to ensure that whatever the usage, the product provided will be appropriate for the purpose. This involves a number of considerations, such as how much water is needed, space available for water tanks, city bylaws and regulations, and the budget for the project.

We're here to break down some advantages (and disadvantages!) of above-ground and below-ground water storage tanks. This is to help readers get a better idea of what they might need for their next project and help narrow down the selection from the many options available on the market.

(1) Below-ground Tanks

Below-ground tanks are a great choice for water storage, depending on the client's needs and wants. Advantages of below-ground tanks include:

• Space saving: underground tanks will avoid having a large space taken up. This is especially important if you live in an area with little lawn space or less-than-ideal storage areas. In some cases, it might not be an option depending on the size and configuration of the tank needed.
• Insulation & Security: tanks situated below the ground will avoid more extreme reactions to weather, as they will remain sheltered from freezing or hot temperatures. This can help prolong the life of the tank as it won't be susceptible to UV damage or other harsh weather damage that can cause deterioration. Tanks are also safe from other outside risk factors such as vandals or strong winds.

Disadvantages of below-ground tanks include:

• Cost: The advantages of below-ground tanks do come with an additional cost. Digging, plumbing, and the associated costs of having professionals install the tank can be significantly more expensive than an above-ground tank. Accessories such as a water pump may also be necessary if this route is taken, so these additional costs should be considered against the overall budget for the project.
• Maintenance: As much as the underground location of the tank can help to protect it, it also makes the tank more difficult to access for repairs if they are needed.

(2) Above-ground Tanks


• Easy installation: installation of above-ground tanks is much simpler than a below-ground tank. Fewer plumbing parts are typically needed when installing this type of tank. Additionally, gravity can sometimes be used to deliver water to the home for use or link to a rainwater harvesting system for collection; this can help cut down costs as well.
• Affordable: A lack of digging to place the tank and the need for fewer accessories means that this option is typically cheaper than using and installing a below-ground tank.
• Flexible location: above-ground tanks are easier to find a location for, as things like gas lines or sewage systems don't have to be considered when finding a spot to place the tank. Additionally, above-ground tanks can be transported if the owner or business needs to stop the project or move homes.


• Security: evidently, above-ground tanks are slightly more prone to damage from weather, including UV-rays and freezing conditions. This should be strongly considered if the owner lives in an area that experience harsh weather, as the tank could be susceptible to damage this way if not maintained properly.
• Insulation: Lack of insulation can cause the water inside the tank to get very hot or cold depending on the weather. It can be very costly to insulate a tank to avoid this.
