Above Ground vs Below Ground Tanks

Above-ground vs Below-ground Tanks – If you have been looking at water storage tanks, you will 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 few considerations, such as how much water is needed, space available for water tanks, and the budget for the project.

We are here to break down some advantages and disadvantages of above-ground and below-ground water storage tank options for the next project to narrow down the selection from the many options available on the market. Rainfall statistics for your location are available to view on the Met Office website.

Below Ground Tanks

Below-ground tanks are a great choice for water storage, depending on the project’s requirements.


  • 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 the more extreme weather, as they will remain sheltered from freezing or hot temperatures. This can help prolong the life of the tank as it will not be susceptible to harsh weather damage and are also safe from other outside risk factors such as vandals or strong winds.


  • 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.  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.

Above Ground tanks


  • Easy installation – installation of above-ground tanks is much simpler than a below-ground tank as fewer plumbing parts are 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 which helps reduce 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. Additionally, above-ground tanks can be transported if the owner or business needs to stop the project or move homes.


  • Insulation: Lack of insulation can cause the water inside the tank to get very cold dusting the winter, however, we have options for insulating these tanks here.
