Under or Above Ground Tanks: What Factors Should Determine Your Choice?

One of the best ways to store water in your home or commercial property is to install a water tank. But before you go shopping, there is one essential decision you have to make – will you buy an aboveground or underground water tank? Either of the options can be suitable. To help you make an informed choice, this post will share numerous factors that will help you choose between above and underground water tanks.


If you have decided to buy a water tank, you want your investment to last for many years. The tank's lifespan will be determined by the type of water you store (soft or hard), the tank's material and where you install it. For instance, aboveground tanks are exposed to environmental elements like the rain, sun, wind and snow, which have a negative impact on the tank. Since most tank materials cannot resist these weather conditions for long, the tank will depreciate faster, and the quality of water may eventually be compromised, as well. However, you will not experience these issues when you install an underground tank regardless of the tank material you choose.

Installation and maintenance budget

The expenses linked with buying and installing underground water tanks is higher compared to an above-ground tank. Other than procuring a tank that's made of high-quality materials, excavation work has to be done to install the tank. This means specialised material, labour and permits will be required. The installation will cost more and will require extra time. Installing an aboveground tank, on the other hand, is easier and less costly.

Repairing or maintaining an aboveground tank is also simpler and less expensive compared to what you will pay for an underground one. While an underground tank is protected, it will be challenging for the repair specialist to access and service it. The good news is that such tanks rarely get damaged.


Another essential factor you must consider is the available space in your compound. If you have plenty of space in your backyard, you can opt for an aboveground tank. Having limited space, however, doesn't mean that you cannot install a tank. You only need to excavate the ground under the yard or driveway and install an underground tank. This way, you will still have a sufficient supply of water in your home, thanks to the water tank, and retain the aboveground space.

Before you install a new tank in your compound, be sure to consider these outlined factors to make an informed decision.
