Consideration Factors For Picking an Underground Water Tank

Underground Water Tank

Only 1% of the water on the earth is available for use, which is why water accessibility is becoming more of a challenge. It’s a good idea to harvest water using an underground water tank. This article will cover some of the most critical factors you need to consider when selecting one of these. 

Corrosion resistance 

Your tank should be able to withstand rust and corrosion. If the material that forms your tank corrodes, it will contaminate your water, causing a significant health risk. Ensure you choose a material like fibreglass, which will resist this corrosion.


Your tank should be constructed so that it prevents foreign objects and outside substances from contaminating the water. It’s important to incorporate features such as:

  • Screened ventilation openings 
  • Rain cover
  • Closed lids 

Adding these features will ensure that no unwanted particles make their way to your tank to prevent contamination. 

Size of the tank 

Your tank should be just the right size to hold a sufficient water supply to meet all your household needs. So, determine how much water you use per day and choose a tank that will give you an adequate supply. 

In addition, once you’ve fitted the tank, it will be tough to replace it. That’s why you have to pick the correct size from the get-go. 

Space available 

Along with the size, you have to consider how much space you have available to fit the tank and all the other fittings that come along with it. 

Tank use

Tanks for underground water have different purposes. You need to choose a tank that matches your needs. For instance, some tanks are explicitly designed to store drinking water, while others may only be for irrigation purposes. If you use the wrong kind of tank for your drinking water, you may accidentally poison yourself. 

If you aren’t sure which tank to get, consult a professional to help you determine the best type of tanks for your needs. 

Design of the tank 

There are several different designs for underground water tanks. The type of design you choose will depend on the use of your tank and the size of your storage area. So talk to a professional to help you determine the best tank design for your space. 

Type of soil 

The type of soil in your yard will also determine the kind of tank you can get. Loose, easy-to-dig soil can accommodate a taller tank that goes deeper into the ground. On the other hand, if it’s rocky, a tank that extends sideways and doesn’t have to go deep may be more suitable. 

Also, if your soil type retains a lot of water, choose an impermeable material like plastic so the dirty water won’t seep through. A metal tank in a wet area will rust, creating openings for external contaminants to get into the water. 

Cost of purchasing and installing the tank

Another major deciding factor is how much you will have to pay to get it up and running. This will determine the type of tank, the material you choose, and how big your tank is. 

However, while the upfront cost can tend to be high, long-run savings come into play. So don’t back away from installing your tank on account of upfront cost alone.
