Underground vs. above-ground water tanks

When it comes to installing a polyethylene water tank in your home, there are a variety of different considerations that need to be taken into account. One of these is where the water tank will sit – whether above ground or below.

To help make this decision, here is a breakdown of the benefits that come with either option.

Above-ground tanks

These water tanks are an increasingly common sight across Australia, as they offer a cost effective way to gather and store water.

The advantages of an above-ground system mainly relate to the installation and maintenance of the water tank. Above-ground installation is much cheaper than underground to install, thanks to the ease of getting them into place without any excavation.

When it comes to maintenance, all water tanks will need to be periodically emptied and cleaned from the inside. With an above-ground tank, this process is much easier – simply hose down the inside and then tilt the tank to let the water drain out.

Underground tanks

Tanks installed under the ground, either partially or completely under the soil, are another popular option. By sinking these systems into the ground, families can enjoy more space on their property.

Underground tanks are also popular among home builders, as they can be installed during the construction phase. By integrating a water tank at this point, it is possible to minimise the installation costs. Above-ground systems on the other hand continue to be more popular with existing home owners.

Finally, it is important for underground tanks to be properly reinforced in order to handle a long life underground. A reinforced tank is essential for ensuring that it lasts as long as the rest of the property while handling the pressure that comes from an underground solution.

Choosing the right tank for your needs is easy, just make sure you understand the different factors that come with each alternative.
