In an industrial setting, water tanks ensure that there's a ready reservoir to serve all the water demands should the taps run dry. These tanks can also hold water that is meant for re-purpose, such as in cooling towers.

After identifying your needs and how much water you need, you have the option of getting one large tank or multiple smaller water tanks. What should you consider when choosing one over the other?

Available Space

Which set-up would be an ideal fit for you, considering the amount of space available? If you have an apparent space limitation, then you may want to consider multiple small tanks. In this case, you may also want to look into water tanks that have a narrow width and extend high up.

Rainwater Harvesting Needs

You can harvest a lot more rainwater with multiple water tanks positioned at different catchment areas. This cannot compare to how much you'd collect with a single tank, especially when it rains only for a short time.

Separating Your Water

Depending on the end-use, you may need to treat some of your water and leave some of it as is. In this case, a single tank set-up simply wouldn't work, and you must get multiple water tanks.

You can maximise on just how much you collect by installing underground water tanks to collect water that would have otherwise run off into the stormwater drainage. You can use this water as is, for some purposes, or treat it.

Council Requirements

If you live in areas where the risk of a bushfire is classed medium or high, you are required to have a water retention tank to help with firefighting efforts. This is water that you should have at all times, and as such, it is best to keep it in a dedicated tank, separate from other water tanks on your property.

You should consult with the relevant authorities about details such as tank configuration and mandated capacity. These will, of course, depend on your location, and the size of your property.

Aesthetic Appeal

One large tank does not stand out quite as much as several water tanks lined up and interlinked. As such, if aesthetics is a concern for you, then you may want to consider a single tank set-up.
