Water tank size and capacity will greatly differ depending on your use, water harvesting method and, area that you have available. That is why we have decided to compile a list of our water tanks, their sizes, colors, and capacities so that you can make an informed decision when purchasing your first tank!

Water tank sizes and capacity

What is the difference between water tank size and capacity?

Usually, the size of the tank refers to the physical dimensions of the tank. The length, height and/or diameter of the tank. The capacity refers to the amount of water or liquid that can be stored in the tank. Therefore, it is important that you ask for both the water tank size and capacity to make an informed decision on whether you want to buy the tank.

Plastic Water Tank vs. Steel Water Tank

It is important to take the material of the water tank into consideration when purchasing your water tank. The bigger the water tank size, the more pressure it will take from within the tank when it is filled with water.

Therefore, we highly recommend steel tanks. They are sturdy and durable.

Why buy a steel water tank?

  • Durable (20 years pro-rata leak-free warranty)

  • Strong. Will not bulge, buckle or break under pressure from within the tank or outside the tank

  • Cost Efficient. Comparing the lifetime to the price, the steel water tanks are much more affordable compared to plastic water tanks.

  • Easily Transported. Steel water tanks are easily transported due to the fact that they can be flat packed are manufactured in parts instead of one complete tank like most plastic tanks in the market.

  • Aesthetically pleasing. The Steel water tanks look elegant, sleek and have a range of colours to choose from to fit in with the surroundings. The colour of the steel water tanks will not fade, become brittle or be impaired in any way during the course of the tank lifetime.

  • Fire Resistant. While plastic might melt into a pool of gunk, steel tanks are resistant. It will heat up, but will not bulge and break when surrounded by fire.

How do I choose a water tank?

Choosing a water tank can be a lengthy process, but it doesn’t always have to be. When you know what to look for, you can make a decision relatively quickly regarding what tank you need.

Ask yourself the following questions when you are looking at purchasing a water tank:

  • How much space do I have?

Firstly, your space constraints might be a big issue. Especially in complexes with small gardens. Make sure you know exactly how much ground space you have available for a water tank. That way, you can consult your sales agent and inform him of the exact water tank size limits you have.

  • What colour can I get?

Some complexes in cities have very strict guidelines on colouring for water tanks and other additions to the complex. Therefore, ensure you know your residential area’s rules and regulations regarding the colours that you are allowed to have.

Furthermore, various colours may lead to different consequences (especially in plastic water tanks), we will briefly discuss this phenomena below.

  • What will the tank be used for?

While the most frequent use for tanks is water storage and water reservoirs, there are many other uses for storage tanks.

Ensure that you check that the tank is suitable for the specific need that you have. As an example: chemical storage requires a specific coating ( Thermally bonded epoxy) to make it highly corrosion and chemical-resistant. Therefore, buying a traditional steel water tank without these coatings may lead to some dire consequences.

Ensure that you speak to your sales representative regarding the use for the tank when purchasing a storage container/tank.

Choosing a water tank

Best colour for water tank

Choosing the “right” colour for your water tank is not as important when you are looking at buying a steel water tank. This is due to the fact that our steel water tanks are designed in such a way that they ensure that the water stays as cool as possible.

However, if you are looking at buying a plastic water tank, you need to ensure that you choose the right colour. Here are some basic assumptions that you can make based off of the plastic water tank’s colours:

  • Darker Colours (Black, dark blue, grey)

The darker colours will heat up your water. Therefore, if you are using water from the tank, straight to the tap, this might pose a concern. Furthermore, dark and warm environments are optimal for the growth of algae.

  • Lighter Colours (White, cream)

Lighter Colours will keep the water cooler, or at room temperature at least.
