We all love rainy days in Australia. The smell of rain, cosy couch time, sounds of raindrops on the roof and also possibly a rainbow outside your window. You can make use of the rain water by capturing some of it in a water tank. Not only will this help you cut some of the water bill, it will also reduce your environmental footprint.

Here at Malvern Irrigation, we have water tanks in all shapes and sizes, helping you make use of even a small urban space. Let’s look at some of the best water tank options for your home.

Is the Water for Indoor or Outdoor Use?

One of the first things you need to consider before buying a water tank is how you would like to use the water. The easiest way to start is by getting a water tank for outdoor use like watering the garden or washing the car because you will probably just need us to install the tank and not have to worry about any plumbing work.

You can save even more by sending this water to your washing machine, toilet or even hot water systems. However, this will require some work from a licensed plumber so that the tank is connected to your mains. But you don’t have to worry about that – just get in touch with us on (03) 9576 2344 and we’ll sort everything for you.

What Size Water Tank do you Need?

The capacity of the water tank really depends on the size of your garden or household. Slimline tanks are ideal for narrow spaces, while round, squat tanks are good for fitting under a deck. While a bladder storage system or underfloor tank is a good way to save space and keep the tank out of sight, it can be a bit more expensive.

You will also have to consider your roof area as well as the annual rainfall your region receives. We can help you configure the best water tank for your household.

Know About the Material of Water Tank

Here at Malvern Irrigation we have water tanks in all of the popular materials. Here are some of the common materials our customers ask for:

Metal Tanks

Metal Tanks are made from flat rolled or corrugated metal, which is usually coated or galvanised. These tanks come with plastic inner linings known as aquaplates. The aquaplates help increase the life of the tank as well as protect the quality of the water stored.

Polyethylene (Plastic)

This is perhaps the most popular kind of water tank. They are popular because of their durability and relatively low cost. With plastic, rust is not an issue. Some other synthetic materials are used for bladder storage, such as PVC and geotextile. Bladders are particularly useful to store water below a floor or deck. While the material is touch, it is not designed for outdoor installation.


Fiberglass tanks are designed to withstand extreme temperatures and are chemical and rust resistant. However, they are not the cheapest option and more suitable for installations above ground, unlike most of the other options that can be installed below ground.


Concrete tanks are more popular for industrial or agricultural use as they won’t rust, blow away, melt or burn. While these tanks can be bought ready-made, they are more common to be custom made onsite.

With so many options available to you, it can be a little confusing. Get in touch with me and we can help you find the perfect water tank for your home. Have a look at our Water Tank Brochures for more information.
