Rainwater Tank: Different Materials for Different Types

Rainwater TankTo ease the demand for water, people are learning to find alternative means to find a clean and consumable source. Some go down and dig wells, while others look up and consume rain.

In Australia, installation of rainwater tanks is becoming the standard, and manufacturers are shelling out a variety of choices for homeowners to choose from for their needs.

Planning to have one for your home? Here are some of the most common tank types you can consider.


Concrete tanks are the most expensive to install because it requires you to dig underground. Therefore, it is important to be aware of building and installation regulations in your community before opting for a concrete water tank. This type of container is suitable for properties that do not have enough outdoor space.


Metal tanks placed above ground are a great and more affordable alternative to concrete tanks. Its lightweight feature makes it easier to install. Nowadays, aluminium is the primary building material for metal tanks because it is less prone to rusting as compared to galvanised steel coated with zinc.


Fibreglass is a mixture of plastic and glass fibres making it durable and rust-proof. However, because of its material components, fibreglass cost more than metal and plastic tank alternatives.

Polyethylene (Poly)

Poly is lighter than metal, which makes it easier to transport and install. It is also rust-proof which makes it a very popular choice among homeowners. However, too much exposure to sunlight can make poly tanks brittle and break over the years.


Bladder tanks are becoming increasing popular especially for properties that have irregular spaces. You can install this depending on your need and preference. The only drawback is it cannot hold as much water as traditional tanks.

Based on the different tank materials listed above, have you found the right one for your home?
