Are Water Tanks Compulsory in Australia?

Water TankWater tanks are one of the best ways to improve the efficient use of resources in a home or building. Although you cannot use the supply for drinking, you can utilise it to water plants, flush the toilet, fill the swimming pool, and even wash your laundry. You can also drink it as long as the water is not contaminated. But do you need to have one in your home? It depends on where you live.

1. Queensland

The state no longer requires you to have a water supply system such as a water tank since February 2013. You also do not have to meet a minimum amount of saved water. Nevertheless, it still wants you to opt into the water savings plan of the local council you belong.

2. Victoria

It’s unclear whether Victoria’s rainwater tanks are mandatory, but the state encourages you to install one. Based on regulations, the rainwater tank should meet the 6-star standard, which means it should catch water within 50 square metres and should have a storage capacity of no less than 2,000 litres. Furthermore, the tank should be connected to your toilet to be used for flushing.

3. New South Wales

New South Wales makes it compulsory to have a water tank or supply system for new developments. The size depends on many factors including where you plan to use it and the location of the property. The government may also require you to obtain a BASIX (Building Sustainability Index).

Water tanks can cost hundreds to thousands of dollars, depending on size and installation fees, but you can make it more affordable by taking advantage of rebates and choosing the right size for your home. If you have limited space, slimline water tanks are a good choice since it is narrow. You can also pick one that’s modular.
