What Are the Benefits of Having a Rainwater Tank

One in four Australian households have a rainwater tank installed. In recent years, more and more people have been harvesting rainwater as a way to help the environment. This is because it has many benefits, such as the following:

1. It Can Reduce Water Bill Costs

Installing rainwater tanks in your home is a great way to save money on your monthly water bill. Water bills are a major expense for many people, especially in drought-stricken Western Australia, which is currently facing a huge water crisis.

By installing a rainwater tank, you can then use this water to flush toilets and do laundry. You can also use it in your garden or give it to your pets.

2. It’s Environmentally Friendly

Collecting rainwater is an excellent way to reduce your environmental impact. This is because rainwater can be used for non-potable uses, like watering your garden or flushing your toilet.

This is better than sourcing drinking water from the main water supply. This is because you will not contaminate the drinking water and spread nitrate leaching into the waterway.

3. You Can Be Eligible for Rebates

Some states offer rebates to people who install a rainwater tank. You are eligible for a rebate if you install a rainwater tank of at least 900L. This encourages households to install rainwater tanks and save money on water bills.

The amount you can receive varies depending on which state you live in. For example, the government of Victoria will give rebates to households that install a 1,600L tank.

How to Install a Rainwater Tank

Installing a rainwater tank is a do-it-yourself (DIY) project, and it’s not difficult. Here’s what you need to do to get started:

1. Locate a Suitable Spot

The first step is finding an appropriate location for your rainwater tank. Ideally, the tank should be at least 20 metres away from the house and well-hidden. This is to avoid people tripping over it and damaging it.

The tank should be at least 1.8 metres above grade as well. This is because it prevents it from freezing in winter and also helps prevent damage if a tree starts to fall.

2. Choose the Tank Style

There are three main rainwater tanks to choose from: underground tanks, plastic barrels, and steel tanks.

Underground tanks are the most popular choice but also the most expensive. They are also more difficult to install because they require digging work. However, they provide a great service, as they are durable and attractive. They can also last for up to 25 years.

Plastic barrels are made from recycled plastic. They are inexpensive and usually large enough for most household uses. However, they are not as attractive as underground tanks.

Steel tanks are also a good choice, sturdy and long-lasting. However, they are more expensive than plastic tanks.

3. Choose an Installation Method

There are different methods you can use to install your rainwater tank. If you are installing an above-ground tank, you will need to choose an installation method that suits your garden, as there are many different designs available. If you are installing an underground tank, you will need to make sure that your tank does not leak.


Collecting rainwater is a cheap and renewable resource. Installing a rainwater tank at your home is a great way to help the environment—as well as help your budget.
