How do rainwater tanks work?

 

The most basic answer to this question is that rainwater tanks work by storing rain water when it falls. They usually do this by reconfiguring your gutters to direct rainwater into a storage tank. This water can then be used on your property to shower, flush your toilet, water your garden or even do your laundry. 

 

Should I buy one?

Yes! Every household can benefit from installing a rainwater tank. Installing a rainwater tank can help you to save water, reduce the costs of your water bills and reduce the strain on municipal stormwater systems. 

 

They’re also a great solution for limiting water usage – this is especially valuable in Australia, where water is often in short supply and water restrictions are often in place. 

 

Getting the best performance from rainwater tanks

To maximise the storage capabilities of your rainwater tank, you’ll need to install your tank in the right location and you’ll also want to ensure that your roof design and downpipes are correctly designed. Installing accessories like a slow dripper line to your garden can also help you to get more from your tank. 

Before you install, here’s a few things you should keep in mind:

 

Placement of rainwater tanks

There are generally three ways that a rainwater tank may be installed on a property:

  • on the ground
  • on a stand
  • Partially underground

Regardless of where you choose to install, all rainwater tanks will need a flat, stable base.

 

Tank size

Rainwater tanks come in all shapes and sizes. Before installing a rainwater tank, you should think about how much catchment area you have on your roof, as well the space available on your property and the water usage of your household. A larger tank could supply your home for a considerable amount of time, even if rain is limited during certain parts of the year – but you may not have the space available on your property! To work out the right tank, you’ll first want to figure out how much room you have, before calculating how much water your family uses in a week. Generally, it’s best to aim for a water tank capable of holding around a month’s worth of water.

Building regulations

There are rules and regulations regarding rainwater tanks, but these vary between councils, so you’ll need to see what is relevant for your local area. In some areas, you may be able to get a rebate towards the cost of purchasing and installing your rainwater tank.
