Choosing and installing a rainwater tank

There are a number of factors to consider when choosing a rainwater tank to install on your property, including tank size and rainfall as well as the tank material.

Investing in a rainwater tank means you’ll reduce your water bill and help preserve one of our most precious resources. To guide you in choosing a tank that best suits your situation, we’ve put together some points for you to consider.

Tank size and rainfall

The first decision you’ll need to make when purchasing a tank is the size. Ask yourself these questions to help you pick the right one:

  • How often will I be using the rainwater held in my tank?
  • How much rain does the area I live in typically receive?
  • How much space do I have around my home for a tank?
  • Will my tank require any structural support?

Tank material

The type of material you select for your tank will depend on its specific purpose.

Installing a rainwater tank

It's important that rainwater tanks are installed properly so that they are both cost efficient and meet regulations. Here's how to go about the installation process the right way.

When setting up a rainwater tank, there are a number of points to consider in order to make it cost efficient and meet regulations.

Touching base with your local council should be your first point of action so that you can check your plans are up to code. You may also need to lodge a Development Application and have your rainwater tank inspected by the Building Commission NSW (Click here for more information).

Things to consider

You should also consider the following before moving ahead with installation:

  1. Have the tank installed by a plumber or the tank manufacturer. This will ensure the system operates efficiently and is easy to maintain. By law, a licensed plumber is required wherever a tank is connected to the mains water supply, such as a tank to toilet system. A plumber is also required to connect your gutters to your tank and install an overflow to the stormwater system.
  2. Plumbers can also advise on the best location to maximise catchment.
  3. If your tank is going to be large, consult a builder or engineer as it may require structural support.
