Not Using Your Rainwater? That’s A ‘Pour’ Choice!

A way to save money and the environment, sounds difficult doesn’t it?  The two concepts are rarely connected. However a recent study has proved that it is possible to achieve both financial savings and environmental sustainability.

Water is arguably the most important resource in the world. Surely, this highlights need to secure our water supplies. With a growing population, such as that seen in Sydney, the relatively simple theory of preserving our societies water supplies and limiting individual usage is made much more difficult to implement and control.

Personally, I believe fresh potable water should only be used for drinking. Why do we waste such a precious limited resource on our gardens and for washing our cars? Surely recycled rainwater could be used for these activities?

A recent study in 2011 from the science journal ‘Resources, Conservation & Recycling’ analysed the ‘Water savings, Reliability and Economic Benefits‘ of rainwater capturing and re-use.

Rainwater can be captured and stored in rainwater tanks, with this process known as a rainwater harvesting system (RWHS). Rainwater can be captured from the roof of your house and stored in a rainwater tank. The tank’s outlet pipe can then divert rainwater to many household devices such as toilets, washing machines and can even be used throughout your garden.



Having studied and advocated such vital global issues for a number of years, this system is one you want to have installed in your home!

I’ve found that many individuals oppose sustainable environmental practices because they misunderstand the scarcity of water, its importance within society and the urgency required to address the problems. This leads to a belief that our water supply is secure and its management is unnecessary.

I strongly disagree. I believe our water supply does need to be managed for a secure water supply in the future. However to those who aren’t convinced, why not install a RWHS for personal economic benefit?

The benefits of a RWHS are not only restricted to the environment. Personal financial savings are a significant incentive for people to install these systems. Current NSW Government rebates for installing a Rainwater Harvesting System range from $100 to $500, depending on the size of the water tank, with an extra $500 if all toilets are connected to the system and a further $500 if your washing machine is connected to the system. Further financial savings will be observed through a smaller water bill, due to your reduced use of mains water.

Water is one of the most valuable resources in life and pressure is slowly being placed on our water catchments. Capturing, storing and re-using rainwater which falls on your property is a cheap, reliable and simple method to minimising your water bill and increasing your families, and your own, sustainability.
