How Much Can I Save?
Our Research Has shown that an average household using the Redwater Diverter system could save approximately 16,000 litres of water every year, that's approximately *9.3% of potable water used! These figures are only based on average daily usage. You could save even more than this!

To help save water, the Brisbane City Council  recommend residents have 4 minute showers. If you install the Redwater Diverter system the first half of your 4 minute shower won't be cold!

To test how much you can save, wait until the hot water pipes have cooled overnight, then use a bucket to catch the Redwater at the hot tap in your kitchen and bathroom. When the hot water arrives, turn off the tap and measure how much water is in the bucket.

If you waited at your kitchen sink for 1 minute, you could save approximately 9 litres each time you use the tap!

*The percentage was calculated using information from the Brisbane City Council advising that average daily water consumption for Brisbane households in April 2007 was 470 litres per day. 
How Much Will it Cost?
Depending on where your hot water system is installed, the average home would require a Redwater Diverter for the kitchen and one for each additional bathroom.

The investment in a Redwater Diverter is AU$110.00 RRP (GST inclusive). 

You will require a plumber to install each Redwater Diverter and return line. The averag installation would tak a plumber 1 - 3 hours. The cost of materials for the return line will depend on the size of your house and the length required. The return line can be polythene or polybutylene pipe which is cheap and quick to install.

Most plumbers have a piping system they are familiar with and should be able to make further recommendations.

Australian Achiever Award – WINNER Save Water Awards


This award recognises an individual who has made an outstanding contribution to water

conservation through initiative and leadership.


A passionate environmental and water conservation campaigner, Andrew Willsford

is credited with inventing , developing and funding the Redwater Diverter – a low

impact water saving plumbing device that features patented energy efficient


Cost effective and easy to install, the innovative Redwater Diverter retains any cool

water left in the hot water line that would otherwise be lost down the drain,

without the need for user intervention. This cool water can then be diverted to a

tank for re-use.

Compatable with many different types of plumbing systems throughout the world,

including those with low water pressure issues, this noise free device doesn’t

require a water pump, electronic sensors or pressurised bladders, which  makes it

an economical and efficient choice for households and businesses.

Importantly, the Redwater Diverter saves approximately 16, 000 litres of potable

water per annum in an average sized home with four occupants.

Andrew actively promotes his water conservation message throughout the

plumbing industry and wider community via a number of channels, including

website, social networking, media interviews, presentations to large water users,

and ongoing consultation with industry experts.

He has also lobbied the Queensland government to change legislation to include

re-circulation devices in the Sustainability Declaration when selling a home in

Queensland, and the Redwater Diverter is now incorporated into new housing and

building designs throughout Australia.

Andrew Willsford believes that being names finalist is heartening and validates

our achievements to date.

“This recognition is an opportunity for Redwater Australia to further promote and

empower the population to be self reliant and responsible for their water supply;

essentially changing their environmental behaviours to make water saving a

household expectation”, says Mr Willsford.
