Use 70% Less Water With Automatic Recycling Shower


Did you know that conventional showers send about 19,000 gallons of water down the drain every year?

There are lots of ways to reduce personal water consumption. You could take shorter showers, install a low-flow shower head, or use a shower bucket to save falling water for other uses in your home and garden.

But these changes require resources, tools, and more importantly, time and effort.

What if your shower could just save water automatically?

An Australian company is winning awards left and right for a shower design that does just that.

CINTEP’s water recycling shower will look and feel just like a normal shower, but will use 70 percent less water than conventional designs.

VentureBeat explains:

The recycling shower captures used water in a reservoir, which is likely to be built into the base of the shower. The water is then filtered in a component called a hydrocyclone, which uses similar technology to a Dyson vacuum cleaner, and spins the water around to separate out any heavier particles or materials. The 70 percent of the water that survives this filtering mechanism is pasteurized to kill any bacteria and redirected back into the shower head. The whole real-time, recycling process takes a mere 25 seconds and reduces the amount of water used in an average shower by 70 percent. Since you are recirculating water which is already warm, energy costs are further reduced over heating cold mains water.

Because the water is recycled, the shower puts out a decent flow at the rate of about 9 liters of water per minute, while only actually using about 2.7 liters of water per minute.

The shower is still under development but the company’s website states that it is expected to be on sale by the end of 2011 in Australia, the USA and throughout Europe.

Although it’s likely to come with a steep price tag, the recycling shower will cost less to install than a conventional shower, will reduce the demand on your hot water system by up to 50 percent and should save an average family of 4 about $937 every year. This means that on average payback will be less than 3 years and can be as little as 9 months.

My first design for such a shower is now 13 years old.

Mine was inspired by my daughter, who fet that it was time to turn off the shower when the water got cold. It was designed to run as a normal shower for cleaning, then recycle and filter as a shower for comfort like a hot tub.

Of course, 2011 patent law changes now make it irrelevant who invents or documents something first, as filing date is the only important factor anymore...making IP theft so very much more convienent and inexpensive.

The basic requirements for filtering, reheating and recycling the water and the heat are not difficult nor expensive:
1 pump rated 2.5gpm @ 12' head
1 filter rated at 5-10gpm (filter loaded)
1 5-10 gallon (2-5 minutes supply) holding tank
heater capable of raising the temperature of the water 5f at 2.5 gpm.
computerized temperature and turbidity sensors, temperature and flow controllers.

Excellent idea but a little expensive. Another great Australian water saving shower is the Cullector. It's an Ultra Efficient Shower that collects the initial volume of cold water before it exits the rose and then mixes the collected water back into the shower stream during the course of the shower. You may have seen it on the ABC New Inventors a few years back. It is a DIY, Retrofit and is self powered. Take a look at

There is the problem. I'm sure in time the price will go down, but people who could really use this are not going to get one for the longest time. I'm talking about Africa, in places with little potable water and drought could really use something like this. How sad.

$2700.00 not counting installation? Well, guess that's one great idea I won't be using....but the shower head I've got allows me to stem the flow while sudsing up and then push the button and the flow starts again for the rinse. It was $40.
