The new Perpetual Water system turns grey water blue
A new grey water treatment system can turn up to 750 litres of grey water into safe, high-quality, clear water daily, which should be enough to ‘drought proof your property’ and turn water normally discarded into a ‘renewable resource’.
The Farmers’ Info e-newsletter reports that ACT innovators Perpetual Water, who have earned nation-wide recognition for a unique domestic water recycling system, have been awarded a $720,000 Australian Government grant to apply the technology to residential apartment buildings.
The system has been subject to extensive government review and testing and has already won several innovation awards. It was featured on ABC TV’s New Inventors Program in late July.
How it works
Perpetual Water is a fully automated, simple-to-use system that runs silently outside of the house. A specially designed computer operates with the flick of a switch and doesn’t require any special attention. It uses minimum power and only needs to be serviced once a year by a technician.
The system has 11 sensors to ensure the system operates effectively and if a problem is detected the system automatically turns itself off. It also comes with safety taps and separate pipes to ensure treated water is never mixed with drinking water.
1. Grey water from the shower, bath, sink and washing machine is collected in a sump tank, buried underground, which removes hair, lint and other physical contaminants.
2. The water is pumped to a settling tank.
3. The water is pumped through Perpetual Water’s patented Active Adsorption Filtration™ system, producing water that looks and smells like tap water.
4. The safe, clean water can be stored in a reuse tank ready for perpetual household use.
Unlike other grey water systems, Perpetual Water can be used over the long term without causing health and environmental risks. It is safe to use for:
Not safe use
Even though the water is Class A and looks and smells like clean tap water, it is recycled and BY LAW must NOT be used for:
Can anyone give us a firsthand report on the system?
