Innovative Grey Water Treatment System from Nubian
Australian-owned Nubian Water Systems has recently launched the Oasis Domestic Grey Water Treatment System (GT600). The Oasis is a practical and affordable urban solution, generating a saving of almost 400 litres of drinking water a day for the average four person household. Oasis takes the grey water generated by baths, showers, laundry and hand basins and treats it to a high quality suitable for garden irrigation, toilet flushing, clothes washing and car washing. 
One of the great benefits of the Oasis GT600 is its capacity to deliver a reliable water supply for gardens. Property owners can be assured of a water supply for maintaining their gardens which typically contribute 8% or more to the value of their property.
Nubian Water Systems CEO John Huggart says, “The Oasis GT600 Grey Water Treatment System summer launch represents a welcome boost for home owners coping with acute water restrictions for their gardens. Our system provides a regular, reliable source of high quality recycled water for garden use while typically reducing demand on precious town drinking water by 40%. This use of recycled water also substantially reduces load on municipal waste systems, which represents yet another important community cost-saving.”
“The sleek, compact, above-ground design of the Oasis GT600 is ideal for urban housing. No excavations are necessary. It looks great and can be up and running within 24 hours of delivery.
“An important ecological benefit of the Oasis GT600 is that the treated greywater is discharged at PH 7.0, a neutral level which doesn’t affect soil fertility. The treatment process is chemical free so no chlorine or other chemicals, which contribute to the depletion of the ozone layer, are added to the environment. The recycled water is disinfected to make it safe for human contact and allow its use for irrigation of fruit and vegetable gardens.”
An additional benefit of the grey water system is that it decreases the harmful effects of high levels of phosphorus to 3 mg/L which means at this concentration it acts as a natural fertiliser and is of great benefit to the garden.
Nubian have estimated that if the 20.2 million people in Australia treated their grey water and recycled it, there would be a saving of over 700,000 mega litres of drinking water, enough to supply the total annual drinking demands of Sydney and Melbourne. In addition, by using a chemical free process, there would be an annual reduction in chlorine of 3,500 tonnes.
Commenting on the launch Huggart adds, “The market has received the Oasis GT600 launch with great enthusiasm and Nubian have literally been flooded with enquiries and orders.” New housing developers and renovators in particular are finding the Nubian Oasis to be the ideal grey water recycling technology.
Oasis treats the grey water in a three steps process. The water is first screened to remove lint, hair and other particles. It then passes through media where contaminants are removed through absorption, biological process and filtration, and it is finally disinfected. The grey water treatment system has a collection water tank, a processor and a treated water tank where the recycled water is stored prior to reuse.
The Nubian Oasis GT600 is accredited for use in NSW, Queensland, ACT and Victoria and has over 40 accredited installation agents.
