Australian-owned Nubian Water Systems has now gained accreditation in Western Australia for the introduction of its Oasis Domestic Greywater Treatment System (GT600).
Oasis Domestic Greywater Treatment System takes the greywater generated by baths, showers, laundry and hand basins and treats it to a high quality, suitable for safe garden irrigation using sprays or drippers. The Oasis Domestic Greywater Treatment System is a practical and affordable urban solution for garden owners and sustainable landscapers and architects.
One of the great benefits of the Oasis Domestic Greywater Treatment System is its capacity to deliver a reliable water supply for gardens in times of drought and tight water restrictions.
WA water restrictions allow just two days of watering in the Perth and southern region. This is stressing many plants and trees that require more water, especially in summer heat.
Oasis Domestic Greywater Treatment System now provides significant extra water for mature and sensitive plants. 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.
Gardeners who use recycled water should install smart irrigation systems that control volumes and intervals of flow rates to gardens, to extend the water availability to areas needing water.
The Oasis Domestic Greywater Treatment System is installed by trained and accredited plumbers to ensure compliance with plumbing and health regulations.
Nubian Water Systems finds Green Plumbers are aware of the advantages of installing systems that create sustainable gardens for environmentally responsible families.
Nubian Water Systems CEO Steve Makins says: “The Oasis Domestic Greywater Treatment System accreditation represents a welcome boost for Western Australian home owners coping with 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%. New home owners are able to design sustainable homes by separating greywater and recycling it.”
“This use of recycled water also substantially reduces load on municipal waste systems, which represents yet another important community cost-saving.”
Treatment systems accredited by Health departments demand high quality water through sophisticated processing, to ensure safety of consumers when used in above ground sprays and drippers.
Diversion systems do not treat greywater, so their water contains all the germs, pathogens and chemicals from showers and laundry – effectively dilute sewage, which can only be safely discharged below the surface.
Responsible parents would not want to expose their children to raw greywater that goes septic within 24 hours in storage containers or ponding in gardens. Oasis Domestic Greywater Treatment System removes that concern completely.
“We urge WA Water to offer greater rebates for purchasers of greywater recycling systems, currently only $500, when rainwater tank rebates can be $600. With the new accreditation usage allowing above ground irrigation, it shows the quality of water being much higher than untreated diversion systems that also attract $500 rebates.”
“We believe OASIS will save over 50% more water on average than rainwater tanks in a four person household in most existing houses due to awkward roof catchment configurations. It justifies a much higher rebate”
Makins says “The sleek, compact, above-ground design of the Oasis Domestic Greywater Treatment System is ideal for urban housing. No excavations are necessary. It looks great and can be up and running within days of installation, as the natural biological process establishes itself.”
Makins continues “An important ecological benefit of the Oasis Domestic Greywater Treatment System is that the treated greywater is discharged at PH 7.0, a neutral level which doesn’t effect soil fertility.
“The treatment process is chemical free so no chlorine or other chemicals, are added to the environment. The recycled water is disinfected to make it safe for human contact and allow its use for irrigation of general plants and fruit trees”
An additional benefit of the Oasis Domestic Greywater Treatment 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 Water Systems has estimated that if the 20.2 million people in Australia treated their greywater 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.
Makins says “The market in the eastern states has received the Oasis Domestic Greywater Treatment System launch with great enthusiasm and Nubian Water Systems has literally been flooded with enquiries and orders.”
New housing developers and renovators in particular are finding the Oasis Domestic Greywater Treatment System to be the ideal greywater recycling technology. Porter Davis Homes in Victoria, one of the state’s largest project home developers have selected Nubian Water Systems’ technology.
Oasis Domestic Greywater Treatment System treats the greywater 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 Oasis Domestic Greywater Treatment System has a collection water tank, a processor and a treated water tank where the recycled water is stored prior to reuse.
The Oasis Domestic Greywater Treatment System is accredited for use in NSW, Queensland, ACT & Victoria, SA and now WA. There are over 50 accredited installation agents.
Nubian Water Systems received Highly Commended status in 2007 from Engineers Australia for the Oasis Grey Water Recycling System.
