Aussie Students Make Water Purifier from Chip Packets

Posted by Peter, on September 16, 2014

University of Adelaide engineering students have developed a simple water treatment system using foil chip packets and glass tubing, hoping they can save lives in the developing world. The device consists of half a cylinder of reflective material. All the light that hits that reflective material is directed at a glass tube, which is about […]  Continue reading »

New Desalination Process Uses 80% Less Energy

Posted by Peter, on June 28, 2014

A new cost-efficient and environmentally-friendly method of desalination for irrigation has been developed by a team at the UTS Centre for Technology in Water and Wastewater. Traditional methods of desalination rely on large-scale heating and evaporation processes or high pressure water pumps that force water through filtering systems. Dr Hokyong Shon and his colleagues at UTS […]  Continue reading »

Floating Solar Power Plant for South Australia

Posted by Peter, on May 12, 2014

Geits ANZ is proposing to build a solar power plant which would float on a wastewater treatment basin near Jamestown in mid-north South Australia. The system would be constructed from a high-density polyethylene pipe, which provides the buoyancy, with a structural steel pontoon sitting on that and PV panels slotted into the structure. The solar […]  Continue reading »

CSIRO Says More Water Reseach Needed

Posted by Peter, on July 26, 2013

The Federal Government's National Food Plan envisages Australia as becoming the food bowl for Asia. However, CSIRO scientists say that far greater investment in research into water efficiency is needed if this is to become possible. The British water expert, Professor Tony Allan, who created the concept of virtual water, said that ""Virtual water is […]  Continue reading »

Artesian Basin Found to Be More Extensive Than Thought

Posted by Peter, on July 20, 2013

Australia's Great Artesian Basin is one of the largest groundwater basins iin the world. Underlyng parts of Queensland, New South Wales, South Australia, and the Northern Territory, it contains 130,000 times as much water as Sydney Harbour. Previous research into how water flows through the basin and to the surface was 30-years-old. It was believed […]  Continue reading »

CSIRO to Assist in Asian Water Project

Posted by Peter, on July 12, 2013

Scientists from the CSIRO are applying their knowledge in transboundary river basin management to improve the livelihoods of people living in some of the poorest parts of Asia. The CSIRO scientists will provide technical assistance to the International Centre for Integrated Mountain Development’s Koshi Basin Programme in developing an integrated basin-wide modelling system to improve […]  Continue reading »

New Aussie Technology to Clean Polluted Water

Posted by Peter, on May 9, 2013

Scientists from Deakin University, together with French colleagues, say that they have manufactured a lightweight and reusable material that can absorb up to 33 times its weight in a wide range of spilt oils, chemical solvents and dyes, while repelling water. Deakin University's Dr Wei Wei Lei said that "The effective removal of oils, organic solvents […]  Continue reading »

Underground “Water Banking” Recommended

Posted by Peter, on December 11, 2012

A paper by Andrew Ross, a researcher at the National Centre for Groundwater Research and Training in Adelaide, recommends that Australia should prepare for dry times by ‘banking’ its water underground when rainfall is plentiful, Mr Ross says that water banking offers a way to "waterproof" Australia’s major urban centres. The known capacity of aquifers […]  Continue reading »

Using Seawater to Grow Crops in the Desert

Posted by Peter, on November 25, 2012

In 1991, Charlie Paton, a British lighting engineer and inventor established a company called Seawater Greenhouse with the idea of using only seawater and sunlight to grow crops in greenhouses. In 2010, Seawater Greenhouse build one of his greenhouses on arid land near Port Augusta in South Australia for another company, called Sundrop Farms. Sundrop […]  Continue reading »

CSIRO Rejects Coal Seam Gas Industry Claims

Posted by Peter, on September 5, 2012

THE CSIRO has rejected claims made by the coal seam gas industry in a television advertising campaign. The commercials, which were broadcast in Queensland on Sunday night, were produced for  the Australian Petroleum Production and Exploration Association. They stated that ”CSIRO (and government studies) have shown that groundwater is safe with coal seam gas.” The […]  Continue reading »

Desalination Using Waste Heat

Posted by Peter, on April 23, 2012

Scientists at Victoria University have shown the viability of a new desalination technology that uses almost no electricity and has the potential to save huge amounts of water. The membrane distillation technology uses waste heat to evaporate waste water through a fine membrane. The evaporated water condenses on the other side of the membrane as […]  Continue reading »

Australian Technology Cleans Up Nuclear Waste

Posted by Peter, on November 15, 2011

Queensland University of Technology researchers have developed new technology capable of removing radioactive material from contaminated water. The innovation could solve the problem of how to clean up millions of tonnes of water contaminated by dangerous radioactive material and safely store the concentrated waste as well as aiding clean-up efforts following nuclear disasters. The technology, […]  Continue reading »

Sydney Plans City-wide Recycled Water

Posted by Peter, on January 15, 2011

A consortium has been selected by the City of Sydney to develop a decentralised water master plan which would include Australia’s first city-wide recycled water network and significantly reduce demands on drinking water supplies. The recycled water network would connect to apartment, commercial and institutional buildings which are responsible for 80% of the water consumption […]  Continue reading »

Sydney Water Capture Plan

Posted by Peter, on July 21, 2010

The City of Sydney is seeking tenders to develop a Decentralised Water Master Plan aimed at producing more than 10% of the City’s water supply from local sources. Currently, the inner city imports drinking-standard water from Warragamba Dam, but only 20% of this is used for drinking, cooking and washing. 80% is used for purposes […]  Continue reading »

CSIRO Develops Greywater Testing Method

Posted by Peter, on January 18, 2009

The CSIRO’s Water for a Healthy Country Flagship and the Smart Water Fund have announced that they have developed a practical, robust, sustainable method for testing whether greywater treatment technologies meet Australian standards. Currently, there is no standard national testing method; states and territories each have their own legislation for greywater collection, treatment and use. […]  Continue reading »

Cloud Seeding Success in Snowy Mountains

Posted by Peter, on October 15, 2008

A big cloud seeding trial is being credited for a positive turn-around in lake levels in the New South Wales Snowy Mountains. For the first time in five years, water storages are rising after droughts that had seen lake levels fall to their lowest since the opening of the Hydro Electric Scheme in the 1950s. […]  Continue reading »

Adelaide to Harvest Stormwater
