Posted February 23, 2019 08:11:17A new study has found that reducing CO 2 emissions through the adoption of efficient, energy-efficient water treatment techniques could reduce water consumption and water use by a factor of 10.
This is the first report to directly quantify the impact of reducing water use and CO 2 emission by using efficient water treatment technologies to achieve water conservation goals.
Lead researcher Dr Andrew McKeown from the University of Western Australia’s School of Environment and Sustainable Energy said water treatment had been overlooked for a long time because it was often assumed that it was not an important part of water management.
“We’ve done this in the water treatment sector and we’ve looked at a range of approaches including desalination and membrane treatment, and we found that water treatment has a major impact on water supply, especially with respect to reducing water demand,” Dr McKeone said.
“It’s a key component of our water supply management strategy and the water we consume in Australia is a significant contributor to our water demand and water resources.”
Water is a major water resource and it is important that we manage that resource to make sure that it’s being used wisely.
“Dr McKeon said the study showed that the benefits of water treatment outweighed the costs.”
The benefit of using water treatment is a big reason why we need to reduce water use in Australia,” he said.
Dr McVeigh said the water system was a key part of the water management strategy, and the results showed that water use was being reduced through water treatment in the country.”
In the water systems, we’ve shown that the water use is significantly reduced through efficiency and reduced by more than 10 per cent, which is quite a significant improvement over what was previously thought,” he explained.”
But what is interesting is that water used to be more than 20 per cent of water supply in some parts of the country, and it’s now lower than that.
“If we’re looking at the impact on our water resources, this is a huge improvement, and a significant factor of our ability to reduce our water use.”
The researchers from the Water and Climate Program at the University’s School are currently studying water demand trends across Australia and the region.
Dr MacKeown said he hoped the results would be replicated in other water systems around the world.
“Our findings show that water is being managed more effectively than previously thought, so if there are other systems around Australia that are doing similar things, it will provide more value to people and their water use,” he noted.
“As the world becomes more efficient, water use will continue to fall and water demand will continue down as a result.”
