What to know about the new state-of-the-art water treatment technology

An Australian study says the country’s water infrastructure is now up to 60 per cent more efficient than it was in the 1980s.

Key points:The study was commissioned by the NSW Water Services Authority (NSWWA) and looked at the latest water treatment technologiesThe study found the NSW water supply is 50 per cent less efficient than the 80s and 80sWater systems are more efficient because they are more sophisticatedThe NSW water system is at 60 per year, but the study said the state’s system is now 10 times as efficientAs a result, NSW has seen an average reduction in water use of up to 45 per cent over the past 20 years, said the study, which was commissioned for NSWWA by the Australian Water Technology Association (AWTA).

“Water is the single largest water resource on our planet, it is essential to our economy, our way of life and our health,” NSW Water Minister David Heffernan said.

“We need to get on top of this, and we need to do it right.”

Key pointsThe study used data from the Australian National Water Survey (ANWS) and the Australian Hydrological Unit (AHU) to estimate the total cost of the water supply over the last 40 years.

The study also looked at other factors such as how much water a city uses and how much energy it uses.

The NSW Water Authority commissioned the study as part of a research project into water efficiency.

The AWTA said the NSW government’s Water Services Act 2012 included a provision allowing the state to build a water treatment plant at a cost of $5.2 billion.

This would provide an extra 5,000 megawatts of water to the state over 30 years.

“This is a huge deal for the region and for the nation,” NSWWA Chief Executive Michael Pacheco said.

The government estimates the cost to build the new plant at $4.5 billion.

“The investment will allow the state government to build an 80-metre high, 50-metres deep, 50,000-square-metrel capacity water treatment and treatment plant that will reduce the cost of water supply by more than $6 billion over 20 years,” Mr Pachecco said, adding the plant would not only reduce the amount of water used, but would also increase the efficiency of the system.

“It will also increase water use and improve water quality in our region,” he said.

Water treatment technologyThe AWTAs report also examined the latest technologies in the water treatment industry, including the new Kinetico technology, which is being introduced in NSW.

“Kinetico is the most efficient water treatment in the world, with a 95 per cent efficiency rate,” Mr Hefferen said.

It is being tested in Queensland and Victoria, and is due to be rolled out nationally next year.

“That means NSW is now in the top 20 water treatment facilities globally,” Mr Herven said.

In a statement, Mr Hefernan praised the research and said the new water treatment equipment was expected to save the state $1.4 billion a year in water bills.

“By providing a superior system to ensure water is treated, the system reduces water usage and the amount that is used,” Mr he said, saying it would also reduce water quality.

“Water will be cheaper and we can save water.”
