Australia applies new technology to treat wastewater

Perth, the capital of Western Australia, has been leading the way in delivering daily treated wastewater, with an estimated volume of about 20% of the total water supply for the entire region.

The decision came after the local government announced the success of the new technology pilot program lasting three years.

New technology has been developed at the Beenyup Water Treatment Plant in the northern part of the city. All 62,300 water samples taken during the test meet all stringent health and environmental standards.

Ministers in charge of water issues of Western Australia, said Terry Redman said people in Perth will provide 7 billion m ³ of water per year under the new water supply program, to ensure a stable supply in the future.

Perth's wastewater treatment program consists of a number of steps, from the collection and storage of treated wastewater to the purification stages, by means of ultraviolet The final product is water that can be taken directly.

The clean water is then pumped directly into the aquifer and, after a few decades, will be pushed naturally onto the surface for use by ordinary water faucets thanks to the supply system throughout the city.

This process ensures that the wastewater is actually cleaned up before being injected into the groundwater to be naturalized, which can take up to 30 years.

The success of the new technology is a step towards the goal of no shortage in Perth's water supply.

"The addition of groundwater will help ensure Perth's water security in less rain," said Redman . "This is also a new water supply option for the city, contributing to diversification towards It also supports other measures such as sea water desalination. "
