Australia is applying new technology to treat wastewater.

Perth, the capital of Western Australia, has been at the forefront of bringing treated wastewater into daily use, with an estimated volume accounting for about 20% of the total water supply for the entire region.

The decision was made after the local government announced the success of a three-year trial program of new technology.

The new technology has been tested at the Beenyup water treatment plant in the northern part of the city. All 62,300 water samples taken during the trial met all stringent health and environmental standards.

Western Australia's Water Minister, Terry Redman, said that Perth residents will be supplied with 7 billion cubic meters of water annually under the new water program, ensuring a stable supply in the future.

Perth's wastewater treatment program encompasses multiple stages, from collecting and storing the initial treated wastewater to further purification and disinfection using methods such as ultraviolet light, resulting in a final product of potable water.

This clean water is then pumped directly into the groundwater aquifer and, after several decades, will naturally rise to the surface for people to use through regular taps thanks to the city-wide supply system.

This treatment process ensures that wastewater is truly clean before being pumped into groundwater for naturalization, which can take approximately 30 years.

The success of the new technology is a step toward Perth's goal of having no water shortages.

Mr. Redman emphasized: "Adding groundwater will help ensure water security for Perth during periods of low rainfall. This also provides a new water supply option for the city, contributing to diversification towards the future and supporting other measures such as seawater desalination."
