Australia’s national science agency CSIRO (Commonwealth Scientific and Industrial Research Organization) scientists have vested bottled water with some respectability in brandishing a new product dubbed as Recharge. Though it’s also packaged water, the process it goes through makes it an allowable one. The researchers subjected storm water to natural treatment processes and engineering methods and finally they delivered pure water. It nowhere falls short of the drinking water health standards.
First, they stored the storm water somewhere beneath the city of Salisbury in South Australia in porous limestone aquifers. Since they wanted to keep it as pure as was possible, it was shrouded 160 meters below the ground level and later filtered it via a wetland. Further, it was passed through activated carbon fiber, then micro filtration, ultraviolet disinfection and ozone disinfection. CSIRO certifies it as perfectly potable containing no contaminants whatsoever.
