The diagram depicts the recycling process of storm water in a city in Australia.
Overall, there are 5 distinct steps to transfer natural water stemming from rains and storms into domestic one. This process begins with storing storm water, and ends with distributing recycled water for using purpose.
Initially, water falling into natural phenomena such as rains and storms is collected through available drainage system under the ground. Following that, non-processed water officially experiences sorting period within 4 levels to release dust and other harmful ingredients. Those consists of plastic rubbish, small particles, bacteria and viruses, and molecules and salt, respectively.
At the third stage, water is then mixed with a small proportion of chlorine (only takes up 4 mg/l) to become cleaner and more crystal. After that, recycled water is transported to chambers for storage before reusing for domestic aims via underground waterpipe system.
