The diagram visually depicts the recycling process of storm water in a particular urban area in Australia.
Overall, what stands from the picture is that there are five main stages, beginning with rain water collection, followed by water treatment and ending with the distribution of water to a residential house in sunny weather.
Initially, after storm water dropped into the land, it is then collected with a system of drain pipes, leading to a water recycling plant in which some elements are eliminated from water. Particularly, rain water is processed via four steps, including removing plastic litter and rubbish, small particles, harmful bacteria and viruses, and finally molecules and salt.
At the next stage of this man-made process, recycled water is subsequently transported to a water tank before adding chlorine to purify untreated water, while impurities are being taken away. Having been finished the treatment phase, potable water is tranferred to a water storage in order to provide clean water for usage in dry climate.
