The give diagram illustrates the process in which rainwater is recycled in a city in Australia.
It is apparently ready that there are five stages in the process of recycling storm water. It starts when rainwater is collected by a drainage system and ends when water in storage is flowed into house.
Looking at the detail, initially water falling down onto rooftop is collected via a series of drains before leading to water recycling plant to clean up storm water. At this step, plastic, rubbish; small particles; bacteria viruses and molecules, salt are gradually filtered out from rainwater.
In the second half of the process, the water is pumped into a tank where chlorine 4m/l is added to purify the water. Subsequently, filtered water is transported by pipe to a second tank for storage prior using. In the last step of the process, the water is piped into back house to be used during sunny weather.
