The diagram illustrates how to recycle stormwater in an Australian city.
Overall, it can be easily seen that the process comprises five steps, beginning with collecting rainwater and ending at the distribution stage.
In the first stage, water is collected from the drain which was beneath the house, then flows through the tube to water recycling plants where the following four stages will be conducted. At the plant, some object waste such as plastic and rubbish are filtered out first and then small particles also be eliminated to ensure that water is purified and doesn’t have any bacteria and viruses. Finally, the plants get rid of unwanted molecules and salt. What is left over is treated with chlorine 4mg/l and put into safe water storage before pumping to households, ready to be used.
