The diagram shows how rainwater is collected and turned into drinking water in a town in Australia.
Overall, rainwater goes through several steps before it is safe to drink. It is collected from rooftops, filtered, stored, treated with chemicals, and then sent to people’s homes.
In the first stage, rainwater falls on the roofs of houses and is collected through a system of gutters and pipes. After that, the water flows through a filter, which removes leaves, dirt, and other unwanted substances.
The filtered water is then stored in a large tank. From there, it is sent to a water treatment system. At this stage, chemicals are added to kill any germs or bacteria that could be harmful.
In the final stage, the clean water is pumped through underground pipes and delivered to homes, where it can be used as drinking water.
