Model Answer
The given diagram illustrates how rainwater is harvested to use as drinking water in an Australian town. A quick glance at the diagram makes it clear that rainwater is filtered and also treated chemically before sending it back to the houses for use by the people.
Initially, every house collects rainwater and sends it through drains to a water filter, where the water is first filtered to remove the impurities. After that the water is sent to a storage tank. From this point onwards, the water is sent to a treatment plant, in which chemicals are added to treat the water. After the chemical treatment the water becomes germ free. This potable water is then sent to the houses for consumption by people.
Overall, it can be seen that rain water is not wasted and successfully made fit for drinking in a very simple yet effective way by the residents of the Australian town.
