The diagram illustrates various stages in the process of water purification using rainwater harvesting in an Australian town. The water that is collected during the rainy season runs through three stages before reaching households as drinking water.
Firstly, all the rainwater trapped from different homes travels down the drain to the water filter where it is treated for impurities. It is further passed to the storage tank before travelling to the next stage. In the second stage of the process, the water is treated for other germs and bacteria left by adding some chemicals like chlorine to make it fit for drinking. In the last stage, the freshwater is supplied to households and can finally be used by people.
Rainwater harvesting is an economical way of using the rainwater that is collected in huge amounts in our houses and can be made fit for drinking with such an easy and short process as described in the diagram.
