The picture illustrates how drinking water in an Australian town is used from the collected rainwater. Overall, it has 5 different stages from the rainwater collected to the drain, water filter, storage, water treatment, and finally rainwater become a drinking able water.
To begin, rainwater will fall on many rooftops and collected to the drain that connected each other. Water will flow to the water filter, which is a device used to filter water from large germs. The product from water filter, will go to the storage, a temporary storage place before the water will get to the water treatment.
Furthermore, water from the storage will flow to the next step, which is water treatment. In the process of water treatment, there are some specific chemical reactions that has the purpose for sterilizing the water and also make it possible to drink by killing some micro germs that left. After all stages are completed, the rainwater now can be used for healthy drinking water.
