The diagram illustrates how to convert rainwater into the water for drinking in an Australian town. Overall, this is a simple and linear process with two main stages, including: collecting water period, and processing ones. Moreover, it also can be seen that there are five steps to create the drinking water from rainwater.
Initially, when it rains, the rainwater drops onto the roof, followed by flowing into a drain. Next, the water is put in a water filter, where it is purified to remove any excess dirt. Then, the water is injected into a pipe to transport to a cistern, which is used to store water before it takes part in a treatment stage.
In the following steps, the water flows into another container to treat with chemicals, which helps eliminate thoroughly contaminants in water. Finally, fresh water is pumped through a pipe that flows from treatment tanks to the household taps for consumption.
