The given diagram depicts information regarding the artificial process of gathered and purified rainwater for the use of ready-to-use fresh water in an Australian town. Overall, this is a complex and linear process that entails six steps, initiating with the collecting rainwater and culminating with fresh water being used for household purposes.
Looking first at the initial three stages, the process begins when rainwater falls on the roof and then poured into a drain. After that, rainwater is pumped through the drain to go to the water filter to purify before being stored in the subsurface container. It is important to note that purifying plays a vital role in the process.
In the fourth step, purified water is dispatched into another storage where they handled one more time in the water treatment with chemicals to remove and release bacteria in the water. In the final stage, ready-to-use water is pumped through the pipe to every household in the town for drinking.
