The diagram depicts the process by which drinking water is produced from rainwater in an Australian town.
Overall, it is evident that this is a linear man-made process which consists of five main stages. The process begins with the collecting stage and culminates in fresh water being redistributed to households.
At the initial stage, rainwater is collected from the roofs of houses and is directed into a drainage system. Then, the water from all buildings is funneled through underground pipes. After being funneled, the water is sent to a water filter, where it is cleaned by having debris and other impurities removed.
After passing through the filtration process, the water is transferred to a storage tank. In the next phrase, the stored water is pumped into a treatment facility, where chemicals are added to ensure it is safe for consumption. Once the water is treated, it is sent back through a different set of pipes.
In the final stage, the purified drinking water is delivered to households for domestic use, having undergone a series of physical and chemical procedures that render it potable.
