The diagram illustrates the process by which rainwater is collected to be used for drinking in a town in Australia.
Overall, rainwater is collected from houses' roofs and passes through a drain, a water filter, a storage unit and a treatment tank before being distributed to houses for drinking purposes. Most steps of this process happen underground, and many pipes are used as pathways for the water to be moved to the next step.
While raining, all rainwater that falls on four houses' roofs is drained to pipes underground. After passing though several pipelines, the water goes to the water filter, which filters the water and then directs it to another pipeline. The water passes to a large tank where water is stored before being passed to another big tank where water treatment takes place. Next, certain chemicals are used to clean the rainwater. The resulting ready-for-drinking water is pumped to houses' taps where it can be drunk.
