The diagram shows how rainwater is collected for the use of drinking water in Australian town.
The diagram illustrates the process by which rainwater is collected and treated in an Australian town for domestic consumption. The process involves three main stages: collection, filtration and storage, and then purification for distribution as drinking water.
Initially, rainwater is captured from the rooftops of houses and directed into a drainage system via gutters. This water then passes through a series of pipes towards a filtering system. This stage is essential to remove any large debris or impurities from the water.
Following filtration, the rainwater is accumulated in a storage tank. At this point, the water remains unfit for consumption, necessitating further treatment to eliminate contaminants. Consequently, the stored water is piped to a water treatment plant where chemical purification occurs. Here, any remaining impurities are removed to render the water safe for drinking.
Finally, the purified water is pumped back through a network of pipes, supplying each house with potable water. The cyclical process thus ensures that rainwater is effectively harnessed and utilized for domestic uses.
