The diagram illustrates how Australian collects rainwater for consumption after some processes. The step by step method as seen in the diagram has been used and still on, in the Australia to generate drinking water during the rainy season.
From the illustrated diagram it can seen that the rainwater after coming down from the roof of the house, it’s been channelled through the pipe beside the building directly for filtration to eliminate clumps and other particles, to be stored in on a large container.
The stored rainwater that has undergone filterstion processes will further be treated with a chemical may be Chlorine to keep it safe from germs and other micro organism that might be present. After then, the Chlorinated rainwater is been distributed to Australians for drinking and for daily consumption.
