The diagram presents how Australian towns preserve rainwater and supply it for drinking.
Overall, it can be clearly seen that this diagram supplies pure drinking water to every house from rainwater by using seven steps.
Initially, the rain naturally falls on the rooftop and is collected by the canal at the bottom of the house and runs to a dirt underground drain, which passes the water through a drain system around the house and through a water filter for purifying the germs, dirt, and impurities.
After purifying the water, it moves forward to a storage system; when storage is full, the water runs to water treatment by pipeline, which is attached to chemicals. The chemicals are mixed with the water for more purity and better quality. Then, the water transfers from water treatment to the drinking water step as pure drinking water. Now, it is ready for drinking and, finally, it is supplied to each and every house in all Australian towns.
