The diagram illustrates the process of harvesting rainwater for drinking purposes in an Australian town.
Overall, the process involves six stages, beginning with the collection of rainwater from rooftops and ending with its distribution as treated drinking water to the town’s residents.
The process starts with rainwater being collected from the rooftops of houses. The water then flows through a system of connected drain pipes and is directed to a water filter, where impurities and debris are removed. After filtration, the clean water is transported via pipes to a large storage tank, where it is held until further treatment.
The stored water is later transferred to a treatment tank, where it undergoes a purification process using chemicals to make it safe for human consumption. Finally, the treated water is pumped through another set of pipes that connect to individual houses, allowing residents to access potable water directly from their faucets.
