The diagram illustrates the stages involved in collecting rainwater for use as drinking water in an Australian town.
Overall, there are three main stages in the process, starting with the collection of rainwater, filtering, and finalization with water treatment before ready to be used.
Initially, the process commences with directing the rainwaters on the rooftops through drains in each household to the underground tubes, once it rains. After that, the rainwater coming from the tubes undergoes a process where it is filtered. Subsequently, the filtered water is sent to a huge water storage.
Afterwards, the water from the storage will go to another similar sized storage, known as water treatment, where it is treated with some chemicals to make it more usable. The water is then sent to the public for drinking use.
