The provided picture demonstrates how to collect rainwater and treat for the purpose of drinking water in a town in Australia.
It is clear that the process of collecting rainwater for drinking consists of five main stages, starting with the collection of rainwater and ending with clean water to consume.
Looking at the diagram in detail, in the first step, the rainwater from the rooftops of houses goes along pipes to underneath drain systems. Next, the water passes through a water filter where impurities and solid substances are removed.
The process continues with the filtered water flowing along the pipes to a large tank to store. In the next step, the water is transferred to a water treatment before being treated by chemicals. Finally, the clean water goes from the water treatment to the faucets of houses.
