The diagram illustrates the reusing process of stormwater in a city in Australia.
Overall, there are five stages in the process of recycling rainwater, beginning with the collection of the rainwater and ending with pumping clean water that was recycled into households for use.
Firstly, collecting stormwater, which flows from the pipes to the main pipe located underground. Next, water is led to the plant for treatment and eliminating the unnecessary here through a four-step process. Big things like plastic and trash are removed first. Then, filtering small particles and bacteria, viruses are eliminated to ensure water quality. Furthermore, getting rid of unwanted molecules and salt.
Accordingly, the remaining water is treated with chlorine to ensure safety when using it and 4 mg of chlorine per liter of water. Next, treated water is stored in water storage. Finally, recycled rainwater is pumped into houses when water is needed for daily life.
