The diagram below illustrates how stormwater is recycled in an Australian city.
Overall, rainwater is collected and undergoes to a recycling process before being used, but before being used water will be treated with chlorine and then will be usable.
Rainwater is collected and sent to a recycling plant, which is divided into four stages. In the first stage, plastic and rubbish are separated from water. In the second and third stages, bacteria, viruses and small particles are removed from water. In the last stage, molecules and salt are removed from water.
Finally, Chlorine is added to disenfect the water, and four mg of chlore is added to water per one litr, and the last stage is a water storage. Now, collected water which is cleaned now avaiable for future use.
