The diagram below describes how storm water is recycled in an Australian city.

The diagram below describes how storm water is recycled in an Australian city. OVVr7

The figure illustrates a recycling process of stormwater in an unspecified Australian city. From a general perspective, the process of recycled stormwater involves 4 principal steps initiating stormwater harvesting on rainy days, and ending with decontaminated reused water on sunny days. At the beginning stage, rainwater which is collected via drainage systems around the house flows in pipes to a 4-step underground water recycling plant. At the first phase of the water treatment plant, large wastes such as plastic and rubbish are discarded, then small particles are filtered out in the second phase. After that, microscopic impurities such as bacteria and viruses, and salt are removed in the third and fourth phases. Before the recommencement of the process, purified water is disinfected with chlorinating at 4 mg/l, after which it is stored in a chamber. The process ends when the water, now is safe for domestic use, travels along pipes that lead back into Australian households and reused on sunny days.
