The provided diagram illustrates the stormwater treatment process in an Australian city. Overall, the entire process consists of several stages, beginning with the collection of rainwater through drains during rainy weather, and ending with the supply of recycled water to households during sunny days. Additionally, most stages involve purifying and cleaning the water. To begin with, during rainfall, the stormwater is collected through drains, after which it is channeled to the water recycling plant through pipes. During this stage, the water passes through a treatment process comprising four small stages with varying extents of removal, where impurities such as plastic, rubbish, small particles, bacteria, viruses, molecules, and salt are separated from stormwater. After this stage is complete, the purified water is then cleaned by adding chlorine at a concentration of 4 mg/l, after which it is transferred to the water tank. Ultimately, the processed water is supplied to city households for domestic use.
