The diagram depicts the process of recycling rainwater to make it suitable for human use, beginning with the collection of rainwater and ending with the discharge of excess treated water into rivers.
Overall, the diagram illustrates a cyclical process in which rainwater is collected, stored, and used in households before being treated and recycled. While some of the water is reused for domestic purposes, excess treated water is released into natural sources.
The process begins with rainwater being collected from the roof and stored in a rainwater tank for later use, such as washing and sanitation.
Another source of water supplied to the house is drinking water, which is provided from a water treatment plant. After use, household water becomes wastewater and is sent to a wastewater treatment plant, where it is treated and separated. Some of this water is then recycled back into the house, while the remaining water is discharged into the environment. In addition, excess rainwater, known as stormwater, undergoes treatment before flowing into nearby rivers.
