The diagrams illustrate the current water supply system in Australia as well as the projected system for the future.
Overall, the present water supply system includes water being sourced from dam/storage facilities, treated at water treatment plants, and then distributed to various sectors. There are three main types of water outputs: pure water, stormwater, and wastewater, all of which ultimately flow into a river. The future system is not specifically mentioned in the image.
In the current system, pure water is obtained from dams and distributed to fulfill the daily needs of the city, including households, shops, and factories. Wastewater, a direct result of human activities, is directed to water treatment plants for processing. Additionally, stormwater is channeled to the downstream river directly from the city.
The diagram does not provide details on the future water supply system in Australia, hence, no further analysis can be made based on the given image
