The image depicts two diagrams, one representing the current water supply system and the other representing the future water supply system. In the current system, water flows from a dam/storage to a water treatment plant, then to households, shops, factories, and a city, with pure water, storm water, and waste water being discharged into a river. The future system is similar but includes additional lines for storm water and waste water management. Both diagrams use arrows to indicate the direction of water flow, with three types of arrows representing pure water, storm water, and waste water.
Given the complexity of the image, the above description may not be entirely accurate.

The pictures depict how the water supply system changes in Australia from two different periods.
Overall, the main changes that are transparent are on the future plan are that pure water is also being produced from the waste treatment plant, and there is no water thrown into the river.
To commence, both plans include the distribution of pure water from the dam or storage to the residents, including households, shops, factories, and the city. However, the old plan divided the water that comes from the residents into two categories; the storm water is being transferred to the river, whereas the waste water is being processed through the water treatment plant.
On the other hand, the new plan did not add the river capacity, as both of storm and wastewater are being directed to the water treatment plant, which then neutralizes and produces pure water that could be used by the citizens again.
