The diagrams illustrate the present and future water supply systems in Australia.
Overall, the present water supply system sends pure water from Dam to households, shops, factories and city, then it is transformed into storm water and waste water which is sent to river and water treatment plant respectively. Whereas, in the future system, Storm water and waste water are sent to the water treatment plant and it converts them into pure water and sends it back to the city.
On the one hand, the system begins with a collection of water in the dam on storage. Then, the pure water is sent to the city where households, shops and factories use it. As a result, the pure water is now waste water and. Storm water. The water treatment plant receives the waste water and directs the water into the river after the use. Whereas, Storm water directly goes into the river.
On the other hand, future system is quite similar in the initial parts, not until the storm and waste water is forwarded to the water treatment plant rather than the river. The plant plays the vital role of converting the used water into water again after filtering it. Lastly, the Pure water is distributed to the city for normal useage.
