The diagrams illustrate the water supply in Australia both in the present and future.
Overall, the plan for the future water supply system uses a recycling process.
Looking at the current water supply system, pure water is stored in the dam then transferred to households, factories, and shops in the city. Storm water is directed to the river from the city and waste water goes directly to the water treatment plant from both the city and the dam.
Moving on to the future water supply system, it is clear that the pure water stored in the dam will not change its route to the city. However, there are significant changes such as the waste and storm water being transmitted to the water treatment plant instead of the river. Finally, pure water will be recycled back into the city for day to day use. The future planning of the water supply system ensures that water won’t be secreted to the river.
