Model Answer
The given pictures illustrate Australia’s current water supply system and the changes proposed to it in future. It can be seen that the changes proposed are for better recycling of water, and also the wastewater will not be released into the river.
At present, the city receives its supply of pure water from a dam. This pure water is supplied to households, factories and shops in the city. From the city, the storm water is released into the river. The wastewater generated by the city is sent to the water treatment plant. From the recycling plant, the treated waste water is sent to the river.
The future plan of the water supply system shows that the city will continue receiving its pure water supply from the dam. However, the storm water will not be released into the river. Instead, the storm water and waste water from the households, shops and factories will be sent to the water treatment plant. After the water is treated, pure water will be sent back to the city for use. There will not be any water released into the river.
Overall, Australia’s water supply system will be based on a better recycling process and the river will not have any water released into it.
