The given diagrams illustrate the current and projected future water supply system in Australia.
Overall, the present water supply system includes specific water types which are sourced from a dam/storage facilities, treated at water treatment plants, and distributed to various sectors. With regards to the future project, it is forecasted that stored water will not be treated by plants, but these facilities will substantially reduce the waste which accumulates in the river by cleaning stormwater.
In the current scheme, pure water obtained by the dams or storages is channelled to the people’s necessities, such as households, shops, and factories. From there waste water caused by human activities is funnelled to the water treatment plants for processing. In addition, storm water is directly sent to the downstream river directly from the city.
Looking at the predicted project of water deliveries, it will incorporate the same delivery of stored water to these sectors and then to water plants for cleansing. However, in contrast to the current plan, the processed wastewater will be redirected to the households, shops, and factories that will significantly save the amount of clean water. Another noticeable change is that the treatment facilities will additionally purify the storm water that is now pouring out to the river.
