The given diagram illustrates the information about the steps that are involved in the process of water supply in present and future in the country of Australia.
Overall, there are essentially four levels in the water supply steps, beginning with the water storage and ending with stormwater transfer to the river.
In the present water supply, in the first stage, water is stored in a dam and is transferred to different places, and there are three different types of water, pure, strom, and waste. secondly, the stored water sends water to the households, the factories, the shops, and the city in the form of pure water. following this, wastewater is transferred to water treatment plants from dams and industries, complexes, towns, and the waste from houses. Next, the stormwater directly flows to the river from big cities, industrial usage, shops, and by household works.
In the future, the water supply system will be have same as the present water supply system but stormwater will flow to water treatment, and it will be reused as clean water by users.
