The diagram below demonstrates the process of collecting and reusing rainwater through several simple stages.
Overall, the process begins with collecting water in a dam or a tank and finishes with the release of excess treated water and stormwater treatment in a river.
In the first step, a dam is used to collect the water from the rain falls. Afterward, it moves to a water treatment facility to generate fresh water for drinking or household using. Furthermore, there is a rainwater tank beside the house to collect the rainwater that falls from the rooftops. For home use, rainwater from a tank may go through water filter to be cleaned.
Finally, the household wastewater iss processed in a wastewater treatment plant, the recyled water will be repurified and used for household purposes. Meanwhile, the rest of water will be discharged to the water flow nearby. Surface runoff water is a form of stormwater made it flow to the waterway nearby.
