The illustration depicts different steps through which rainwater is collected, processed and released for reuse for domestic consumptions. Overall, rainwater recycling process involves various interrelated phases including the use of the dam, treatment plant, water tank and the whole process is dependent on rain pour.
When the rain pours down to earth, a dam is used to collect rainwater and this water is then sent to a water treatment plant in order to produce drinking water. This water is then released for household consumptions. The houses have their own rainwater tanks which are placed adjacent to them and used for storing rainwater running from the roofs. Rainwater stored in tanks is used for domestic purposes as well. Household wastewater is then sent to a wastewater treatment plant for the recycling purpose from where the excess treated water is released into the river and the rectified water is drawn back to be used for domestic purposes again. In the interim, surface runoff water in the form of stormwater is preserved and made to flow directly into waterways nearby.
