Model Answer
The diagram depicts how rainwater is harvested, treated, and stored for the purpose of drinking water.
Overall, there are five key stages in the process of harvesting rainwater for drinking, beginning with the capture of water when it rains, and ending with clean drinking water available inside people’s homes.
Firstly, when it rains, water is captured on the roofs of people’s homes. The water runs down the roof and into the gutters, where it then flows into drainage pipes attached to the side of the houses. All drainage pipes from the houses flow into one larger system, from where the water is then run through a water filter. Once the water is filtered, it then flows into large storage tanks where it is held until a later time.
From the storage tanks, the water is transferred to a treatment tank where chemicals are added to it. The water is then ready to be delivered via pipes that flow from the treatment tanks to the taps inside people’s homes.
