TASK 1:
Question: The following diagram shows how rainwater is reused for domestic purposes.
ANSWER:
The diagram illustrates the process of reusing rainwater for household uses. Overall, there are 2 simultaneous processes, namely rainwater collection for domestic use and wastewater treatment for reuse or discharge.
There are two methods of rainwater collection for household consumption. In the first process, rainwater accumulates in a dam, which functions as a storage reservoir. It is then conveyed to a treatment plant, where impurities are removed to produce drinkable water, which is subsequently distributed to households. In addition, a tank is placed beside homes to capture rainwater directly from rooftops, serving as a supplementary source for domestic consumption.
The remaining steps focus on the treatment of wastewater. Used water from households is delivered to a treatment facility, after which the processed water flows back to households for reuse, whereas the excess treated water is discharged directly into a nearby river. Finally, stormwater, resulting from surface runoff during rainfall, is treated before being channeled into the same river. (168 words)
