Writing Task 1 - Sample 5: Process (Band 7)

The diagram reveals a long process in which rainwater is contained, treated
and reused for domestic purposes.


The process starts with rains brought by clouds which provide water for natural
lakes, pools or artificial reservoirs likes dams. At the same time, rain water is
collected into tanks from gutters, then is used directly by people without any
treatment. Water in dams, however, must be filtered and made clean at water
treatment plants to become drinking water before being delivered to people’s
homes for daily usage.
The next step is treating waste water, the output of domestic consumption. This
type of water is collected from people’s houses to waste water treatment plant,
where it is turned to recycled water and flowed back to houses, while the excess
treated water is released to river. Also, any storm water must be passed through the
storm water treatment before running to its clean, natural state.
To conclude, the diagram may well reflect the steps by which rainwater is reused.
With two steps of treatment applied, water is made clean before being provided to
people’s usage and released to natural environment.
