You should spend about 20 minutes on this task. The diagram below shows how rain water is collected and then treated to be used as drinking water in an Australian town. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The diagram describes the process of collecting rainwater from houses and how it is treated to make it potable, in an Australian town.

Overall

, the process has five stages. It begins with the collection of impure rainwater from house roofs and ends with the transportation of safe drinking

water

into the same houses.

To begin

with, whenever it rains, the

water

is collected into a drain from each house. All the drains are connected to a bigger pipeline. The pipeline transfers all the collected impure

water

into a small

water

filter.

This

is where the

water

is filtered for the first time. After that, it is moved to a large storage tank.

Following

this

, the filtered

water

is sent to another large tank where.

This

is where the

water

is treated

further

.

Subsequently

, after reaching an almost full level, it is mixed with some chemicals. The

water

is now purified and is now pumped to the respective houses through a separate drain.

Finally

, drinking

water

is now accessible through

water

taps to be used.
