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.

The diagram illustrates the way in which rainwater is collected and treated and

then

used as drinking

water

in a particular town in Australia. At the onset,

it is clear that

there are seven stages in the process, beginning with collecting rainwater and culminating in using it as drinking

water

.

To begin

, rainwater falls onto houses’ roofs and gathered in special reservoirs placed on the roofs. Each house collects

water

in

this

way. After that, the

water

goes through vertical pipes installed on the side of the houses and drops into drains at the bottom.

Following

this

, once enough liquid is collected, it runs to storage and

then

is filtered by

water

filters located under the ground from any solids.

Next,

cleaned

water

is put into storage and kept there for some time. In the subsequent stage, the

water

goes to reservoirs with added chemicals for

water

treatment to make it safe for drinking.

Finally

, ready

water

is distributed between houses and could be used as drinking

water

.
