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 figure illustrates the process used in a little city in Australia to create drinking

water

from rain.

Overall

, it is not a complicated process, in fact, it is formed by only six stages.

This

linear process technically begins when there are atmospheric precipitations, though it can continue to loop indefinitely every time it rains.

To begin

with, the saving procedure starts on the house’s roof, from which all the raindrops fall into the drain placed under the structure. Later the rain arrives at the

water

filter where it is cleaned and

then

passes to the next phase, the storage, in which the

water

is collected before the treatment. At

this

point, the

water

is ready to be filtered one more time with the addition of some chemicals that make it drinkable.

Finally

, in the

last

phase, every person in the town can enjoy the

water

from the tap of their house.
