The diagram below shows how rainwater 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 illustration presents an overview of the key

stage

involved in the collection of rainwater and the manufacturing of rainwater in an Australian town.

Overall

there are three main steps namely preparation, processing and using

water

treatment. The whole process of

water

production starts when it rains, the

water

from the people’s house flows down the same drain before undergoing a filter machine.

After

this

, the rainwater is filtered in order to remove any impurities, followed by being passed into a container through a tube which is positioned at the top of the container. In the next step, the filtered

water

through a tube which is located at the left bottom of the container is connected to a treatment tank. In

this

stage

, the

water

is added with any chemicals with a view to be transformed chemically before moving to the final step.

Subsequently

, a penultimate

stage

which is delivering

water

treatment via a pipe is carried out. It

then

leads to the final

stage

of the processing where the

water

is used in other houses.
