The diagram shows how rainwater is collected for the use of drinking water in an Australian town. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram presents the process of producing drinking

water

from gathering rainwater in a town in Australia.

Overall

,

water

is processed through three main steps from the filter to the chemical treatment to serve consumers.

Firstly

, when it rains, each house collects rainwater from its roof and goes through gutters, eventually running into drains at the bottom of the house.

Then

the installed one large pipe underneath of houses gathers

water

from four houses and sends

water

through a filter to remove physical, biological and chemical contaminations from various causes

as a result

of making purified

water

.

Secondly

, after the process of

water

filtration from households, filtered

water

is kept in a large industrial size of storage tank to move on to the next final step. The

last

procedure is

water

treatment which is so-called sanitization to produce safe drinkable

water

for the public. In fact, the

water

storage tank and the treatment tank are connected with one duct and a couple of factories are built it on, eventually,

water

is treated by releasing chemicals from an upper building and carried away to houses in a town.

Finally

, rainwater is used without any adverse events.
