The diagram shows how rainwater is collected for the use of drinking water in an Australian town.

The graph below illustrates a system's purpose to collect rainwater for the use of drinking

water

in a particular Australian town.

Overall

, the system is not complex at all, there are five key stages in the process of harvesting

water

for drinking, but it needs to ensure that the

water

is clear enough for humans to drink. First of all, the drainages pipes attached beside the house gathered the rainwater that stays on the eaves, after that all the drain pipes flow into one larger container, from where the

water

goes through the

water

filter.

Moreover

, it

then

flows into a larger storage tank where it is held to control the flow rate.

Nevertheless

, the

water

flows to the

water

treatment tank where the chemical is added to it. The

water

is

then

ready to be delivered via pipes that flow from the treatment tanks to the taps inside people’s homes.
