collecting and treating rainwater in Australia
Topic: The diagram shows how rainwater is collected for the use of drinking water in an Australian town.
The diagram illustrates the process of collecting and treating rainwater so that it can be used as drinking water in households of a town in Australia.
Generally, rainwater is collected through a gutter and drain system. It is then filtered and treated using chemical and distributed to each household as drinking water through pipes.
Each house in the town has gutters installing to its roof. Those gutters are connected with pipes along the side of the house that brings water to the drain underneath. When it rains, rainwater from the roofs is collected into the gutters. It follows the gutters to the pipes and goes down to the drain below.
From the drain, water is brought through a filter to remove any impurities before going to a storage tank. Then, it runs along a pipe to the water treatment system. Here, chemicals are used to process rainwater and the output is drinkable water which is distributed to each household for consumption via another pipe system.
