The diagram below illustrates how a simple water filter is constructed and how it functions to produce clean drinking water.

The diagram shows the process involved in the construction of a

water

filter

and how clean

water

is obtained for human consumption. The

filter

is made up of a plastic barrel covered by a lid which is elevated above ground by some parts.

This

filter

is connected to a drum by a tube to a storage that contains the clean

water

. Inside
