The given diagram depicts the construction of a drinking filter and the functions of the production of clean drinking

water

. In ,general it is evident that there are many steps involved in

this

procedure Looking from an

overall

perspective, it is readly apparent that to clean drinking

water

, there are three ingredients that must be added sand,charcoal and gravel. Looking at the diagram, it can seen that the

water

filter constrection

firstly

, needs a drum and after adding gravel in the bottom of the drum and next the charcoal and sand.

However

, in the upper of the drum add the

water

,

In addition

, we can observe that the procedure begins time

water

passes through a thin tube to another drink drum and continues the procedure

Finally

the storage drum will get clean

water

and drinking

water

.
