The diagram illustrates the construction and the function of a basic water filter in producing drinkable water.
Overall, there are three main stages in this process starting with pouring impure water into the filter and ending with clean water stored in tank. This process includes man-made works and system works
Initially, impure water is poured into the filter tank, which contained three layers of filters: sand, charcoal, gravel. Once the water completely stayed inside this tank, it is gradually go through each filter layer. When the filtered water reaches the last layer, it is completely clarified.
In the following step, clean water is transmited to the clean water storage area through a pipe or a hose which links from the bottom of the filter system to the storage bines. Finally, these bines are delivered to the customers
