The given diagram illustrates the construction and functioning of a basic water filter system aimed at producing potable water.

The water filtration system comprises two drums, layers of sand, charcoal, and gravel, and a pipe for transferring water. The first drum, filled with the mentioned materials, acts as a filter to purify water, while the second drum serves as a storage unit for the clean water.

The initial stage involves pouring contaminated water into the first drum, followed by its filtration through the layers of sand, charcoal, and gravel. This process progressively eliminates impurities as the water passes through each layer. As a result, purified water flows through the pipe into the second drum.

In contrast to the filtration drum, the second drum is devoid of any filtration materials and solely functions to store the clean drinking water. An additional feature of the second drum is a tap attached to its bottom exterior for convenient access to the purified water.
