The diagram illustrates a straightforward mechanism for converting contaminated water into clean drinking water through the use of a basic water-filter assembly.
The system comprises two storage drums for filtering and storing water. It involves pouring unclean water, filtering through gravel, charcoal, and sand, and finally storing the purified water in a lower drum with a tap for consumption.
Initially, unpurified water is poured into an upper plastic drum after the removal of the lid. The water then percolates through three filtration layers: sand, charcoal, and gravel. Subsequently, a pipe system directs the clean water to the lower storage drum.
In the later stages, the filtered water is contained in the lower drum under a sealed lid, and a tap is present for drawing the purified drinking water. Overall, the process involves straightforward steps from filtration to storage, culminating in the availability of clean drinking water.
