The illustration shows the steps of turning impure water into pure water.
Overall, the system consists of four steps: pouring, filtration, collection, and dispensing.
Firstly, the polluted water is poured into a plastic barrel that is covered with a plastic lid. The water in the barrel is then passed into three different materials: sand, charcoal, and gravel filters to refine the dirty water.
For the next step, the water is put into the storage drum to collect all the pure water. Finally, the pure and unpolluted water is ready to drink with no hesitation, and it is healthy to consume.
