The diagram depicts a simple construction of a water purifier and how it is used to assemble potable water. Overall, it can be clearly seen that there are four stages to produce drinkable water, it starts with pouring the unclean water into a container that contains many particles needed, and ends with the release of clean water from the tap.
There are two drums with a plastic lid that should be prepared to start the operation of purified water. The first drum is filled with grave as the base layer, then charcoal, and sand as the top. In addition, other tools are provided: pipes to connect with the second drum and taps to drain pure water out.
The H2O filter process begins when the contaminated water is poured into a plastic barrel, and absorbed through three different layers of material. After that, it is transferred to another drum through the tube. The last stage is when the drinking water is produced and ready to be consumed.
