The provided diagram describes how a simple water filter is assembled and produced clean drinking water.
Overall, the filter was constructed using plastic barrel as the main container, with layers of natural filter to purify the water before it flows to a drum to be stored as drinking water.
A glance at the image shows a simple water filter, along with the tools required to construct it. First, it requires a barrel made of plastic, where the filtration element placed inside the tank as water purification method. The materials need to be layered by order at the bottom of the barrel, starting from gravel, followed by charcoal, then sand. After the water poured in, the filtration tank should be closed with a plastic lid. Afterward, insert a pipe connecting the filtration tank to another drum, which will distribute the already purified water to the storage which equiped with faucet to tap the water that is ready to drink.
