The picture illustrates how clean water is filtered. Overall, there are two main stages in the process: filtration above a storage tank and storage and consumption from a lower tank.
Regarding equipment, a sizable storage drum has a plastic lid to avoid exposing the water to environmental factors. The plastic barrel is made up of three layers: sand, charcoal, and gravel. This filtration barrel is connected to a storage tank by a curved pipe.
At the beginning of the process, impure water is poured into a container, where the filtering process takes place. The water passes through the layers of sand, charcoal, and gravel to eliminate impurities. After successfully filtering, the water flows through a special pipe into the storage tank, where it is ready for consumption by pressing the tap open.
