The given picture illustrates a rudimentary system that transforms contaminated water into potable water.
Overall, it is clear that the water filtration system is showcased how to utilize natural materials and basic equipment to produce drinkable water , which primarily comprise two components: a filter assembly and a storing drum, involving some example steps.
In terms of the filter assembly, which is essentially a cylindrical container with a plastic lid and a series of layers, consisting of sand, charcoal and gravel respectively. Firstly, water is poured into the filter assembly that continues to go via three mentioned layers of the system to remove purities.
After that, the filtered water then flows into the storage drum through a plastic barrel, which is positioned adjacent to the drum with the top of the latter higher than the former. These two components are connected by a pipe running from the bottom of the barrel into the side of the drum. The process commences by traveling up the water through the pipe into the drum, where it is stored. When the tap in the drum is opened, potable water is released for use.
