The diagram shows how to produce clean drinking water using a simple water filter system. This equipment has two storage drums used as filters and clean-water storage. Overall, this scheme consists of four main steps. Start with pouring dirty water, followed by filtering and keeping clean water, and finally by opening the tap to use the drinking water.
In the first stage, open the plastic lid then pour the unclean water into the elevated plastic barrel. In the second, water penetrates down through three filtering layers. The water goes into a sand filtration process to reduce sedimentary, the next filtration step involves charcoal and purification through the application of gravel. After this stage is complete, a pipe from the bottom of this drum then leads the purified water and flows into the second drum below.
In the final stages, the filtered water is saved in the lower drum with a closed lid. With a tap at the bottom of this drum, users allowed to drink this clean water.
