The diagram shows an overview of a simple method to cleanse dirty water.
Overall, the process includes five stages, starting with pouring dirty water into the purification system and ending with the production of potable water.
Initially, dirty and unpurified water is delivered into the top of a plastic barrel. After that, filtration occurs as the dirty water seeps deeper through three layers of material, including sand, charcoal, and gravel, generating clean water.
In the third step, the filtered water is transported to a separate storage drum via a connecting pipe system. One end of the pipe is embedded in the gravel at the bottom of the barrel while the other end is connected to the storage drum. The cleansed water is contained inside the drum for a long period of time. As the drum is mostly enclosed, it is unlikely that the water will become contaminated. Finally, a tap is installed at the bottom of the drum, allowing safe drinking water to be dispensed into cups.
