The diagram illustrates a simple method of purifying dirty water in order to make it suitable for consumption.
Overall, the system showcases how readily available natural materials and basic equipment can be utilized to produce drinkable water in just a few straightforward steps.
Firstly, a storage drum and a plastic barrel are positioned adjacent to each other, 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. Subsequently, a filter is constructed within the barrel by adding layers of sand, charcoal, and gravel. Lastly, a tap is installed at the bottom of the drum, and another one is placed at the top of the pipe.
The process commences by lifting the plastic lid of the barrel and pouring impure water into it. The water then passes through the filter and travels up the pipe into the drum, where it is stored. When the tap in the drum is opened, potable water is released for use.
