The image depicts the process of producing drinking water; it starts with solar cells converting sunlight into electricity, powering a computer which controls an underground water pump; the pump draws underground water through a pipe to a water tank; within the tank, impurities are separated as the water is filtered through a mechanical water filter; clean water from the filter flows into a storage tank for household consumption; a direct line also connects the pump to this storage tank enabling direct consumption of drinkable water.
Given the complexity of the image, the above description may not be entirely accurate.

The graph shows how drinking water is produced by a solar-powered pump and water filter. As can be seen, there are 2 main stages in the process of producing drinking water, beginning with water in underground well and ending with water in moveable container.
At the first stage, solar panel under sunlight were connected with conventer and electricity, heading to a pump on underground well. Then, the water was pumped from solar-power pump into water tank with water filter inside it.
In the next stage, after drinking go through water tank, which is locating on a wooden flatform, it was filted by water filter. At last, drinking water was floated into removeable via a tap.
