The diagram illustrates how drinking water is obtained from an underground well using a solar-powered pumping system. Overall, the process is a continuous cycle with six main stages, beginning with the collection of sunlight and ending with water being dispensed into a portable container.
The process starts when sunlight strikes the solar panel, which is mounted on a pole above the ground. The panel absorbs this solar energy and transforms it into electricity. This electricity is then transmitted through a cable to a converter, a small box located at ground level, which adjusts the current so that it is suitable for powering the equipment.
Next, the converted electricity is sent underground through another cable to a pump, which is submerged at the bottom of the well. Once activated, the pump draws water upwards through a long vertical pipe. The water travels above the surface and is then directed into a large water tank, which is positioned on a wooden platform to keep it elevated.
In the final stage, the water stored in the tank flows out through a second pipe on the side of the tank. This pipe is fitted with a tap, which allows the water to be released in a controlled way. The drinking water is collected in a moveable container placed beneath the tap, and this can be carried away for household use.
In conclusion, the system relies entirely on renewable energy rather than fuel or mains electricity, making it an environmentally friendly and practical method of supplying clean water, particularly in remote areas.
