Band 9: The process of producing drinking water by solar power powdered pump and filter. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates the sequential stages involved in producing purified water through a solar-powered pumping and filtration system.

Overall, it is clear that the process is entirely self-sustaining, relying exclusively on renewable solar energy. The system consists of five main stages, beginning with the generation of electricity from sunlight and ending with the collection of clean water in a portable container, ready for use or distribution.

The process commences when a solar panel absorbs sunlight and converts it into electricity through a converter. This electricity powers a pump, which extracts underground water and channels it via a pipe into a storage tank.

In the next stage, the water is filtered to remove impurities. Following this, the purified water flows through a pipe equipped with a tap, which regulates the stream. Finally, the clean water is collected in a movable container placed beneath the system, enabling either immediate consumption or later distribution.
