Summarise the information by selecting and reporting the main features, and make comparisions where relevant
The diagram shows how dirty water is changed into clean water using a simple system.
Overall, the process includes several steps, starting with pouring dirty water into a barrel and ending with clean water that can be used for drinking. The system uses two main containers and different materials to filter the water.
First, dirty water is poured into a plastic barrel, which has a plastic lid on top to cover it. Inside this barrel, there are three layers of materials: sand, charcoal, and gravel. The water goes through these layers one by one to remove dirt and impurities. The sand is at the top, followed by charcoal in the middle, and gravel at the bottom. Each layer helps to clean the water as it moves downward.
After passing through the layers, the filtered water flows into a storage drum through a pipe that connects the two containers. The storage drum is placed next to the plastic barrel. Finally, the clean water is taken out from the storage drum using a tap, and it is ready for drinking. This system is simple but effective for cleaning water.

The diagram illustrates the mechanism by which contaminated water is purified into potable water through a straightforward filtration system.
Overall, the process encompasses several sequential stages, utilizing a plastic barrel equipped with layered filtration materials and a storage drum, to effectively transform impure water into clean drinking water. The system relies on natural filtration to ensure the water is safe for consumption.
Initially, impure water is introduced into a plastic barrel, which is sealed with a plastic lid to prevent external contamination. Inside the barrel, the water passes through three distinct layers of filtration materials arranged in descending order: sand, charcoal, and gravel. The sand layer traps larger impurities, while the charcoal absorbs finer contaminants, such as chemicals and odors. The gravel, positioned at the bottom, further ensures the removal of any remaining particles, progressively purifying the water as it descends through the barrel.
Subsequently, the filtered water flows through a connecting pipe into an adjacent storage drum, which is designed to hold the purified water. From there, the clean water can be dispensed via a tap, ready for drinking purposes. This method provides an efficient and practical solution for water purification.
