The image depicts a diagram titled "A simple outdoor filling and storage system," illustrating a water filtration and storage setup. The system includes a cross-section filter at the top comprising a sand filter, tiny stones, and pipe holes, connected to a 200L metal container labeled inlet. The filtered water flows from the outlet into a storage system for untreated water, featuring a tap for dispensing. The diagram presents the flow of water from collection through filtration to storage, eventually designated for household use, demonstrating a basic infrastructure for managing and utilizing water supplies in a simplified schematic form. No numerical data points or percentages other than the 200L capacity of the metal container are provided in the image.

The flow chart presents two different processes for making water safe for domestic use.
Overall, the first process, known as the Cross-section filter, consists of three filtration stages. In contrast, the second process is simpler, involving just two steps, and is typically used in outdoor settings.
Looking in more detail at the Cross-section filter, untreated water first enters a 200-liter steel filtration system. This system contains three sequential filters: the first filled with sand, the second with small stones, and the third featuring numerous tiny holes in pipes. Each stage plays a role in effectively removing various impurities as the water flows through.
In the second process, untreated water is first gathered in a container. The water then passes through a sand filter, with the flow controlled by a tap. After filtration, the clean water is pumped to a storage unit where it is kept until needed for household purposes.
