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 image illustrates a cross-section of a sand filter, along with a water filtration and storage setup. Overall, it is evident that the sand filter consists of three distinct layers, while the outdoor filling and storage system consists of four tanks designed for filtering and storing water for household chores.
The total capacity of the three-layer sand filter is 200 liters, contained within a metal container. Initially, untreated water is introduced into the first layer of the sand filter. From there, it passes through a second layer of small stones before reaching a pipe that has holes. Usable water then exits the system through an outlet pipe.
The second type of filter contains multiple units. Untreated water is directed into these tanks sequentially. After that, the water flows to the next unit via a tap and then into the storage unit, where it is kept until needed. Each unit is easy to use; users simply need to turn on the tap to access the stored water.
