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 diagram illustrates two types of filtration systems: cross-sectional filters and uncomplicated outdoor storage and refilling systems.
Overall, a cross-sectional filter contains three layers, while the uncomplicated outdoor storage and filling setup consists of four tanks that serve different functions. It’s worth noting that the first type of filter comprises multiple filter elements, whereas the second type contains only one.
The total capacity of a three-layer filter is 200 liters. The inlet forces untreated water into the first layer of the sand filter before passing through another layer of small stones and reaching the pipe with holes. Usable water then exits the system through an outlet pipe.
The second type of filter contains multiple units. Untreated water is stored in a separate tank. The water then goes to the next unit via a tap, and the filtered water flows into the storage unit, where it is stored until necessary. Individuals can utilize water from the tank by simply turning on the tap.
