The given diagram illustrates how a water filter is constructed and how it works to produce clean water.

Looking at the model, we can see the appearance of the water filter is a large tank with various materials inside. From the top, there is a large space for water, and under it are sand, charcoal, and gravel. All of these things are connected to a drinking water storage tank, by a hose or a pipe.

The process of making clean water is quite obvious. Firstly, impure water will be put inside the filter. Next, the water will go through various filter stages.After overcome the gravel stage, the pure water is then delivered to the drinking water storage tank, ready to be used.

Overall, the water filter is a complex design with a complex progress to make clean water. The design consists of three main layers-sand, charcoal, and gravel- allows water to flow through naturally by gravity, and it is clearly suitable for use in remote areas.
