The image illustrates the stages of constructing, using, and closing a modern landfill for household waste. During construction, a man-made hole is created in the natural rock, lined with synthetic lining and drainage pipes leading to a drainage tank, with a clay base. In the use phase, household waste is dumped into the lined hole, with an outlet for waste liquid at the base. In the closure phase, the landfill is sealed with a clay cover and sand, and a pipe extends from the waste area for gas release.

The process describes how a modern landfill for household waste is manufactured.
Overall, it is clear that there are three main stages in this picture, beginning with the construction, and ending with the closure.
To begin with, the construction is separated into two stages. Firstly, a giant hole is dug from the natural rock. Subsequently, it is lined with a thick layer of clay, and followed by a synthetic lining layer. Then some drainage pipes and drainage tank are installed to remove the sewage.
The second stage is the usage, the household waste is put in that man-made hole, and the waste liquid is also removed by the drainage tank and drainage pipes. Finally, the giant hole is covered by clay, and because there is a lot of waste in it. Thus, the pipe is added to remove the toxic gasses.
