The diagram illustrates the design of a modern household waste landfill.
Overall, there is a linear process with three main stages, beginning with construction and ending with waste management after a period of use, with several key components, including a pit, drainage pipes, and a tank.
In the initial construction stage, a large, deep rectangular pit is excavated in natural rock. This pit is first lined with a thick layer of clay, followed by a synthetic liner. At the bottom of the pit, a drainage tank is installed, while several drainage pipes are positioned on top of the liner.
Once the landfill is prepared, it is filled with household waste. As waste accumulates, excess liquid drains through the pipes into the tank at the base, preventing pollution of the surrounding soil. In the final stage, gas generated from the waste is collected via a gas vent, which is connected to the drainage pipes, while the landfill is sealed with another layer of clay.
