The diagram given illustrates the design of the construction of a contemporary landfill for household waste.
Overall, the diagram consists of 4 main steps, beginning with the preparation of the construction and ending with the use and closure of the landfill.
Initially, an artificial rectangular hole is dug down to the natural rock foundation beneath the surface. Then, a layer of clay and synthetic material are added to avoid the leak of dirty water. Multiple drainage pipes and a tank are placed at the bottom to collect waste and liquid.
In the next stage, household waste is put into the landfill. As the amount of waste increases, liquid flows into the tank through the pipes, ensuring the safety and the eco-friendliness of the system.
In the final stage, when the landfill is full, it is covered with a thick layer of clay. A pipe is placed, allowing the emission of gases. This helps the closed landfill safer and cleaner.
