ANSWER (8.0+):
The given diagrams illustrate how domestic waste is treated in a contemporary landfill. Overall, the process involves three main stages, namely construction, waste filling, and closure.
In the construction stage, a hole is dug in the ground, forming the shape of a horizontal rectangle. The bottom of the hole is positioned well over the natural rock layer. Once the hole is created, a drainage tank is placed at the bottom along one side of the hole. Next, a layer of clay and a synthetic liner are added to cover the surface of the storage area. Finally, a system of five drainage pipes is installed at the bottom of the area.
During the landfill’s operation and closure, trucks first transport domestic rubbish to the site and dump it into the storage space, where solid waste remains while liquid waste drains into the previously installed tank. Once the landfill reaches full capacity, another system of pipes is used to release gases from underneath the landfill, and clay is spread over the top to fully cover the area.
