The diagram shows the design and operation of a landfill site for domestic waste disposal. Overall, the process consists of three main stages – construction, usage and closure, incorporating both natural and synthetic materials.
During the construction phase, a large artificial pit is excavated, reaching natural rock formations. The base and walls of the hole are covered first in clay, followed by a synthetic material to prevent leaching into the surrounding ground. After the lining is complete, a drainage system, comprising multiple pipes and a tank, is installed at the bottom to manage liquid waste, finalizing the preparation process.
In the next phase, specialized trucks deposit household waste into the pit, with any liquid waste seeping downward through the drainage pipes into the collection tank. This continues until the landfill reaches its full capacity.
In the closure stage, the landfill is sealed with a thick clay layer to contain waste. A pipe is incorporated to allow gases to escape safely during decomposition.
