The given diagram illustrated a blueprint of a modern landfill for household wastes
Overall, there are 3 main designs of a landfill: the construction, the working method, and the closure. It can be seen that a two-layer base in which household refuse is kept and toxic liquids are removed from the landfill by the use of a system of pipes.
So as for the construction of a landfill, commences with a giant man-made hole dug into ground above a bed of natural rock. Once the hole has been dug, it is then lined with a thick layer of clay, followed by a layer of synthetic material which helps to stop toxic waste substances from leaching into the surrounding earth. Drainage pipes and a drainage tank are also installed in order to remove the toxic waste liquids from the bottom of the landfill
Once the landfill has been built, it is ready to be filled with household waste. When used, the landfill is filled up with household waste, with the leachate being extracted and eventually flowing out of the site in liners. Finally comes to the steps in which once the rubbish has been converted into a mud-like compound, the landfill is sealed with clay, and gasses that are emitted as a result of the conversion is eventually pumped out of the hole
