The picture illustrates how a current landfill is constructed for the disposal of domestic waster.
From an overall perspective, this artificial process involves a number of distinct stages, beginning from excavation a large hole, following by further constructed and installed drainage system, then it come to using stage and ending with the formation gas come out from the decomposing process for family to use.
As can be seen from the initial stage of the process, a large site is dug to make a man-made pit, after which this hole is set with a drainage system includes drainage pupes and a thin, small space for tank, while beneath it is two layers of clay and synthetic substance.
The process continues with the household garbage is gathered and deposited dumped into the hole while the liquid waste is flow into the small tank space for the continues processes. Following that the closure step, another layer of clay will be sealed the pit surface to start the decomposing process, then the gas product is channeled out of the hole by drainage pipes.
