With regard to the former subsection, a man-made rectangular-shaped hole is dug into a natural rock, bearing a minimal difference in its width and height. Once a ditch has been created, a wastewater holding tank is subsequently placed inside. After that, layers of clay and synthetic lining are put respectively on top of one another, before a row of drainage pipes must be installed on their surface.
As for the latter subsection, when in use, garbage is dumped into the previous hole by waste trucks until it is fully covered. Following this, a pipe is arranged with two ends, connecting the inner and external parts of the structure. In more detail, one designated end is connected to the drainage pipe system, whereas the other end is placed overground to allow gases to escape from the pit. Finally, the landfill is covered with clay material so as for not only preventing leakage but also undesired waste exposure to the surrounding environmen
