The image delineates the design of modern landfills for household waste in three stages: construction, use, and closure. In the construction stage, a man-made hole is dug into natural rock; the hole is then lined with synthetic material, drainage pipes, a drainage tank, and clay. In the use stage, household waste is deposited in the lined hole, with liquid waste directed by drainage pipes to the drainage tank. In the closure stage, the landfill is sealed with a layer of clay, and pipes are installed to manage gases generated from the household waste decomposition.
