Band 8+ Sample Answer:
(Intro and Overview) The diagram illustrates how a modern landfill is built and used for collecting and treating domestic waste. There are three main stages, namely construction, use and closure, each of which consists of several small steps.
(Detail 1) Initially, an adequately large, rectangle hole is dug, and it is then lined with a layer of clay and then on top of that is a synthetic lining, most likely to prohibit leaking. The next step involves installing a series of drainage pipes at the floor of the landfill, which connect with a drainage tank which is located underneath.
(Detail 2) Once the landfill is ready for use domestic waste is emptied into it. Any liquid waste will be collected in the drainage pipes and stored in the drainage tank below. As soon as the landfill is full of rubbish, it is closed by covering the top with a layer of clay. Pipes connect the drainage tank to the top right hand-side of the landfill, therefore allowing liquid waste to be removed if necessary. Similarly there is a means for trapped gases to travel from the bottom of the landfill to a hole to the right of the clay roof. (193 words)
