The diagram illustrates the layouts of a modern landfill for domestic waste disposal from construction to closure. Overall, the landfill is constructed with great concern for the environment by adopting latest technologies of contamination prevention.

The landfill is first created by digging a deep hole in the designated ground. It is protected by double liners made of plastic and clay so that pollutants cannot enter into the surrounding ground and the aquifer. Particularly, at the bottom of the landfill, there is a drainage system consisting of drainage pipes and a tank. When the landfill is in use, any liquid from the waste can be collected and treated through this system, thus diminishing its environmental impacts.

Once the landfill has been filled, it will be capped (covered) with layers of synthetic materials and clay to form a barrier between the waste and the surroundings. Its byproducts including the liquid and gases are transferred through separate pipes to a proper treatment facility. As a result, the closed landfill leaves almost no harmful effects and the site can later be reused for other purposes such as building a park.
