Municipal solid waste landfill failure case study

In recent years, with the advancement and development of cities, waste disposal has become one of the basic needs of humans, and this is only possible through the design of a Engineering Municipal waste landfills. The importance of designing and planing the proper disposal of municipal waste is due to the fact that Landfills retain a large amount of urban waste accumulated over many years, and in the event of their destruction, a massive amount of waste creates. As a result of this, other than economic costs it can cause many environmental problems, as well as many human mortalities. For this reason, the study of the causes of the failure of the Landfills, which occurred in the past, can help in preventing the same occurence in the future. In this study, the defects of three landfills of Payatas, Donna Jona and Kettleman Hills are discussed. In each case, the failure mechanism is first examined, and then the conditions that caused the failure are discussed. In general, in order to prevent a defect ,in addition to proper design, it is necessary to maintain special controls and observations during the operation and after the end of the utilization period.
