SANITARY LANDFILL || PLANNING AND DESIGNING || EnE 313 PIT

So what is a sanitary landfill? A sanitary landfill is a landfill that provides the least expensive and most commonly used waste disposal method. Solid wastes generated must be disposed properly to minimize their adverse effects in our environment, and sanitary landfill is a great choice, there are two options in creating a sanitary landfill namely wet landfill and a dry landfill, sounds great right? Wet landfills are landfills that increases the rate of stabilization of the solid waste in the landfill, with the use of leachate recirculation, studies show that it can speed up the rate of waste decomposition by up to 5 to 10 years. Dry landfills on the other side is designed to seal off the solid waste in hopes of reducing leachate production, therefore decreasing the possibility of leachate leakage outside of the landfill system, however studies show that solid waste stabilization is limited with the “dry” system. Lets proceed to how to plan a sanitary landfill, planning a sanitary landfill involves three steps namely feasibility investigation, operational data and site selection. The feasibility report contains the summary of the findings from an investigation of factors discussed herein, and should include advantages and costs of waste recycling, volume reduction, and waste minimization. The options for a new landfill must start with an investigation; these options include prolonging the life of an existing landfill, alternate disposal methods, and use of regional or private facilities. Operational data includes a detailed description of mechanical equipment that will be used for handling refuse and operating the landfill, and the methods of solid waste placement. It also includes data on the solid waste, for which disposal is required, including the types of waste, the amounts, and the variations in delivery rates. When possible, the information should be based on an analysis of solid waste from which the project will be located, or from a similar project. The site selection is considered as the most critical step in establishing a landfill disposal facility. Landfill siting must be balance between minimizing haul distances, which affects the economics of the landfill, and maximizing distances from housing areas, inhabited buildings and other undesirable locations. Lastly designing the sanitary landfill, sanitary landfill design is the process of developing a detailed description and plans that outline the steps to be taken to provide a safe, efficient disposal of the quantities and types of solid wastes that are expected to be received, it also involves outlines of volume requirements, site improvements (clearing of land, construction of roadways and buildings, fences, utilities), and all the equipment necessary for day-today operations of the specific landfilling method involved. The sanitary landfill designing also includes structures or equipment for controlling water pollution and the movement of decomposition gas, including the recommendation of a specific use of the site after landfilling be completed. Finally, determining capital costs and projected operating expenditures for the estimated life of the project. This includes parameters such as: Volume Requirements, Site Improvements, Control of Surface Water, Groundwater Protection, Gas Movement Control, Sanitary Landfilling Methods and lastly Summary of Design Considerations.
