Landfill Notes
-1: On top of a landscape you can always see vegetation and, its prevents erosion of the underlying soils.
-2:Top Soil The top soil usually just maintains the moisture to maintain vegetation.
-3. PROTECTIVE COVER SOIL: It protects the landfill cap system which provides additional moisture to help the vegetation.
-4. Drainage layer: This is when a layer of sand or gravel is located the plastic mesh is called a geonet drain excess. This layer is for the stability of the landfill to prevent infiltration of water through the landfill cap system.
-5. Geomembrane: Thick plastic layer that forms a gap that prevents excess precipitation from entering the landfill and forming leachate. It also helps prevent the escape of landfill gas.
-6. Compacted Clay: It is placed over the waste to form a cap. This layer prevents excess precipitation, and help prevent from the escape of landfill gas.
-7.Daily Cover: At the end of every working period the waste is covered with up to twelve inches of soil. The soil keep it from releasing ordor.
-8. Waste: As waste gets thrown it is compacted into layers, it keep it from scattering.
-9.: Leachate Collection Layer: This is a layer of grave; that collects leachate and allows it to drain by gravity to a leachate collection pipe system.
-10. Filter Geotextile: It is located on top of the leachate pipe system to provide separation of solid particles from liquid.
-11. Leachate Collection Pipe System: surrounded by a bed of gravel, this section removes the leachate from the landfill and transport it to the leachate management facilities for treatment or another proper method of disposal.
12.-Geomembrane: This section is a thick layer that prevent leachate from leaving the landfill an entering the environment. This section is constructed with a thick plastic called HDPE.
-13. Compacted Clay: Located below the geomembrane and forms an additional barrier to prevent leachate from leaving the landfill.
-14. Prepared Subgrade: The native soil beneath the landfill are prepared as needed prior to beginning landfill construction.
