Environmental Containment Systems For Municipal Waste Landfills Are Comprised Of A Number Of Components

The soil barrier protective layer is 24 inches thick, and the six inches of cultivated topsoil that lies on top of it protects the underlying geomembrane while also promoting evapotranspiration & runoff of precipitation.

As a result of the use of a 60 mil (0.06 in) thick geomembrane (or a 40 mil (0.04 in) thick geomembrane, depending on what type of material used) and an underlying low permeability clay overlay, a composite barrier cover system is formed, that also prevents infiltrating rainwater from trying to reach the solid waste buried in the landfill as well as generating additional leachate.

The gas vent layer collects & regulates landfill gases produced by the decomposition of the waste material in the landfill. Read The Use of Computers in Entertainment

It is possible that the waste pile is more than one hundred & fifty feet thick.

When a main leachate collection & removal system is installed, it includes a series of drains & pipes buried under a layer of sand or gravel. These drains and pipes are meant to collect all the liquid leachate that has been released from the waste material. The leachate collecting system is supported by a geomembrane that is 60 mil thick. An incredibly low permeability clay layer and GCL (a thin produced layer of very durable textiles and very relatively impermeable clay) component is underlain by the 60 mm geomembrane at the bottom of the landfill, resulting in a composite liner. The leachate is collected being sent to a wwtp.

The secondary leachate collection & removal system at a landfill is a backup system of drains and pipes enclosed inside a layer of sand or gravel that is meant to collect any leachate that was not contained by the main leachate collection & removal system at the landfill. The secondary composite liners system is comprised of a 60 mil (0.06 in) thickness geomembrane undergirded by a 24 inch clay layer, which serves as a secondary containment system for leachate and works as a secondary containment system for leachate.

In order to safeguard the environment from toxins that may be contained in municipal solid waste, this design has been implemented. In addition to the landfill siting plan, that either prohibits the construction of landfills in ecologically sensitive areas, on-site environmental monitoring equipment, that also monitor for any signs of groundwater contamination as well as landfill gas, provide greater protection against landfill contamination and gas emissions.
