High Density Polyethylene (HDPE) has exceptional resistance to all kinds of aggressive chemicals and corrosives, including soils. It is an ideal material for pipe used in the special soil environments of waste disposal areas. Today’s sanitary landfills require materials with proven long term performance including solid wall and perforated hdpe pipe.
To protect the enviroment, it is important to remove the water and keep the garbage dry. Leachate is water that gets badly contaminated by contacting wastes. It seeps to the bottom of a landfill and is collected by a system of pipes. The bottom of the landfill is sloped; pipes laid along the bottom capture contaminated water and other fluid (leachate) as they accumulate. The pumped leachate is treated at a wastewater treatment plant (and the solids removed from the leachate during this step are returned to the landfill, or are sent to some other landfill). If leachate collection pipes clog up and leachate remains in the landfill, fluids can build up in the bathtub. The resulting liquid pressure becomes the main force driving waste out the bottom of the landfill when the bottom liner fails.
Another major problem with landfills, is the production of methane gas. When your garbage is compressed there is very little room for any oxygen. When bacteria breakdowns your garbage, it creates a landfill gas, which contains mostly methane and carbon dioxide with small amounts of nitrogen and oxygen. To prevent the gas from exploding or bursting into flames, a system or series of plastic pipes are embedded within the landfill to extract the gas. In some cases, this gas is vented, burned off or the methane is extracted and used as usable energy source.
Pipefusion offers a wide range of products and services to assist in the collection and removal of leachate water and methane gas.
