The Winnebago Landfill is a modern Subtitle D landfill constructed with many safety features. The landfill has a composite liner system that consists of a base liner made of recomposed clay. On top of that a high-density polyethylene impermeable geomembrane is installed. A sand drainage layer on top of the liner system contains drainpipes to remove any liquids that collect on top of the liner. This eliminates the potential of
liquids being released from the landfill. The liquids that are collected from the drainage system are treated at the wastewater treatment facility in Rockford. Landfill gas, generated from the decomposition of the waste, is collected and used as a fuel source. A network of groundwater monitoring wells located throughout the facility is monitored regularly to ensure that the landfill is operating properly.

When waste comes into the landfill, it is spread in layers at the active fill area and compacted with special equipment. The waste in the active area is covered with dirt or other inert material at the end of each day. The landfill accepts municipal solid waste as allowed by law. The facility has a random inspection program in place to ensure that unacceptable material is not allowed into the landfill. We do not accept any items that have been banned from landfills by law. These include: yard waste, tires, white goods (refrigerators, washers, etc.), car batteries and hazardous waste.
