Project Details

The Prairie View Landfill project with our client Waste Management saw Witech crews performing mass excavation services for this landfill in Wilmington, Illinois. Witech’s scope of work included new cell construction, placing and grading leachate aggregate, and capping a completed slope section.

One challenging aspect of this project was the wide range of soil conditions at the landfill, which made carefully coordinating our excavation plans critically important. These varying soil conditions made it so that not all material from the cut area was suitable for cell construction or capping, and some of the soil also wasn’t stable enough for heavy equipment. In addition, the project involved many long hauls from the cut to fill areas, with significant climbs up and down the landfill sections.

When we put the finishing touches on this project in September 2021, we will have performed 210,000 cubic yards of earthwork: 40,000 CY to the stockpile for future phases, 40,000 CY for daily and intermediate cover, 75,000 CY for the final cover and capping layer, 10,000 CY for the vegetative cover layer, 25,000 CY of compacted clay liner, and 10,000 CY of aggregate placed for the leachate drainage layer.

Our operations team did amazing work on the Prairie View Landfill project, adapting and modifying daily tasks to align with the various soil conditions we encountered.
