Approximately 115,000 cubic yards of soil was excavated to create the new module. 80,000 square feet of excavated slopes were surface with a shotcrete slope veneer. Low-permeability clay was imported and placed over the 3-acre floor of the module prior to deployment of geosynthetic clay liner, HDPE geomembrane, and leak detection geocomposite.

Approximately 1,200 lineal feet of 6" perforated HDPE leachate collection pipe was installed to drain to a sump and leachate pump system. A 12" thick layer of gravel drainage layer was imported and placed over the geosynthetic liner utilizing low ground pressure equipment. Geotextile fabric was installed over the gravel.

Finally, 15,000 cubic yards of soil operations layer was processed and placed over the geotextile to allow placement of refuse.
